First Impressions - 2013 BMW M5



The following article is an earlier post done for another website that is no longer in business. I've moved it here in an effort to consolidate all of my posts. Consider it ride back in to time. Enjoy!




2013 BMW M5


It's been 40 years since BMW's secret skunkworks M Division has been pumping out uber powerful, yet subtly styled cars for the discerning executive driver. The kind of driver that wants super car performance without drawing attention to himself. Since it debuted, the M5 has been the de-facto bogey by which all other pretenders to the crown of super sports sedans are judged. Through each generation, the M5 offered opulent levels of luxury with seating for five, while packing enough horsepower and handling to make even the stalwart Ferrari jock think twice before a challenge.The last generation E60 M5 packed a Formula One inspired, high revving 5.0 liter V10 which powered the rear wheels with 507hp at a screaming 8200 rpm redline. Naturally aspirated, high revving engines have been a BMW M hallmark ever since the outfit's inception. Equipped with a fast shifting 7 speed sequential gearbox, the E60 could sprint from 0-60 in 4.5 seconds while belting out the closest thing to Formula One race car's engine wail. Despite this performance, the E60 was often derided as being too raw (one of my personal favorite qualities), too complicated (3 settings for the engine, 11 settings for the transmission plus countless others for varying systems) and the dimwittedness of the transmission when not going balls out. Basically, the M5 worked extremely well on the track but felt misplaced at saner speeds and calmer settings.


2005-2010 E60 M5


Enter the new F10 model, which BMW probably wouldn't admit as much, but addresses most of the E60's minor (okay, major) shortcomings. Gone is the high revving-but-quite-thirsty V10 and herky-jerky SMG single clutch transmission, replaced by a new "M TwinPower Turbo" twin turbocharged, directed-injected, 4.4 liter V8 engine and an equally new seven speed dual clutch transmission to dole out the twin-turbocharged engine's impressive 560hp and 500 lb-ft of torque (more on this impressive yet major departure of an engine later). The basic 5 Series chassis has been substantially revised with an aluminum-intensive suspension (the rear components mounted in a rigid cradle to alleviate the flex of rubber bushings), an electronic version of the M differential which can split torque between the rear wheels for maximum grip, a tuned hydraulic steering rack (because the standard electronic unit lacked feel) and six piston brake calipers per wheel.

One of the more peculiar traits of the new F10 M5 is the engine's lack of aural character, at least compared with its raucous predecessor. The E60's V10 had such character that it made the hair on your skin stand up every time the driver touched the gas pedal. The new forced induction V8 on the other has hand is almost too refined. M engineers allegedly tried everything to alleviate this muffling effect of turbocharging (and the isolating effect of the 5's platform) by employing a number of options such as routing the intake housings closer to the firewall and cabin, installing microphones next to the intake and piping the sound directly into the cabin, none of which worked to their favor. They finally decided to use recorded sounds of the engine revving through its range and playing the sound back through the sound system in tune with the driver's placement of the throttle. Artificial yes, but it could be worse.

One thing this new M5 improves on is in the electronics area. The E60 driver was simply overwhelmed with settings for everything controlling the car and no simple way to access or change them. This was the effect of the oft-derided iDrive system. The new F10 seeks to change this with simpler settings and easier access to them with either buttons or a simplified version of iDrive. Where the previous SMG transmission had ELEVEN (how quickly would you like your head snapped off?) settings, the V10 having THREE (how much power do you want?) settings along with a myriad others (some as trivial as allowing timer settings for the interior/exterior lights...really?), the F10 pares all of this customization down to the driving details in four simple modes: Economy, Comfort, Sport and Sport+. In Economy and Comfort mode, the transmission and suspension are tuned to make the M5 as docile as a regular 528i, the transmission slurring between gears (shooting for the highest in Economy) and the suspension absorbing bumps and giving a very compliant ride. Switch to Sport and the engine note becomes noticeably angrier, the transmission swaps gears more aggressively, steering gains more load and the suspension firms up. Sport+ stiffens up the springs even more, adds even more heft to the steering and turns the M5 into an apex eating, turn gobbling, straights chomping monster. These settings are programmable through two M buttons on the steering wheel, allowing the driver to customize and store preferences (easier done here than in the E60). North America can take comfort in the fact that unlike the previous M5 which offered a manual transmission late in its life cycle, one will be offered in the new F10 from the start (without the penalty of not being able to switch off traction and stability control completely...and the heavens rejoiced!)


2013 BMW M5



Now, about that engine. Why turbos? Why forced induction? Why abandon a central theme important to M heritage by throwing away natural aspiration in favor of turbocharging? If you're an M enthusiast you can recall some time in BMW's history when uttering the term "forced induction" in a BMW building was akin to showing the Nazi sign. At Buckingham Palace. While dining with the Queen. It was unthinkable. Well, you'll have to get over it and cut BMW some slack. We now live in an era where fuel isn't as cheap as it once was and the reduction of vehicle emissions is now a central part of every automaker's R&D. The Germans are not immune to this and in order to comply with ever tightening emissions regulations, BMW has had to forego this central tradition (if you need any more proof, the next M3 will also use some form of turbocharging while downsizing from its current V8 back to a six cylinder). However, it's not all gloom and doom. With the new turbo V8 comes a new emphasis on economy. The S63B44Tu is an evolution of the S63 engine (itself a M-ified version of the regular N63 4.4 liter in 550i/750i sedans) used in the X5 M/X6 M high performance SUVs. As such, it boasts 30% better fuel economy ratings than the old 5.0 liter V10 of the E60. Sure the engine redlines at a tamer 7200 rpm, but for that you get 53 more horse over the old V10. Much more impressive is the jump in torque from 383lb-ft to an even 500lb-ft at a more accessible 1500rpm and the torque curve is as flat as the Great Plains. Drivers of the old M5 take notice: revving is not required but if you do, hang on.

Despite the F10 M5's gain in weight (thanks to the 5 Series architecture being based on the larger 7 Series) BMW has worked hard to minimize this penalty by using as much lightweight materials as possible throughout the car. Aluminum comprises the hood, fenders and doors as well as ultra high-strength steel through much of the chassis. Still the M5 comes it at a porky 4250lbs, some 200lbs heavier than the outgoing E60. Continuing the M tradition for Q ship styling, the M5 sports subtle exterior tweaks over the regular 5 Series that only the M faithful will identify at a distance. Larger air intakes at the front, larger fender flares framing 19 (or optional 20) inch wheels, a lowered suspension, the signature quad pipe exhaust and a subtle trunklid spoiler along with a sprinkling of M badges are among the calling cards for this cruise missile on wheels. Compared to the Bangle-esque styling of the E60 with its dramatic, flame surfaced exterior, the F10 model is quietly exotic. In many ways, it recalls the executive yet wolf-in-sheep's-clothes styling of the cult-status E39 model.




The 2013 BMW M5 should be on sale as of this writing at an MSRP of $90,795 (including $895 destination/handling). Go crazy with options like the Driver's Assistance package which includes systems such as blind spot warning, lane departure warning, side and top view cameras; the Executive package which further enhances luxury with heated rear seats and steering wheels, power trunklid, soft close doors plus a DVD entertainment system with screens in the front headrests (in case the kids get bored with your track driving)  and you're looking at a price tag of well over $110,000. Eye watering for sure but look on the bright side, that Porsche driver in the next lane will never know what hit him.

First Impressions - 2014 BMW M4




It's a bittersweet day M fans.

Rejoice for with the new F30 BMW 3 Series comes the promise of a M-ified version, only this time around (and for the rest of eternity) the vaunted M3 badge will only apply to the 4 door car. That's right. The arrival of the BMW 4 Series (no longer the 3 Series coupe) also means that the badge 'M4' will be affixed to the super coupe from BMW's M division.

Say what?

Let me explain. Exhibit A: Audi. Rather than make an A4 2 door (like they did with the A4 convertible...sorta), they branched off the 2 door version into the A5 (and with it, the S5 and hyper RS5) even though both cars share the same chassis. This has worked wonders for Audi and BMW is keen to follow suit. But is that such a bad thing though? The 3 Series Coupe has always been the stylish brother of the 3 Series lineup (which included 4 door and 5 door wagon variants) so in BMW's think tank, it made sense to branch off the 2 door into it's own line, sort of like the 6 Series is essentially a more stylish 2 door version of the 5 Series. Besides, with the arrival of new 3 Series variants like the Gran Turismo (see 5 Series GT for ugly reference) it was probably for the best.


So now, on to what makes this M4 so special (sounds weird saying M4 doesn't it?). Unlike the E90 M3, which sported a high revving 4.0L, 414hp V8, the new M4 will jump on the downsizing trend that has gripped the automotive world in the name of greater efficiency and, in a positive way, back to BMW's bread and butter engine configuration. In the V8's place will be a highly tuned version of BMW's legendary straight six coupled with two turbochargers and not related to the 335i/435i's N55 single turbo 3.0 liter (the M5's twin turbo 4.4 liter V8 is closely related to the same unit used in the 550i) or the earlier N54 powerplant. Displacing slightly more than 3.0 liters, power is rumored to be in the neighborhood of 420 to 450 horsepower with torque trouncing the paltry 295lb-ft of the naturally aspirated V8 by a significant margin. Figure closer to 400 lb-ft. The high-revving nature of the previous M3 will be retained, despite the forced induction employed by the new engine so look for a redline of around 7000-8000 rpm. BMW's 7-speed DCT dual-clutch transmission will send torque to the rear wheels (though a manual transmission is very likely) but don't expect BMW to follow Mercedes AMG on the AWD train. M engineers specify weight and balance as the primary reasons for turning their noses up at sending power to all four wheels, though the electronic M differential will have the ability for torque vectoring between the driven wheels. To keep the M4 light on its feet, BMW has employed more than a sprinkling or carbon fiber composites, particularly in the roof, trunk and hood with the emphasis on keeping the weight low and centralized. Bucking the bigger-is-porkier trend, the M4 will actually weigh less than it's predecessor by a good margin.


A look at the images reveals nothing less than something that came out of the M factory (toxic waste green hue aside). Signature cues include the large vents below the front bumper that provide cooling to the large carbon ceramic brakes as well as a carbon fiber front splitter for increased downforce. Unlike the bigger M5, these vents are more aggressive in design and feature multiple aerodynamic enhancements. The twin-kidney grille features unique inset slats and the traditional power dome in the hood. Just behind the front wheel wells, BMW has created functional fender vents it calls 'Air Breathers', beginning a character line that flows down the sides up to the widened rear hips. Large 20" wheels in typical M design are stuffed inside the wheel wells that, in tune with the widened hips, serve to enahnce the wider track of the rear end. The stylish character line ends in a rear unique to the M4, featuring a fully integrated tail spoiler and lower diffuser housing M's signature quad tailpipes finished in carbon fiber. Perhaps the coolest feature on the M4 concept is the roof which, also finished in carbon fiber, sports the just-visible M colors of blue, purple and red in stripes. The suspension has seen a thorough going over with wider tracks front and rear and a fully reworked rear suspension that features lightweight aluminum in the majority of its construction. Alas, the M4 will swap hydraulic steering for an electric unit, but before you take up flaming torches and pitchforks, the M engineers sweated the details to ensure that steering feel was not lost in the transition. The E92 M3's steering was a benchmark for feel and effort so look forward to the M4 to preserve that special touch in your hands.



Expect the production M4 and its four door companion to be unveiled in early 2014 with sales a few months after at a price starting in the $60k range. Like previous models, a convertible variant will follow (and here's hoping North America gets a wagon). With Audi RS and Mercedes AMG cranking out ever higher performance vehicles, the pressure is on BMW to deliver a car that will meet the Germans head on (and head off the new kid Cadillac ATS-V) keep the M badge as the standard bearer of the segment. Though calling the new car the M4 will take some getting used to, the performance being previewed should encourage M enthusiasts to accept the new car. And if the the new name still bothers you, there will always be an M3 available on the next stand. If you're willing to accept two more doors that is.

Quick Spin - 2012 BMW 328i

2012 BMW 328i Modern Line




The King of compact sports sedans is back.

The BMW 3 Series, arguably the most sporting of luxury sedans, has carried the torch as "The Ultimate Driving Machine" for the company since the 2002 model of the 1970s. Known for its compact size, yet playful nature, this model evolved into what we now call the 3 Series. With each generation, the 3 has gotten bigger, more powerful and more technologically complex. As we know the car today, it has been an all six cylinder lineup. The turbine smoothness and sonorous snarl of the inline six cylinder has been a BMW calling card for the 3 Series, from base model all the way up the last generation of the fire-breathing M3. Today however, the economic and environmental climate has changed and so too have automakers' take on efficiency. In response to this new challenge for environmental awareness and increased efficiency, BMW has chucked the naturally aspirated 3.0 inline six from the base model of its new F30 3 Series and introduced a new turbocharged 2.0 four cylinder. Outgunning the old six in terms of power and efficiency, the new four chucks out 240hp and 260lb-ft of torque, improvements of 10hp and an astounding 35lb-ft of torque. As part of BMW's 'Efficient Dynamics' program, the 328i is equipped with a host of technologies to deliver not only outstanding performance, but outstanding fuel economy as well. Available transmissions include a 6 speed manual transmission and a new 8 speed automatic. Of course if you need your inline six fix, the up-level 335i aims to please. Equipped with the 300hp/300lb-ft of torque N55 turbocharged 3.0 inline six, that flows its power through either the 6 speed manual or a 6 speed automatic, you won't have a want for more speed and power (and for the crazies, the 414hp V8 M3 is always there though based on the now obsolete E90 chassis).



2012 BMW 328i Interior



In remaking its most important model, BMW decided against a drastic restyle (remember the Bangle era?) and instead focused on a subtle yet noticeable surfacing of the exterior. The old E90 model was a handsome car that has aged well but in order to be more distinctive, BMW applied a slightly bolder approach. The signature twin kidney grill is more pronounced and the headlights now flow into it, the other signature BMW look - the "angel eye" driving lights - have a squatter appearance with the headlight fixtures flowing further back into the fenders. The lower intake is now a full length piece that also incorporates the fog lights. The new 3, always panned for cramped rear accommodations, features a longer wheelbase and slightly wider tracks front and rear. This translates into better interior room for four with more legroom for rear seat occupants (3 rear passengers is still a squeeze but at least they won't riot as before). German cars have always been known for stark, cold interiors and BMW is probably the best known (or most infamous) for this. My tester was a Modern Line 328i decked out in sumptuous leather called "Dakota Oyster" with a nice "Fineline Pure" wood trim (seriously, who comes up with these names?). The seats felt good and offered great support and finding a good driving position was made easy by the full powered 8 way adjustable seat and tilt/telescoping (unpowered) leather steering wheel. The interior felt rich and nicely complimented the Mineral Grey Metallic paint of the exterior. The iDrive system (ridiculed for years by the journalist community for its too-complex operation) has been further revised and is now simpler to operate. Climate controls are now separate items and no longer do you need to dive into menus just to tune the radio or adjust the volume settings. It must be noted here that the old ordering system is no more. BMW now offers the new 3 Series in four distinct "lines": Base, Modern, Luxury and Sport. Base models allow for a bit more personalization of equipment and features, Modern comes with more features standard while Luxury comes with yet more features as well as exterior revisions (chromed kidney grill and lower fascia, different wheels) to distinguish them from lesser models. Sport Line models feature large 19" wheels with summer tires and altered suspension settings as well as a blacked out grill and fascia.














 On start up, one expects to hear the whine and steady, smooth idle of an inline six under the long aluminum hood. Surprising then that, even with the knowledge of an inline four present, that the idle would shock me as it did. The turbocharged 2.0 four comes with direct injection and its clatter, although quiet was almost diesel-like, the *tick-tick* of the direct fuel injectors working away at the cylinders.  The 328i always starts up in Economy mode along with Auto Start/Stop engaged. This system is controlled by the 328i's electronic brain and, after learning the driver's habits, shuts down the engine to conserve fuel at appropriate times when the car comes to a complete stop. Once the brake pedal is released, the engine fires back up allowing the driver to continue on his way. The 8 speed auto also receives a remap of its shift points and, once underway, will quickly shoot for top gear. In order to encourage efficient driving, a display in the instrument panel tracks in real time how economical your driving is and will actively coach you, even by applying opposite pressure on the gas pedal to ensure smooth slow take offs from a stop. The start/stop feature was unnerving at first and was hardly subtle in its operation but one gets used to the sensation of the engine firing up and shutting off after a while. The computer is smart enough to know when the car is in heavy traffic and will not shut off the engine unless the car is stopped for periods longer than 5-10 seconds. Or you can completely shut the feature off by pressing a button if it annoys you. I certainly did. Fuel economy ratings for the 328i are 24 city/32 highway (revised by the EPA from previous numbers of 24 city/36 highway).


2012 BMW 328i Modern Line's 8" Central Screen



Driving through the Coral Springs area, the car rode comfortably and absorbed bumps that would have otherwise been felt in the old car. BMW has pretty much perfected the ride/handling balance of its cars but tribute should also be given to the new electronic dampers fitted to 328i. In Comfort mode, the ride was almost limo smooth but not floaty, the new electric power steering was quick but almost devoid of feel and communication, quite unlike the last car's hydraulic steering which was chatty by comparison. The 8 speed slurred through its ratios but was still quick to downshift a few gears when prodded. The turbo four is tuned for almost zero lag and delivers its torque across a broad RPM range and as such, passing maneuvers were effortless. At a traffic light, I switched to Sport mode and the change in the 328i's character was, in a word, noticeable. I could feel the electronically adjustable dampers stiffen, the engine's note change to a more aggressive idle while the computer remapped the transmission's shift points. The change was also noted on the 328i's 8 inch central screen by showing the damper setting and tune of the engine. It was as if the whole car went into attack mode, ready to pounce on the Audi A4 driver that was in front. The light went green and a stab of the throttle was met by instant thrust. Where the old car necessitated revving the engine to get power (a joy in itself), the new turbo four doesn't require it, exhibiting right-this-second torque delivery. Through a turn, the 328i exhibited almost no roll and remained flat as I negotiated a series of quick left to right lane changes to get around slower traffic. This car is remarkably quick off the line and the A4 that was in front a few seconds ago? A red blip in my rear view mirror. Sensing the aggressive driving (don't try this at home kids!) the 8 speed learned my style and properly held gears all the way to redline. Manual shifting produced quick enough shifts but leave the transmission in auto and it's intelligent enough to know which gears are sufficient for the task at hand.  A race track or autocross would've been the proper place to wring out the 328i but even here on public roads, it's good to know that despite the car's nod to comfort, BMW hasn't neutered its playfulness. Lightweight materials in its construction play a role here and is yet another effort to increase the car's efficiency. Fitted as it was with the equipment onboard, the 328i weighs barely more than its predecessor. An aluminum hood and trunk lid, aluminum intensive suspension components and ultra high strength steel construction all contribute to the 328i's minimal weight gain. The engine itself, which is some 50lbs lighter than the heavier inline six it replaces, also serves to lighten the weight over the front wheels, increasing the car's quick turn-in behavior.


328i Modern Line's 18" wheels




Throughout the drive I faced a bit of a conundrum: I was actually having more fun here than I anticipated. Not once did I yearn for the excessive power of the 335i's 300hp/300lb-ft of torque, turbocharged 3.0 inline six. Having driven the old 328i, the old naturally aspirated inline six sounded sweet throughout the RPM range (in fact, it relishes revving right up to the fuel cutoff point), but I always felt that it needed more power. With the new model, you lose the turbine-like quality of the six but gain such an impressive amount of torque with almost no lag that the tradeoff is very reasonable. Besides, unlike the old six that made power right up to redline, the four is pretty much out of breath by 6000 RPM, though it does emit a pleasant bark from its twin tailpipes, not the sound one expects from a BMW but sporting and aggressive all the same. In fact, I would imagine that the heavier engined 335i's transient responses might be slowed somewhat by the increase in weight over its front wheels. So good is the 328i's power and torque delivery that, equipped with the requisite M Sport package (larger wheels, stiffer suspension), this might be a better sports sedan than the more powerful 335i. Put both on a racetrack and, while the 335i will hold the straight line acceleration advantage, the 328i driver will always catch up in the turns. I'm even starting to suspect BMW has underrated the 328i's power rating.


With each generation of new car getting larger and more complex, it's good to see BMW holding the line with its new 3 Series. Yes the new 328i may be a bit larger than the car it replaces, but BMW has worked hard to preserve the spirit and playful nature that makes the 3 Series such an exciting car to drive. Sure the naturally aspirated inline six is gone from the lineup in a nod to increased fuel efficiency, but the smaller, more powerful turbocharged four more than makes up for that.

Now price isn't the only reason to go for the base model and you won't be disappointed.

First Impressions - 2013 Cadillac ATS

2013 Cadillac ATS

In the world of compact luxury sedans, the BMW 3 Series has reigned supreme for a number of years. It has successfully fended off competitors like the Infiniti G sedan and Lexus IS that repeatedly attempted to knock the 3 off its pedestal. The trouble with being King of the segment is that you're effectively a bulls-eye for would-be rivals. Nothing has come close to the Bavarian's apparently perfect mix of ride and handling (even though said competitors would have you think otherwise). Some rivals have tried to meet the 3 Series head on like the Lexus IS, even spawning the IS-F to take on the M3. Others, like Infiniti and Cadillac have gone the "tweener" route: cars that are larger than the 3 but smaller than the next level, the mid-size segment. Cadillac tried this option with its original CTS and met with success but over the years, even it realized that a more targeted response to the 3 Series was needed.

Meet the 2013 Cadillac ATS

Designed from the ground up to be a direct competitor to the Bavarian, the ATS is built on an all new RWD platform codenamed Alpha, that is said to be both lighter and stronger than the 3 Series, yet offer the same subtle ride/handling balance that has come to characterize BMW. The exterior styling, like other Cadillacs, can not be mistaken for anything else, except a slightly smaller CTS. Employing the brand's "Art & Science" theme of its big brother, the ATS rounds off some of the sharper edges, giving the sedan a slightly curvier look than the razor-edged CTS. The overall look is elegant, yet engaging and sporty.

However, one of Cadillac's main design briefs with the ATS was its performance; more to the point, that it be equal or better than the competition and the ATS more of less achieves this goal on paper. Spending considerable development time on Germany's Nurburgring race track, Cadillac engineers honed the ATS' platform and engines to better that of BMW's offerings (using the previous E46 version as inspiration). Equipped with GM's Magnetic Ride Control (dampers filled with magnetorheological fluid that change in viscosity when passed through a magnetic field) and 50/50 weight distribution, Cadillac promises the ATS will be light, nimble and seriously fun to drive.

2013 Cadillac ATS

The 2013 Cadillac ATS will be equipped with three different engines at launch. The base ATS will have a 2.5 liter, naturally aspirated inline 4 cylinder good for 200hp and 188lb-ft of torque and 30mpg on the highway. The serious enthusiast though will look to the upper level engines for serious fun. Slotted above the 2.5 liter is a 2.0 liter turbocharged and direct injected 4 cylinder putting out 270hp and 260lb-ft of torque, an effective challenge for the new BMW 328i's turbocharged, 2.0 liter 4 cylinder. Topping off the range (at least until the inevitable monster ATS-V) is the ubiquitous 3.6 liter direct injected 318hp V6. Cadillac has recently announced a diesel engine for the ATS at some point in its first life cycle, although it isn't confirmed if it will be offered for the American market. Transmissions will be a choice of either 6 speed manual or automatics.

On paper, the ATS looks to be a credible competitor in the compact luxury sedan segment. With claims of lightness, sportiness and efficiency, Cadillac's newest offering has the potential to accomplish what the tweener CTS hasn't quite been able to do.
Can't wait to see what the ATS-V will be packing. Stay tuned for a first drive!

Check out Cadillac's Super Bowl ad for the new ATS here.

[UPDATE] Cadillac has launched a new configurator for the ATS that allows you to mix and match options, just in case you were wondering about that manual transmission options availability on the 3.6 V6 (it's not...sorry). Pricing hasn't been included (coming later).
