SMG skeptics, protest no more. The future of transmission technology is here and the path is utterly clear. The future begins with the third-generation SMG transmission in the E60 M5, a seven-speed close-ratio unit designed from the start to be an SMG-only transmission. Why do I start a first look of such a remarkable new car by ranting and raving about its transmission, you ask? Because it is, without a doubt, the heart and soul that characterizes the new M5-and it is flawless. Without it, this new M5 would be yet another overpowered trophy car for yuppies to do burnouts and flaunt their wealth in.
I assume that as you are reading this, you already memorized all the specifications of this M5, much like that first dream bicycle that you ached for. I won't bore you with that. For the engineer in you, details can be found online at www.europeancarweb.com.
M GmbH's tradition of creating an independent car based on an existing BMW chassis is blatantly evident in this M5, which far exceeds any differentiation on previous M cars. Again, the reason behind the alter ego is the application-specific SMG coupled with the high-revving V10 and active vehicle handling aids. This is no longer just a punched-out 5 Series with better suspension.
The new package creates an entirely different car. Not once did I even think of the existing 5 Series while behind the wheel of the new M5. Even with all the hype and anticipation, this M5 will totally blow you away every time you get behind the wheel. The only clue to the M5's origins is in its appearance. Changes include sporty but discreet front and rear bumpers, aero mirrors, a functional M fender grille, side sills, bulging fenders, and some serious exhaust piping.
In my option it's still not a far enough departure from the base-model E60. Luckily, you can't see the car once you're behind the wheel, where you should be spending most of your time. Once inside, the active side-bolster seat supports, Alcantara roof lining, M steering wheel and heads-up display all hint at the driving experience to come. There isn't even a sunroof to creak as the chassis flexes under hard load. I can't recall the last time I've sat in a BMW without a sunroof.
To compensate for nearly every control being integrated into BMW's notorious iDrive, the M5 features extra buttons that can provide hours of additional entertainment. There are four essential buttons next to the shifter to note: Power, DSC, EDC and SMG shift-level-which allows you to chose from 11 programs available in automatic and sequential modes, combined.
The Power button switches the engine management between 400 and 500 horsepower modes because there really are times when there is too much power.
The new Dynamic Stability Control (DSC) for the M5 can be switched off for spirited driving, but there really isn't a need to with this car. DSC can be enabled in two modes: One very much like that found on non-M BMWs and a second one that is tied into the Mdrive configuration, allowing for power oversteer and wheel-spin launches. Te Mdrive DSC is adequate for the most aggressive and seasoned drivers on any road condition.
Electronic Dampener Control (EDC) is yet another aid that actively varies suspension dampening for three different configurations and achieves a controlled yet firm ride on the 19-in. M-style wheels. EDC also stipulates which of the two steering ratios the Servotronic system uses. Gone is BMW's active steering mechanism, which continually varies the ratio and takes away from the race-car predictability inherent in all M cars. In addition, the buttons give passengers plenty to play with-as long as the driver doesn't mind.
For added convenience, an "M" button on the steering wheel can be programmed from the iDrive interface to immediately set all the previously mentioned driving aids to the user's preference. The M mode can also be programmed so that the engine management uses the 507-bhp sport mode, which is not selectable with the power button. With the push of just one button, the M5 is tuned to exactly how the driver likes it.All this attention to the buttons isn't just a show-and-tell. M GmbH really went out of its way to create a driver-centric car with customizable variability in all pertinent driving aids. At its most relaxed setting, the M5 can drive like a very fast 545i, without the overly soft controls. At its extreme, the M5 sits it in a class of its own. Few cars come to mind that have this level of useful performance packaged into a mid-size four-door luxury sedan.Starting the V10 immediately brought out the second best part of this car: the sounds. Until now, I thought BMW's current V8 mill was one of the best sounding engines out there: Both lumpy and refined at idle while taking on new character with added revs and load.
With the V10 and its accompanying exhaust, the aforementioned lumpiness is gone due to increased overlapping of combustion events. The sound is more refined while just as brutish with the added extra cylinders. Piped through the dual exhaust, the tone is ever-present yet is never annoying or intrusive. The V10 turned my ear into the most sensitive throttle-position sensor, with every minute movement-intentional or not-communicated acoustically. The sound never droned or became tiring, even after an entire day of driving in traffic, at the track and on the autobahn. It's sounds nothing like Porsche's raspy race-car like V10.
The V10, designated as the S85 B50, was also designed from the ground up by M division for use in the M5. Though some variant of the block might trickle down to other non-M vehicles, it was solely designed with M performance in mind.
The 90 aluminum alloy V10 displaces only 58 cu in. more than the previous M5 V8, but produces 113 more bhp and winds up to 8250 rpm. The peak 507 bhp occurs at 7750 rpm.
