BMW M6

The BMW M6 is the high-performance variant of the German automaker's full-size 6-Series Coupe. As with the last-generation model, it combines corrupting power with a coddling interior, plenty of technology features and a fun-in-the-sun convertible experience.

Stylistically, the M6 builds on the standard 6-Series with a much more aggressive body kit and either 19-inch or optional 20-inch alloy wheels. Wider external air intakes and new LED corona rings and accents give it a menacing appearance, although the overall look is far more cohesive and elegant than that of the outgoing model.

Inside, unique sports seats should hold driver and passenger in place. M-specific features like the automaker's custom-tailored M Drive system and M Heads-Up display are also on board once again. Aside from numerous M badges, a unique three-spoke steering wheel and some minor trim differences, the cabin is otherwise standard 6-Series fare, meaning it features a driver-focused design and high-quality materials throughout.

M-style performance with a twist
The redesigned M6 - the third generation to bear the nameplate - ditches the naturally aspirated V10 of the old model in favor of a new twin-turbo 4.4-liter V8 that also does duty in the M5. Rated at 560 horsepower, the V8 is known to Bimmer-philes as the S63T due to its close relation to the S63 used in the X5 M and X6 M. Unlike high-revving BMW M engines of yore, the new V8 boasts its 500 lb-ft. of torque across an especially wide rev range (1,500 to 5,750 rpm). The engine's rev limiter is set at 7,200 rpm, which is 200 rpm higher than the S63 used in the crossovers, whereas the old V10 screamed its way up to a 8,250 rpm redline.

The V8 gets its grunt from two twin-scroll turbochargers positioned in the V "valley" between the two cylinder banks for a reverse-flow layout, which helps keep the engine especially compact and also yields a quicker warm-up of the similarly located catalysts. The turbochargers use a higher maximum boost in the M6 (21.7 psi) than in the crossovers with the standard S63 motor.

BMW says that the M6 can sprint to 62 mph in 4.2 seconds, but a 12.6-second sprint to 124 mph is even more impressive. Both models are limited to a 155 mph top speed.

Unlike the M5, which will offer a six-speed stick for North American consumers from launch, the M6 will initially be available only with BMW's dual clutch automatic unit, with the manual joining the options list in a year or two. With seven forward gears, the DCT offers sequential-style shifting from either the gear lever or a pair of paddles. Several drive modes are tailored for normal and sport-oriented driving, while a launch control system is on board for optimal 0-60 sprints. BMW's M Drive system lets the driver tailor six parameters to certain road conditions like tracks or highways.

Fuel economy for the dual clutch/V8 combo is 14 mpg in the city and 20 mpg on the highway.

Helping the M6 stick to the road is an Active M limited slip rear differential and an M-specific suspension setup. Special stability control and ABS tuning will allow for sportier maneuvers than the standard 6-Series offers, while large 15.7/15.6 (front/rear) brakes should bring things to a rapid halt. Carbon ceramic brakes are an optional extra.

Standard Equipment
Befitting its spot near the pinnacle of BMW's model range, the M6 comes lavishly equipped with standard leather upholstery, 20-way power adjustable and heated M sports seats, a navigation system with a 10.2-inch display and real-time traffic information, a rear parking camera and front and rear park distance control to make parking a snap, radar-based cruise control, a 12-speaker premium audio system with HD radio and an iPod adapter, dual-zone automatic climate control and a keyless entry and start system.

Highlights from the options list include a 16-speaker Bang & Olufsen sound system, ventilated seats, a night vision system and a heads-up display that transmits speed and other vital information to the base of the windshield. Also available is a Driver Assistance Package that bundles together a lane departure warning system, active blind spot detection, side and top view cameras and a speed limit info system that displays the posted speed limit in the instrument panel and heads-up display (if equipped).

Safety Equipment
Standard safety features on the M6 include dual front, side, side curtain and knee airbags in addition to active head restraints and traction and stability control systems.

BUGATTI VAYRON SUPER SRORT

It's all about the noise. How the mighty 1200-hp W-16 growls like a badly hungover grizzly bear when you punch the gas pedal. The psychotic calliope routine from the four turbochargers as you change gears, a cacophony of chuffs and puffs, whooshes and whistles right behind your head that sounds like you're about to be run over by the 20th Century Limited. And the white-noise roar of the wind over your head as you effortlessly blow through the 200-mph barrier, headed, like a ground-based Chuck Yeager, for the outer limits of road car performance. The Grand Sport Vitesse is the ultimate Bugatti Veyron experience, in shattering 7.1 surround sound.  In simple terms, the Vitesse is a Veyron Grand Sport convertible that's been given the Super Sport treatment. In addition to 1200 hp at 6400 rpm, its 8.0-liter W-16 delivers a herculean 1106 lb-ft of torque from 3000 to 5000 rpm, courtesy of the same bigger turbos and intercoolers as the Super Sport, and, because you need more fuel as well as more air to make more power, the same quad fuel pump setup. And boy, does this thing have an appetite: Bugatti engineer Jens Schulenburg claims that at full throttle the Super Sport/Vitesse engine will consume more air in one hour than a human does in a month, though that statistic is purely academic, because at full throttle the Vitesse's W-16 will gulp through an entire tank of gas -- 26.4 gallons -- in just eight minutes

But there are subtle differences between the Super Sport and the Vitesse. Removing the roof changes the way the air flows around the car, and in a car with the Veyron's V-max, that demands you pay attention to aerodynamic details. The real spoiler  , for example, knows whether the detachable hardtop is on or off the car, and so changes its angle of attack to ensure it delivers the same level of downforce at high speeds (with the roof off, the Vitesse is limited to a mere 233 mph; roof on, it will hit 255 mph). The rear differential oil cooler has been moved from the right-hand side of the car to under the rear diffuser, and the spring rates have been softened slightly to compensate for the reduction in body rigidity.  As you'd expect, the Grand Sport Vitesse is staggeringly fast -- in addition to its stratospheric top speed, Bugatti claims a 0-60 mph time of less than 2.6 seconds, and a quarter-mile time of 10.0 seconds. It says the Vitesse will reach 124 mph from a standstill in just 7.1 seconds, and 186 mph in 16.0 seconds. What does that feel like? Like a Nissan GT-R on LSD. While the GT-R's acceleration to 100 mph is impressive, the Bugatti maintains the same relentless thrust way beyond 200 mph. Nail the gas in the Vitesse at 160 mph in fifth, and it responds like a regular Corvette or Porsche 911 might at 60 mph in third gear. It's truly, truly staggering. Especially for a car that weighs almost 4400 pounds. Simply put, the Vitesse alters the way you perceive the world. See a straight on any regular road, think of a number, and double it. That's the speed at which the Vitesse will be traveling when it arrives at the next corner. And that's no problem, because you simply hammer the carbon-ceramic brakes and the Vitesse stops. Just like that.  First will take you to 65 mph, second to 92 mph, and third to 122 mph, so the Bugatti will simply annihilate regular traffic, shrinking safe passing zones to absurdly small parcels of space and time. Push hard through the twisties, and the handling devolves into mild understeer; the trick to canyon road cut-and-thrust in this car is to be just a little patient with the gas, and feed it in as you exit the turn. Get it right and you can feel a subtle change in the weighting of the steering as the Haldex system funnels more torque to the rear tires, and you know you've nailed it when you sense the massive 365-710 ZR 540A Michelins nibbling at the limits of adhesion as you power away from the apex. Attacking a series of fast, open sweepers in the Vitesse is almost a religious experience.

At normal speeds -- mooching through town, or cruising on the freeway -- the Bugatti has the same easy drivability of the GT-R; in fact, it feels smoother and more refined than the edgy Nissan. The Veyron's seven-speed dual clutch automated manual transmission -- developed and built by British engineering company Ricardo -- is more accomplished, and the ride is more compliant. And that's the utter genius of the Grand Sport Vitesse: For all its staggering power and performance, it's no hairshirt hypercar. You don't have to wrestle it into submission to drive it fast, and grit your teeth when you drive it slow. You can go 200 mph with the roof off without mussing your hair, and you can crawl at 2 mph in summer traffic along the Boulevard de la Croisettes in Cannes in air-conditioned comfort. There are some who suggest that because the Bugatti Veyron is so user-friendly it is somehow less of a car. They're wrong. The Veyron is extraordinary, in every way. And the Grand Sport Vitesse might be the most extraordinary Veyron of them all.

How Fast Can a Veyron Go?  Former racer Pierre-Henri Raphanel, Bugatti's official test driver and quite possibly the world's bravest man, says the only thing preventing the Veyron from going beyond 270 mph is tires. Raphanel, who set a production car record top speed of 268 mph in a Veyron Super Sport at VW's Ehra-Lessien test track in July, 2010, says Michelin runs the Veyron's massive meats on its tire test dyno at 270 mph -- the fastest it can spin -- for 20 seconds, then at 250 mph for 20 seconds. It repeats that cycle two more times. Then the tires explode.  VW engineers made Raphanel run both directions along the 5.6-mile straight on the eastern side of the Ehra-Lessien track to get the record, because they knew the Super Sport's tires could not handle the g-loading on the gently curved western section at V-max. Michelin will only allow two sets of tires -- they cost about $42,000 a set -- be fitted to the Veyron before the rims -- $69,000 a set -- also have to be replaced to ensure the integrity of the bead seal at high speed. Tires are why the Grand Sport Vitesse's 255 mph top speed is artificially imposed, confirms engineer Jens Schulenberg. Engine power is not the problem: "We could go faster," he says. Gulp.
THE MOST EXPENSIVE CAR IN THE WORLD

LAMBORGHINI AVENTEDOR LP700-4

Concerns about weight - and most other rational thoughts - are extinguished once one experiences the Aventador's operatic and absurdly potent V12. Displacing 6.5 liters and boasting a lofty 8500 redline, this beast of a motor makes 691 horsepower and 509 lb-ft of torque at 5,500 rpm.

When you couple that much power with the car's Haldex all-wheel-drive system, what you get is a zero-to-62 mph time of just 2.9 seconds and a top speed of 217 mph. These figures put the Aventador proudly atop the Lamborghini range and easily in the company of the most impressive supercars in the world.

Fuel economy is likely the last thing on the mind of anyone considering a Lamborghini, but the automaker added two new technologies for the latest model year in the interests of efficiency and the environment.

The first, a start-stop system that shuts down the engine to save fuel at traffic lights or in stop-and-go traffic, is a supercapacitor-based system that's both lighter and faster to restart the motor than a traditional battery-based system. The second is a cylinder deactivation system that shuts down half of the V12's cylinders during light-throttle situations, temporarily turning the motor into a straight-six. When the driver lays into the throttle, the other six cylinders fire back up for full power.

Despite those technologies, there's only so much they can do to enhance the mileage of the inherently thirsty V12 - fuel economy is rated at 11 mpg in the city and 18 mpg on the highway.

Shifting duties are handled by a seven-speed single-clutch automated manual gearbox that Lamborghini refers to as a robotized Independent Shifting Rods (ISR) transmission. Capable of blasting from gear to gear in just 50 milliseconds, it can be a bit herky-jerky at low speeds and isn't as refined overall as the dual-clutch boxes used by some competitors. Lamborghini said it opted to use the ISR to save weight over a dual-clutch unit.

Helping transfer all 691 horsepower to the ground at all four corners are two different tires and wheel sizes - 255/35/R19 for front wheels and tires, with massive 335/30R20 wheels and tires for the rear. Stopping the big Lambo are 400x38m six-piston carbon ceramic brakes in the front, and 380x38mm carbon ceramic brakes in the rear.

Get the Aventador out to an empty, winding road, and the supercar will impress with its superb engine, accurate steering and excellent overall balance, though its girth prevents it from feeling truly nimble.

Standard tech is in
Standard features are quite extensive, including electronic control goodies such as ABS, EBD, ASR, ESC, a hill holder function, an electronically controlled rear spoiler, an electronically controlled side air intake system, servotronic and an integrated command with three different driving modes that integrate the gearbox, differential, engine response and servotronic simultaneously.

Interior and vehicle standard features include: Push to Start/Stop button, keyless ignition, full TFT displays in the cockpit, on-board computer, multimedia system with seven-inch display, iPod and USB interface, navigation, Bluetooth, bi-xenon headlights with washer, LED daytime running lights, automatic air conditioning with solar sensor, crepuscular and rain sensors and electrically adjustable and heated side mirrors with folding function.

Lamborghini also introduced a new suspension system uses pushrod technology, inspired by Formula 1 racing. It functions by locating the springs and dampers no on wheel mounts, but rather inboard to the body shell. The end result when coupled with the double wishbone suspension is precise handling in dynamic driving conditions, but almost luxury-like comfort when cruising.

Given the exotic nature of the Aventador, it is only fitting that Lamborghini decided to include a pair of new exterior colors: Metallic Grigio Estoque (a type of dark gray), and a pearl Arancio Argos orange. In addition to the two new colors, there will be three matte colors, including the white shown in Geneva, for a total of 13 exterior colors.

Key Competitors
Exotic sports cars don't usually get cross-shopped like mid-size sedans, but the Aventador can still be compared with the Ferrari 599GTB Fiorano, the Aston Martin DBS and the McLaren MP4-12C.
