A year and a half has passed since the last E63 M6 rolled off the production line. Now, the specs surrounding the all-new M6 have been released.

BMW’s new top-of-the-line, two-door coupe and convertible will be powered by the same 4.4-liter, twin-turbocharged V8 found in the 2012 F10 M5. The engine produces a peak output of 560 horsepower between 6,000-7000 rpm, eight more than the factory rated 552 horsepower found in the M5.  A maximum torque of 502 lb-ft is available from just 1,500 rpm, thanks in part to BMW’s TwinPower turbo technology with twin-scroll turbochargers. All this horsepower and low-end torque allows the M6 to accelerate from 0-62 miles per hour in 4.2 seconds, or 4.3 with the convertible. Top speed is electronically limited to 155 miles per hour (189 mph with M Driver’s Package).

Although being different in nearly every way when compared to the naturally-aspirated, 5.0-liter V10 found in the previous generation M6, the smaller displacement powerplant has many advantages, namely in its efficiency. While its V10 predecessor managed an abysmal EPA estimated 12 mpg city and 18 mpg highway, the addition of turbocharging, stop/start functions and other technologies have improved fuel economy dramatically. BMW estimates the vehicle will achieve up to 30 percent less fuel consumption than its V10 predecessor.

Besides the engine. the transmission has also been changed. The outgoing Sequential Manual Gearbox (SMG) has been replaced by the faster and more efficient M Double Clutch Transmission (DCT). Also incorporated is a launch control feature to help driver’s get off the line quicker, and with less loss of traction. No information regarding a traditional manual transmission option has been released.

As with all M vehicles, the chassis has been tuned to deliver greater road-handling and driving performance. M-specific dynamic damper control come standard, as well as DSC stability control and servotronic steering. Braking has been improved with a lightweight compound, high-performance braking system. For even greater stopping power carbon-ceramic brakes are available as an option. To keep weight down the M6 Coupe has a roof comprised of carbon fiber reinforced plastic (CFRP), much like that of the carbon fiber roof found on the current E92 M3 Coupe.

In addition to all of the power and performance numbers the M6 has all of the interior technology and gadgets found on a flagship model. Merino leather upholstery, carbon fiber interior trim and illuminated door sills, along with a host drivers aids such as high beam assist,  night vision with pedestrian recognition, lane change and departure warning.

No pricing has been announced. However, based on the previous generation expect the new M6 to have a base MSRP well in-excess of $100,000.

Lightweight BMW M3 CRT unveiled

Power to weight ratio in everything in racing. Less weight allows a vehicle to accelerate with less friction and drag, making it quicker and faster. Lowing the weight of a car also its improves, agility, responsiveness and overall handling. BMW Motorsport, established in 1972, has a long tradition of taking their regular street cars and creating lighter and more nimble versions. The past lightweight M3’s include the iconic 3.0 CSL as well as lightweight M3s developed for both the E36 and E46 chassis production runs.

This past weekend, in anticipation of the Nurburgring 24-hour race BMW M unveiled their latest slim and trim creation, the BMW M3 CRT (Carbon Racing Technology). Unfortunately for U.S customers the M3 CRT will only be available to those in the European market.

Unlike the two previous production lightweight M3’s, BMW M chose to use the E90 M3 four-door chassis as the basis for the M3 CRT. This M3 has trimmed down thanks to a substantial portion of carbon-fiber reinforced plastic (CFRP). The hood of the M3 CRT is made of CFRP, making it 50 percent lighter than the steel equivalent on the regular E90 M3. The innovative material is also used in the construction of the vehicles seats. The M3 CRT supports its passengers with bucket seats composed of recycled-paper honeycomb and an exterior covering of CFRP. The final spots where CFRP is utilized is on a portion of the front lip used to channel air, and on the rear spoiler. All of these weight reductions allow the M3 CRT to have an unladen weight that is 99 lbs less than the standard M3 sedan. According to BMW, if you take into account the interior changes the weight savings total 154 lbs.

In accordance with the rest of the vehicle BMW Motorsport has placed a special, enlarged version of the naturally-aspirated V8 power plant in the M3 CRT. The engine, which can also be found on the M3 GTS, has been increased from 4.0-liters to 4.4-liters. Both horsepower and torque have also been increased because of this. At its peak the 4.4-liter punches out 450 hp at 8,300 rpm, with the maximum torque of 324 lb-ft ready to go at 3,750 rpm. All 67 units of the M3 CRT feature the seven-speed M double-clutch transmission (DCT) with launch control. The added horsepower combined with the reduction in weight give the M3 CRT a power-to-weight ratio of 7.7 lbs per horsepower.

The M3 CRT only comes in one color, BMW Individual Frozen Polar Silver metallic with Melbourne Red accents on the side kidney grills and hood vents. The interior offers the same individual touches with special aluminum grain on the door panels and trim pieces. Rounding out the interior is an Alcantara-covered M steering wheel, and special Sakhir Orange and Black two-tone design that covers the lightweight bucket seats.

If you yearn for something more aggressive and powerful, go for the Mini S coupe. The S coupe features a boosted 1.6-liter, four-cylinder gasoline engine with twin-scroll turbocharger, direct injection and fully variable valve management.
