Back with a vengeance.

It’s been just over a year since BMW introduced the sixth-generation of 5-Series, which means automotive enthusiasts all over the world have been eagerly waiting for that distinguished “M” badge to adorn the rear trunklid of the executive sedan. After many months of speculation, spy shots, rumors, and that 2012 M5 Concept teaser, BMW has finally unveiled the fifth generation of the M5 family tree.

The new BMW M5 is all about efficient power. The award-winning S85B50 5.0-liter V-10 used in the M5 and M6 is now gone, replaced with a twin-turbo V-8 with better emissions and fuel economy. And here’s one that will really get enthusiasts riled up – the new M5 will come standard with a double-clutch transmission! But, much of the M’s character still remains. Power is still sent to the rear wheels, handling is precise, those exclusive M aesthetics and trim are present, and it is still a track star with an executive appeal.

Efficient Dynamics is the name of the game at BMW today, and the new twin-turbocharged 4.4-liter V-8 is a shining example of the new mindset. Through the use of turbocharging, direct injection, and Valvetronic valve control, the new engine decreases fuel consumption and carbon dioxide emissions by over 30 percent while upping horsepower output by 10 percent and torque by 30 percent over the previous V-10 powerplant. Two twin-scroll turbochargers are positioned between the “V” of the cylinder banks to provide immediate power without lag, and force-feed the eight-cylinder with up to 1.5 BAR (21.76 PSI) of boost. This also helps the engine achieve its maximum torque output of 502 lb-ft. (680 Nm) from just 1,500 RPM all the way to 5,750 RPM. The 4.4-liter is the most powerful engine fitted into a production BMW by the M-Division to date. A total of 560 (412 kW) horses are on tap from 6,000 to 7,000 RPM.

This immense power is sent through a standard seven-speed M double-clutch transmission to the rear wheels. The DCT can be switched between automatic (D) and manual (S) mode, with the latter allowing the driver to switch gears by using the steering wheel mounted shift paddles or the M gear selector. Each mode can be custom-tailored by the driver to shift differently depending on the driving style, whether it is efficient or dynamic. An active M-differential with electronically controlled multi-plate helps to achieve optimal traction. Along with Dynamic Stability Control (DSC) the system can work to adjust the degree of lock between 0 and 100 percent within a fraction of a second.

The new BMW F10 M5 offers stunning performance even though it is more efficient than the previous model. Acceleration to 62 mph takes just 4.4 seconds, 124 mph is shattered in 13 flat, and top speed is an electronically limited 155 mph (250 km/h); or 190 mph (305 km/h) if equipped with the M Driver’s Package.

The chassis is also exclusive to the M5. New adjustments and upgrades have been made to produce a more driver-oriented and dynamic experience. Both the front and rear suspension feature new lightweight M-specific axle kinematics for better handling along with electronically controlled Dynamic Damper Control that can automatically adjust in any driving condition. New high-performance compound brakes with six-piston calipers reduce fade under track conditions. Standard on the 2012 BMW M5 are new M-specific light alloy 19-inch wheels fitted with 265/40 R19 tires at the front and 295/40 R19 at the rear. Customers can also upgrade to lightweight 20-inch forged alloys as an option.

Just like the previous four models that came before, the new M5 features a number of distinct exterior upgrades. The front bumper is all new and now features large air intakes to feed the engine and brakes with cool air. All four fenders have been extended to accommodate the wider track, and create an athletic stance. The widened front fenders also feature new M “gills” with integrated indicator bars. The rear has been aerodynamically optimized with an integrated diffuser between the quad tailpipes and a subtle rear spoiler on the trunklid.

Inside the M5 is that same mix of sport and luxury that makes the sedan so special. A number of exclusive M-sport features and trim pieces are featured such as the instrument cluster with black-panel technology, M Sport seats, leather covered center console, Aluminum trace trim strips Anthracite headliner, and ambient lighting. Rich Merino leather comes standard and covers the entire seating and center console. Other standard features include BMW ConnectedDrive and an M-specific heads up display.

The new 2012 BMW F10 M5 is the fifth installment in the M5 model history. BMW has not released pricing and availability for the performance sedan, so stay tuned!
