The All New 2011 BMW 1 Series M Coupe. The new BMW 1 Series M Coupe has been developed for near-perfect balance and a large, square footprint. It is 71 inches (1803mm) wide – 4.8 inches (122mm) wider than its 1988 M3 ancestor – yet only 1.3 inches (33mm) longer at 172.4 inches (4379mm) long. The new BMW 1 Series M Coupe weighs in at 1,495kg DIN (3,296 lbs, preliminary), and features a 104.7-inch (2659mm) wheelbase, three inches longer than the 1988 M3. Front and rear track widths are exactly the same on the BMW 1 Series M Coupe at 60.7 inches (1542mm) each. Compared to the 2011 BMW 135i Coupe, the BMW 1 Series M Coupe is 0.2 inches (5mm) longer, 2.1 inches (53mm) wider, 0.5 inches (13mm) taller, and rides on the same 104.7 inch (2659mm) wheelbase. It features a track 2.8 inches (71mm) wider up front and 1.8 inches (46mm) wider in the rear, and weighs 35kg DIN (77 lbs, preliminary) less.
The new 2011 BMW 1 Series M Coupe features a high-strength steel unibody, with unique, widened fenders and rear quarter panels to house the substantially widened track. It also features a metal roof panel which saves about 35 lbs (15kg) compared to BMW 1 Series models equipped with a moonroof. The 2011 BMW 1 Series M Coupe, constructed as one of BMW’s most performance-oriented vehicles in recent years, will not be offered with a moonroof. This weight savings – at the tallest point of the vehicle – provides a corresponding drop in the center of gravity, which contributes to improved driving dynamics. It also helps maximize head room (or helmet room, as the case may be).
The All New BMW 1 Series M Coupe is equipped with the M-specific, light-alloy cross-spoke wheels from the M3 Competition Package and limited-production M3 GTS. They measure 19 x 9 inches with 245/35/R19 low-profile tires at the front and 19 x 10 inches with 265/35/R19 tires at the rear, and are silver in color.
In the 2011 BMW 1 Series M Coupe, power transmission to the rear wheels also provides the ideal basis for thrilling driving dynamics due to the consistent separation of drivetrain and steering functions. The rack-and-pinion steering is fitted with the hydraulic power steering system called Servotronic, which regulates boost in relation to road speed.
