Just prior to the BMW M4 Coupe’s official public unveiling at the upcoming Detroit Motor Show 2014, the car has been spotted cruising Detroit’s cold, wintery streets!
Under the hood, both the new M3 sedan and M4 coupe are fitted with a twin-turbocharged six-cylinder engine revving to 7,600 rpm and producing an impressive 431 hp between 5,390 rpm and 7,000 rpm and 406 lb-ft of torque from a low 1,800 rpm to 5,390rpm. That torque figure is available across a broad rev range and is an improvement over the outgoing BMW E92 M3 of 40 per cent. As a result of this brand new powerplant, both the 2014 BMW M3 and 2014 BMW M4 will sprint to 100 km/h from a standstill in just 4.1 seconds which equipped with the optional seven-speed M double clutch transmission. Top speed is limited to 250 km/h but this can be increased to 280 km/h with the optional M driver’s package.
In addition to this increase in power and torque, both new models weigh around 80 kg less than a comparably equipped predecessor model. As a result, the BMW M4 Coupe tips the scales at 1,497 kg while the M3 Sedan stands at 1,520 kg in base specification. These weight savings have been achieved through the extensive use of carbon fiber reinforced plastic as well as a carbon fiber roof and aluminium chassis and body components.
Thankfully for the real enthusiasts out there, both the new M3 and M4 are available with six-speed manual transmissions complete with throttle blipping. The new manual gearbox is 12 kg lighter than its predecessor and blips the throttle on downshifts which was previously only a feature on the M double clutch transmission. Following on from recent developments in the auto industry, both the new M3 and M4 come standard with electric power steering rather than a traditional hydraulic system. The new electric steering features three different options. These are comfort, sport and sport+.
