2014 Geneva Motor Show LIVE: BMW M3/M4 image

We saw online how they look like since December last year, but the hotly anticipated M3/M4 couple needs to be seen with your own eyes, felt with your hands and eventually throttled with your racing sneakers.

So, the Geneva auto show was a great venue for the public to see the powerful duo, which holds its best in the segment from BMW – while the 3 Series sedan was released some time before the 4 Series, the M versions were held off until they could be jointly released.

The performance duo unleashes from under their hoods a beautiful sounding and high-revving inline-six 3.0-liter engine with TwinPower Turbo technology. The gasoline sipping “monster” is capable of delivering 431 hp (317 kW) and a maximum torque of 406 lb-ft (550 Nm).

I’m really not sure if anyone cares, besides the EU regulators that like CO2 limits (we know they are actually necessary, but they sometimes are really annoying), but according to BMW and because the M3 is also 80 kg lighter, it’s now 25 % more fuel-efficient than the late M3 – at 8.8 liters/100 km with the manual transmission or 8.3 liters with the DCT automatic.

Speaking of transmissions, the six-speed manual allows the duo to reach 100 km/h in 4.3 seconds, while the more efficient optional 7-speed M DCT automatic is faster at 4.1 seconds. For both models the top speed is the usual affair – electronically limited to 155 mph (250 km/h); but if you go into your pocket deeper you can opt for the M Driver’s Package which lets you reach 174 mph (280 km/h).
