ALPINA B4 GRAN COUPE
To create the B4, Alpina uses a modified example of the M4’s twin-turbo straight-six, with smaller turbos that spool up at lower revs. The result is more power than a standard M4 and way more torque than the full fat M4 Competition. There’s classic 20-spoke Alpina wheels and a fresh bodykit too. That hefty torque figure helps it feel warp speed quick and the recalibrated gearbox fits the B4’s relaxed-butrapid character.
