Hand Alpina a BMW and you know you’ll be in for a treat. What they’ve done this time around is take a regular, road-going BMW 440i and gave the 3.0-litre straight six engine a good, solid massage.
The stock output isn’t shabby by any measure, putting out 320 hp at 5,500 rpm and 447 Nm of torque from 1,380 to 5,000 rpm. Alpina’s version of the 440i packs 440 hp and 660 Nm of torque, and you can have it in three variants – Coupe RWD, Coupe AWD and Convertible RWD.
Power gains come courtesy of two Alpina-specific turbochargers, allowing the 4 Series to sprint from 0 to 100 km/h in just 4.2 seconds. Top speed is 306 km/h and isn’t electronically limited – thankfully. In comparison, the 440i manages the century sprint in 4.9 seconds and has a e-limited top speed of 250 km/h. Interestingly though, fuel consumption for the Alpina B4 S is significantly lower at 7.9 litres per 100km on the combined cycle, versus the 440i’s 9.4l/100km. The eight-speed automatic transmission has also been reprogrammed to cope with the gains.
Standard equipment on the Alpina is comprised of adaptive Alpina sports suspension, 20-inch classic Alpina wheels, Akrapovič stainless steele exhaust system with double-ended tail pipes, Alpina bodykit and high performance 18-inch brake system with blue Alpina callipers. Others like paintwork and interior trims are factory-fitted items, save for the floor mats.
If only Alpina is represented in Malaysia. Man, the things people would do to their Bimmers…
