Here's how to make the 4 Series even better, with no "M" badges required.
Alpina's relationship with BMW continues as strong as ever, as evidenced by the reveal of the new 4 Series-based Alpina B4 BiTurbo. Like all other Alpinas, this latest one combines an elegant series of exterior enhancements along with a dramatic power upgrade. There are now front and rear spoilers, a stainless steel twin-pipe exhaust system and other aerodynamic upgrades. Perhaps the most recognizable Alpina design trait are those large 20" twenty-spoke wheels. Power comes from a twin-turbo 3.0-liter six-cylinder that's good for 404 horsepower and 442 lb-ft of torque.
Mated to an eight-speed automatic, acceleration and performance, of course, are brisk. 0-60 mph takes just 4.2 seconds and it has a top speed of 190 mph, and yet it has an average US fuel economy of 31 mpg. To help handle that extra juice, Alpina added a sport-tuned suspension and high-performance brakes. Available in both rear- and all-wheel drive, the B4 Alpina doesn't come cheap. Set to go on sale in May, pricing starts at $77,975 for the RWD model and jumps to $81,270 for AWD.
