The 2016 BMW Alpina B5 Bi-Turbo’s 4.4-litre twin-turbocharged V8 engine produces 441 kW (600 hp) and 800 Nm of torque. It’s not just the more powerful engine that’s better than the BMW M5 – the 2016 BMW Alpina B5 Bi-Turbo is available in estate version too. So, although not directly from BMW M, the Mercedes-AMG C 63 Estate does have a tough rival.
The engine is mated to an 8-speed automatic transmission. Both Saloon and Touring versions hit 0-100 km/h in 4.2 seconds. The former can go up to 328 km/h, while the latter maxes out at 323 km/h. In the same order, the CO2 emissions figures are marked 221 g/km and 224 g/km respectively.
The 2016 Alpina B5 Bi-Turbo features a sports suspension setup with electronically adjustable dampers and active roll stabilization. Limited slip differential, Merino leather upholstery for the seats and Alpina Piano interior trim are standard. Those looking for a very sporty exhaust note can opt for a lightweight titanium exhaust system by Akrapovic. The custom exhaust system is 17 kg lighter than the stock unit. A high-performance fixed-caliper brake system is also in the options list.
The 2016 Alpina B5 Bi-Turbo are priced way higher than the BMW M5; the Saloon and Estate versions are priced at €108,600 and €111,900 respectively in Germany.
