The BMW Alpina B5 Bi-Turbo Touring comes with all-aluminium V8 powerplant produces 507 horsepower (373 kW) at a moderate 5,500rpm, with maximum torque of 700Nm from 3,000 to 4,750rpm. “Bi-Turbo” refers to two turbo-chargers configured in parallel, each feeding one of the two cylinder banks. Specially developed large diameter exhaust-turbines allow this engine configuration to provide both exceptional power output and an abundance of torque over an especially broad rpm range while maintaining excellent throttle response at low rpm.
The intelligent coupling of state-of-the-art engine and transmission technologies give the BMW ALPINA B5 Bi-Turbo stunning performance figures: just 4.7 (Touring: 4.8) seconds from 0-100km/h / 0-62mph are needed, on the way up to a top speed of 307km/h / 191mph (Touring: 303km/h / 188mph). Massive braking capability in the form of ventilated high-performance brakes (front: 374mm/14.7in, rear 345mm/14.6in) ensures braking on par with pure-bred sports cars.
Together with 20″ wheels and tyres this yields a very balanced and direct chassis set-up, discarding a pure sport-orientated approach for an agile suspension with precise turn-in. Mounted on the light-weight 20″ ALPINA CLASSIC wheels are non-run-flat MICHLIN PILOT SUPER SPORT tyres measuring 255/35 ZR20 front and 285/30 ZR20 rear. Representing the latest in ultra-high performance tyre technology available today, they feature a running surface is made up of 2/3rds soft compound (centre) and 1/3rd hard compound (outside and flanks). This mixture makes for excellent durability despite typical hard use in high-performance vehicles yet provides very good grip in the wet. Enhanced tread stability and a new flank reinforcement technology ensures the tyre is less likely to suffer from spikes in temperature with a resulting loss of grip in the dry.
