Renowned German auto tuners Alpina recently took to the floor at the Tokyo Motor Show to unveil their latest advanced BMW creation: the 2014 BMW Alpina B4 Bi-Turbo Coupe. Sporting Alpina’s adaptive sport suspension in conjunction with a Switch-Tronic-equipped 8-speed sport-automatic transmission, the B4 Bi-Turbo Coupe pairs a modern straight-six three-liter engine with a duo of turbochargers – thus creating 410 hp, 442 lb-ft of torque, acceleration from 0 to 62 mph in 4.2 seconds, and a top speed approaching 190 mph. Signature Alpina details include the likes of two elliptical double tailpipes and 20″ wheels, as well as a high-performance braking system that features 14.5″ discs up front and 13.5″ discs in back. Just as impressive as the high-powered, aerodynamic coupe’s exterior – and Lavalina leather-lined interior – is the tuned car’s fuel economy: the B4 is rated at about 31 mpg. Alpina’s B4 is slated to be available as early as May of 2014 starting at €57,647 EUR (approximately $78,102 USD).
