Alpina B4:
The Alpina B4 and Alpina D4 are high-performance compact executive cars manufactured by the German automobile manufacturer, Alpina. Based on the BMW 4 Series, the B4 and D4 are manufactured in coupé and convertible body styles. The first generation B4 and D4 were launched in 2014 and the more powerful B4 S was launched in 2017.
Introduced at the 2013 Tokyo Motor Show, the B4 is based on the outgoing 435i. The N55 straight-six engine was modified by using twin-turbochargers, a 61 percent larger intercooler and a new crankshaft. The engine also utilized new pistons; all of these modifications allow the engine to generate 408 PS between 5,550 and 6,250 rpm and 601 N⋅m between 3,000 and 4,000 rpm. The engine is mated to a ZF 8HP70 "Touch tronic" paddle shift automatic transmission, with no manual transmission options available. The transmission was modified to provide better shift timing. There were options for either a rear-wheel-drive or all-wheel-drive drivetrain.
