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. The car has three driving modes "Comfort", "Sport" and "Sport +", which depend on the tweaking of the power delivered by the engine and suspension system settings according to the driving conditions....(Read more on Wikipedia)

Rating 5 stars

Performance Verdict

The 3.0-liter twin-turbo engine delivers exhilarating performance with 495 Hp and 730 Nm of torque, propelling the B4 from 0-100 km/h in just 3.7 seconds. Its power delivery is smooth yet relentless, perfectly matched with the SWITCH-TRONIC gearbox and AWD for exceptional traction.

Fuel Economy

For a high-performance grand tourer, the combined fuel consumption of 9.8 l/100 km (WLTP 10.1 l/100 km) is respectable. While not class-leading, it's a fair trade-off for the immense power and performance on offer, especially on longer highway cruises.
