Besides its much lauded smoothness, the new Alpina B7 xDrive sedan impresses with its sharpened responsiveness and enhanced power delivery over the entire rpm range. Continuous developments and detailed improvements mean the combination of high torque output and a transmission with great dynamic capabilities results in improved driving performance over its predecessor.

The latest generation 4.4-liter V8 engine with two, twin-scroll turbochargers, direct injection and Valvetronic fully variable valve timing and Double-VANOS variable camshaft timing, delivers 600 hp and 590 lb-ft of torque.

The exhaust side of the turbochargers are equipped with a 54 mm (previously 50 mm) diameter impeller. Additionally, the Alpina-specific intercoolers feature an interconnection to equalize and reduce pressure pulsations between the two cylinder banks of the V8 engine. This, together with a new engine management software, means that the peak torque of 590 lb.-ft. is now available from only ,2000 rpm all the way up to 5,000 rpm (previously 3,000 - 5,000 rpm). This leads to significantly improved throttle response, more engaging power delivery and an effective performance gain in the most relevant rpm range.

The new Alpina B7 now accelerates from 0 to 60 mph in just 3.5 seconds (previously 3.6 seconds) and can reach a maximum speed of 205 mph (previously 194 mph).

All components of the Alpina high-performance cooling system are designed to remove inefficiencies and maximize effectiveness - special high-volume coolers are interconnected by large diameter piping for maximum throughput. The intercoolers comprise an indirect air to water to air set-up to facilitate short air intake paths. Combined with additional external water coolers and a transmission oil cooler, the system ensures the thermodynamic stability of the twin-turbocharged V8 engine at all times, even under highest loads and high ambient air temperatures.

The new Alpina B7 features the latest generation 8-Speed Sport Automatic Transmission from ZF (8HP76) with Alpina SWITCH-TRONIC. The transmission software has been thoroughly reworked by Alpina and adapted specifically to the performance characteristics of the new twin-turbocharged V8, offering exceptional driving comfort and performance in all situations.

Close gear ratios and a total spread of 7.81:1 results in high levels of shift comfort and efficiency. In Automatic Mode the combination of eight gears and high engine torque facilitate relaxed cruising at low engine rpm even when travelling at higher speeds. In Sport Mode, the shift times have been improved over the previous generation of B7 and are now considerably quicker.

Transmission components such as the torque converter with lock-up clutch and the planetary gear sets are reinforced and along with the inner transmission cooling are designed to cope with the high torque output of the twin-turbocharged V8 engine. This means that no torque reduction is necessary during upshifts.

The stainless steel Alpina sports exhaust system is responsible for a reduction in both back pressure and weight. Active exhaust valves allow the driver to change the sound experience by using the Driving Experience Control switch to select between Comfort and Sport Mode. In typical Alpina fashion: the two twin tailpipes of the exhaust system are integrated elegantly into the rear bumper.
