Updated Alpina B5, D5 S revealed
Alpina has refreshed its range of BMW 5 Series-based performance models – the petrol B5 and the diesel D5 S – to coincide with the base car's mid-life update. The updated models are set to go on sale in international markets in the coming months. The B5 and D5 S get the same range of chassis upgrades as before. This includes electronically controlled dampers, stiffer springs and upgraded brakes, with four-piston fixed calipers at the front and single-piston floating calipers at the rear.
The headline upgrade for the B5 over the outgoing model is a power boost. Based on the M550i, the 4.4-litre twin-turbo V8's power is now at 622hp, up from the old car's 608hp, with 800Nm of torque. That translates to a 0-100kph time of 3.4sec (3.6sec for the estate) and a 330kph top speed (322kph for the estate). The extra power comes from an ECU retune and an improved cooling system with enlarged intercoolers.
The Alpina D5 S also benefits from a power upgrade, rising from 326hp to 347hp partly thanks to the installation of a 48V mild hybrid system. Torque is up from 700Nm to 730Nm, too. Two-tenths are shaved off the 0-100kph time, down to 4.8sec, while a 275kph top speed results. The B5 features an electromechanical rear-wheel steering system, aimed at improving around-town manoeuvrability while also aiding high-speed stability. Touring models retain the self-levelling rear axle air suspension as the standard 5 Series.
The aesthetic changes reflect that of the 2020 5 Series, too, with front intakes enlarged by 40 percent to improve cooling, redesigned lights front and rear and a new rear bumper. The trademark multi-spoke Alpina wheels are retained, alongside quad tailpipes for both variants. Upgrades to the interior include a hand-stitched leather wheel and numbered plaque on the dashboard. The upgraded infotainment system features, as does a 12.3-inch digital instrument display with bespoke Alpina graphics.
While the Alpina models will not be available in Nepal, BMW is expected to launch the standard few Series facelift in Nepal in 2021.
