The new Alpina B5 biturbo Saloon and Touring models have been revealed by the legendary BMW tuners. In short, the latest update brings forward the performance enhancements previously featured on the limited-run Edition 50 model.

Just 50 units of the Edition 50 were made available back in March this year, but now, all Alpina B5 cars will get the higher-tuned 4.4 litre V8 biturbo engine that makes 600 hp and 800 Nm of torque – improving on the previous B5’s 540 hp and 730 Nm.

Performance figures for the new B5 include a century sprint time of 4.2 seconds and a top speed of 328 km/h. Alpina also claims that its Saloon model is capable of returning a fuel consumption figure of 9.5 litres per 100 km – the Touring does 9.6 litres/100 km. An adapted version of the F10 5 Series’s ZF-sourced eight-speed sport automatic transmission is standard.

Other performance enhancements are near-identical to what we saw on the Edition 50, highlights of which include a new sports suspension with active damping, an active roll stabilisation system, and a standard-fitted limited-slip differential hand-made by Drexler Motorsport. There is also an optional Akrapovic titanium exhaust system that weighs 17 kg less than the standard stainless steel system.

Exterior styling of the new Alpina B5 is very similar to what we saw on the Edition 50 model. The new 20-inch multi-spoke alloy wheels are a key feature among the usual Alpina exterior styling mods.

Inside, where the Edition 50’s seats were black with Forest Green quilting, the updated Alpina B5 models get full Merino leather upholstery. There is also a leather-covered instrument panel and Alpina piano-black interior trim. Customers may of course specify their Alpinas with the extensive options made available by BMW and BMW Individual.

Like all Alpina models, the B5 biturbo comes with BMW’s two-year factory warranty, and will be priced from 108,600 euros (RM494,594) for the Saloon, and 119,900 euros (RM546,057) for the Touring.
