New Alpina B5 Bi-Turbo Based on 2011 5-Series Coming to Goodwood

Independent BMW customizer Alpina has published the first official sketch of its upcoming B5 Bi-Turbo ahead of the sports saloon world premiere at next month's 'Goodwood Festival of Speed' event in the UK.

As the car's name suggests, the B5 Bi-Turbo is based on the new 2011 BMW 5-Series sedan. So far, Alpina is keeping a tight lid on details about the car, but if the company's previous and current models are anything to go by, then the B5 Bi-Turbo could be all the M5 you'll ever want.

We wouldn't be surprised if the new B5 uses the same twin-turbocharged 4.4-liter V8 engine with an output of 500-horsepower and a hefty 516 lb-ft (700Nm) of torque found under the bonnet of Alpina's 7-Series B7 Bi-Turbo.

Engine aside, the sketch shows that the B5 will be mildly dressed up with a new body kit comprising of a front lip spoiler and rocker panels, as well a set of larger multispoke wheels. Interior upgrades also expected to be part of the package.

New BMW Alpina B3 S Bi-Turbo with 400 Ponies Available for Order in the UK

Following its recent world premiere at the Geneva Motor Show in March, the new BMW 335i-based Alpina B3 S Bi-Turbo is now available for order in the UK with first deliveries to start in July.

Offered in four-door saloon, Touring, Coupe and hardtop Convertible forms, the new B3 S comes with a modified 3.0-liter twin-turbocharged straight six upgraded to deliver a hefty 400HP at 6,000 rpm and 540Nm or 398.3 lb-ft of peak torque.

The 0-62mph (100km/h) sprint takes 4.7 seconds for both the saloon and coupe models which are also capable of achieving a top speed of 186mph or 300km/.

Alpina's take on the 335i range is identified on the outside by a redesigned front spoiler, a new rear diffuser which encloses the tailpipes and a different set of alloy wheels. The BMWs interiors are upgraded with a new steering wheel and modified instruments while Alpina also offers various lather trim options.

Prices for the Alpina B3 S Bi-Turbo start from £49,250 on-the-road for the sedan version.
