The new Alpina D3 Bi-Turbo saloon and estate was introduced at the Frankfurt Motor Show. The BMW 3-series-based D3 Bi-Turbo is powered by the same twin-turbo 3.0-litre straight-six diesel engine used by the XD3 and D5 models. This engine can deliver 345bhp and 516lb ft. This marks the first time for Alpina to install a six-cylinder diesel engine on the D3.
A four-cylinder engine powered the new D3’s predecessor in 2005. This remains the top-selling model throughout Alpina’s history. A total of over 2000 units were sold. The engine, which is EU6-compliant, offers a combined economy of 53.3mpg and can emit 139g/km of CO2. The vehicle can sprint from zero to 62mph in 4.6sec and can reach a top speed of 173mph.
As a result, the new diesel saloon can outpace the BMW M135i, which can accelerate from zero to 62mph in 4.9sec and has a limited top speed of 155mph. The D3 Bi-Turbo is offered in both saloon and estate (Touring) bodystyles. Meanwhile, right-hand drive models are offered with standard rear-wheel drive. All-wheel drive is offered as an option for left-hand drive vehicles.
A limited-slip differential is optional. Among the styling revisions that the D3 received over the 3-series are a bodykit and the installation of a set of 19-inch Alpina Classic alloy wheels as standard equipment. Offered as an option are a set of 20 inches alloy wheels. The new D3 is expected to arrive in the UK in early 2014. The pricing has not been divulged yet.
