The new Alpina B4 Biturbo has again been spotted at the Nurburgring.
This latest test model was seen parked outside BMW's test centre, which is based at the circuit.
The Alpina B4 Biturbo — Alpina's answer to the BMW 4-series — is likely to share its mechanical package with the new B3 Biturbo, with power coming from a twin-turbo straight-six engine with 404bhp and 443lb ft.
The B4 is tipped to be launched at the Geneva motor show in March before reaching the UK next summer.
Meanwhile, the B6 Gran Coupe has also been spotted testing, having been revealed at the Frankfurt motor show. However, this 532bhp twin-turbo 4.4-litre V8-powered model is not destined for sale in the UK because it will be built in left-hand drive only.
Autocar recently drove the new Alpina B6 Biturbo in regular coupé form, finding it to be a powerful and competent high-speed cruiser.
