Our spy photographers caught two new BMW models testing Europe. Neither the BMW 4 Series convertible nor the Alpina 6 Series Gran Coupe spotted here wear much camouflage tape, meaning these spy photos give us a clear look at both of the upcoming cars.
The BMW 4 Series convertible looks, unsurprisingly, just like the 4 Series coupe we have spied previously. BMW will start using even model numbers for all coupes and convertibles, so what would previously have been sold as the 3 Series coupe and convertible are now the 4 Series. The drop-top 4 Series features a power-folding hardtop that, when raised, closely mimics the shape of the coupe version. In the U.S., BMW will sell the 4 Series convertible as a 428i or 435i, with rear-wheel-drive only. Production begins in November.
We also got a look at an upcoming Euro-only Alpina-tweaked version of the 6 Series Gran Coupe. German tuner Alpina has already worked its magic on the 650i coupe and convertible, so it’s only logical that the company will extend its offerings to the four-door Gran Coupe body style. The modified car will clearly receive a new front fascia, larger wheels, and a new wing perched atop the trunk lid. Beneath the skin, we expect the Gran Coupe will receive the same B6 Bi-Turbo treatment as the two-door versions, which results in the twin-turbo 4.4-liter V-8 engine producing 540 hp and 516 lb-ft of torque.
Of course, drivers who want a faster version of the car could also select BMW’s own M6 Gran Coupe. Revealed at the Detroit auto show, the car packs the same 560-hp, 4.4-liter twin-turbo V-8 engine and seven-speed dual-clutch transmission as the M5 sedan.
