Alpina B6 Bi-Turbo Cabriolet Revealed Ahead of Frankfurt Debut With 507-HP
In many ways Alpina is to BMW as AMG is to Mercedes-Benz, and it looks like the B6 Bi-Turbo Cabriolet may gave some of AMG’s finest a run for their money. The sporty convertible BMW features a 4.4L twin-turbocharged V8 power plant with 507-hp and a neck-bending 516 lb-ft of torque. This gives the B6 an impressive 0-62 mph time of 4.8 seconds and a top speed of 193-mph. Best of all, the convertible can still get 21.6-mpg – not too shabby.
The B6 Bi-Turbo is a huge improvement over the factory BMW 650i, which features a 4.4L turbocharged V8 with 407-hp and 443 lb-ft of torque. In addition to the extra performance, Alpina also outfits the B6 with some carbon fiber styling pieces, Alpina’s trademark wheels, a front lip and rear spoiler. The interior also receives plenty of luxurious, bespoke upgrades.
Alpina also announced that the convertible model will shortly be followed up with a standard coupe version.
