The Alpina F32 B4 Bi-Turbo Coupe has already been caught testing, ahead of a possible reveal next year.

About a month ago BMW introduced the all-new 4-Series Coupe which is scheduled to reach dealerships later this summer. As these spy photos show, Alpina is already testing its own version of the 3-Series Coupe replacement which should be unveiled next March at the 2014 Geneva Motor Show.

Although it's wearing the body of the regular 4-Series Coupe, we can tell this is an Alpina product judging by the quad exhaust setup, blue brake calipers and the typical large Alpina wheels. An all-wheel drive setup will be available, while top speed should be beyond the 186 mph (300 km/h) mark.
