Spy photographers last snapped the 2022 BMW Alpina B4 Gran Coupe this summer and now the company has begun testing a more evolved prototype. Looking closer to the production model, the latest prototype has been equipped with an Alpina splitter and rear spoiler. We can also see a modified rear bumper with a four-tailpipe exhaust system.
Additional changes are limited, but the
model rides on five-spoke wheels that are backed up by a beefy braking system
with blue calipers. While it’s not visible, we can also expect a sport-tuned
suspension similar to the one found on the B3. The interior is barely visible,
but we can expect an assortment of changes including an Alpina-branded steering
wheel wrapped in hand-stitched Lavalina leather. It should be joined by Alpina
door sill plates and floor mats as well as a revised digital instrument cluster
with Alpina graphics.
The biggest changes will come under the
hood as the model is expected to have a turbocharged 3.0-liter six-cylinder
engine that produces 456 hp and 700 Nm of torque.
This enables the B3 to accelerate from 0-100 km/h in 3.8 seconds and
top out at 303 km/h.
Regardless of the final numbers, the B4
Gran Coupe should be significantly more powerful than the standard M440i xDrive
which has 382 hp and 500 Nm of torque. It allows
the car to run from 0-96 km/h in 4.4 seconds, before hitting a top
speed of up to 250 km/h.
