Mercedes-Benz apprentices tune-out a B-Class with a V8 producing 383 PS (378 bhp / 282 kW) and 530 Nm (391 lb-ft) of torque.

Don't get your hopes up just yet, this is only a one-off prototype.

A dozen Mercedes-Benz apprentices from the Daimler facility in Rastatt came up with this idea during their tenure there - namely, to fit a V8 engine under the bonnet of a B-Class.

The team of 12 started with a B200 CDI and then fitted it with a 5.5 liter E500 engine (the M273) that produces 383 PS (378 bhp / 282 kW) and 530 Nm (391 lb-ft) of torque. They coupled the power plant to Mercedes-Benz's 7-speed G-Tronic transmission.

The student engineers also took to converting the B-Class to rear-wheel drive by fitting it with the G-Tronic's drive shaft going into the rear axle from an old E430 (E-Class). The radical tuning job also consists of adding the proper safety systems - ABS, ASR and ESP - as well as limiting top speed to 250 km/h.

The B55 does the 0 to 100 km/h sprint in just 5.2 seconds.

The project took 8 months to come to fruition and the high-performance prototype of the B-Class can put to bed the best of the hot-hatches such as the Golf R.

The B55 is also outfitted with 18-inch AMG wheels and comes with an Alcantara and leather finish and sport leather seats.
