Consisting of a plug-and-play module for the electronics, the confusingly badged B35 gains an extra 33kW and 60Nm from its M260 2.0-litre turbocharged engine, boasting total output of 261kW and 460Nm. It comes courtesy of increased boost pressure and high-performance injection and ignition mapping.
If that is not enough, Brabus also has the PowerXtra + tune which adds a stainless steel rear muffler into the mix, yielding another 11kW in the process to take the B35 S to 272kW – just 13kW down on the base A45 from the factory. Century sprint is taken care of in just 4.4 seconds, while top speed remains electronically limited to 250km/h.
For those not chasing extra oomph, the exhaust system can be fitted with either the stock tips or special steel and carbon fibre finishers designed to fit the standard bumpers.
Similarly, customers can specify the aerodynamics modifications made from high-quality polyurethane for an extra dose of attitude without the PowerXtra tuning kit.
It includes the two-piece front spoilers that are designed to reduce lift at speed, front air intake extensions that channel air into the side inlets more efficiently, and prominent roof-mounted spoiler to improve the aerodynamic balance of the car.
The car shown here also wears a set of 19-inch Monoblock T alloy wheels with black carbon inserts and wrapped in Pirelli P Zero tyres.
Inside, the interior can be jazzed up with backlit stainless steel scuff plates, aluminium pedals, branded velour floor mats and Brabus race aluminium paddles for the AMG Speedshift seven-speed twin-clutch gearbox.
Finally, Brabus will reupholster the seats in Brabus Mastik leather and Alcantara if you have your cheque book ready.
