Get to the core of electronics with ECM Titanium

Lightness and agility: two features that make the small sized city cars a real object of desire for anyone looking for pure fun, even in the city jungle. Smart Brabus is the perfect embodiment of a vehicle that, despite its extremely compact dimensions, impresses with sporty qualities not only on the road.

The result of a good recalibration is boosted by the vehicle’s power-to-weight ratio, which, thanks to the electronic contribution of ECM Titanium, can be significant to increase performance by modifying the engine management parameters. The 900 and 1000 cc 3-cylinder turbocharged engines, which are equipped on the more extreme Smart ForTwo and ForFour fitted out by the well-known tuner Brabus, turn out to be a small performance phenomena thanks to their excellent starting base.

Make the Smart Brabus driving experience even more distinctive by working with precision and reliability on a targeted intervention aimed at satisfying your customer’s needs.
