In 2004 Mercedes-Benz faced customers complaints that its Sensotronic brake-by-wire system - which used an electrical link to control vehicles' brake pads - sometimes failed.
Both cars can be equipped with optional torque vectoring, a brake-based system built to augment the mechanically locking rear differential and help put power to the ground.

The large wheels also create the necessary space for installing the BRABUS high-performance brake system with 12-piston aluminum fixed calipers and 380 x 36-mm (15.0 x 1.42 inches) vented and cross-drilled discs in front, and 355 x 28-mm (14.0 x 1.1 inches) discs and six-piston aluminum fixed calipers on the rear axle.
Stanley invented a double-brake system using two brake shoes supported by springs that clamp down on a disc.
The system allows a 1.6kWh lithium-ion battery pack, mounted behind the seats for weight distribution reasons, to be charged through a rear axle electro-hydraulic brake energy regeneration system.
Indeed, the prototype has a distance-keeping system that will brake to a standstill, and move off again when the car in front moves.
The computer-control system can then apply the brake on the wheel concerned, and even adjust the amount of engine torque sent to that wheel, so that skidding is prevented.
Both drugs turn off a natural brake on immune system activity called CTLA4 (cytotoxic T-lymphocyte antigen 4).
In addition, Mercedes-Benz has already equipped this innovative electric car with the radar-based collision warning system COLLISION PREVENTION ASSIST with adaptive Brake Assist as standard.

Honda's Collision Mitigation Brake System (CMS), for example, uses a forward-looking millimetre-wave radar to scan the road ahead.
In addition to the aforementioned traction-control system, standard features include ABS brakes, electronic brake assistance, child safety locks and driver, passenger and side-head air bags.
