electronic stability program (esp®). esp® sensors detect when your fortwo is about to swerve, and instantly applies the brakes to individual wheels and adjusts engine power to stabilize the car. The smart fortwo is the only micro-compact car to offer this system as a standard feature.

abs with electronic brake-force distribution. abs prevents wheel lockup during emergency braking, enabling you to properly steer your smart fortwo, even on wet or snow-covered roads. An integral part of abs, electronic brake-force distribution balances the braking forces between the front and rear axle to prevent either end from locking.

Cornering Brake Control (CBC). The load on your wheels varies greatly during hard cornering. CBC improves vehicle stability by applying the most effective brake pressure to each wheel, allowing you to maintain control of the vehicle.

brake assist (bas) In an emergency, Brake Assist senses panic stopping by the speed at which you depress the brake pedal and automatically applies all available braking boost immediately. By helping to eliminate the delay caused by human nature, Brake Assist can potentially reduce stopping distances when it matters most.

Acceleration skid control. In slippery conditions where the drive wheels could start spinning, acceleration skid control brakes the wheel most at risk to avoid loss of traction. Power can then be re-directed to another wheel with more traction, a function similar to that of a differential lock. Meanwhile, engine torque control prevents instability when downshifting on slippery roads by a slight, automatic acceleration or disengaging of the clutch.

Hill holder. With the fortwo’s hill holder functionality, you'll never have to apply the handbrake again when pulling away on a slope. After lifting your foot from the brake pedal, the wheels remain braked for 0.7 seconds giving you more than enough time to move your foot to the accelerator without rolling backwards.
