The Volvo S40 comes with optional Active Bi-Xenon headlights which point the light beam in the direction of the road as it curves (standard in SE Lux models). There is also a camera which can be located on the side mirrors which alerts the drivers of passing vehicles beside the car. The camera is optional on all models. This is given the name BLIS (Blind Spot Information System). The S40 T5 (one of the several variants of the S40) features a 2.5 L (2521 cc) five-cylinder fuel-injected engine with a light-pressure turbocharger. The valvetrain has four valves per cylinder and is a DOHC design. The engine is transversely mounted at the front of the vehicle and drives the front wheels, as was with the first generation. The T5 engine got a performance increase of 9 hp (6.7 kW), giving an output of 227 hp (169 kW). The D5 engine has become available with a manual gearbox offering 400 N·m (300 ft·lbf) of torque and an automatic transmission offering 350 N·m (260 ft·lbf) by the second half of 2007.
