The second generation A-Class, the W169, was officially presented at Mercedes’ Stuttgart factory on June 28, 2004 with availability in early September.
Seven types of motors are available: four petrol (gasoline) (A150, A170, A200, A200Turbo) and three diesel (160CDI, 180CDI, 200CDI), all being four-cylinder and having either 5 or 6 gears. A continuously variable transmission system called "Autotronic Constantly Variable Transmission" (CVT) is an optional feature.
The petrol A200 Turbo provides 193 hp and 280 Nm of torque (rotational force); the diesel A200 CDI has 140 hp and 300 Nm. It is estimated that the W169 engines provide a 40% increase in power and a 10% decrease in fuel consumption compared to W168 engines.
The most powerful model can take the car from a standstill to 100 km/h in 8.0 seconds, and has a top speed of 227 km/h.
The A-class optionally includes a "Light & Sight" package which includes bi-xenon HID headlamps with gas-discharge bulbs; cornering lights (main-beam headlamps at road junctions and tight corners); "Headlamp Assist, which automatically turns on the lights when needed; and a rain sensor that adjusts wiper speed depending on rainfall intensity.
