In June 1996, the 2.0L 4-cylinder engine was fitted with a new intake camshaft with variable valve timing, which had previously been used in other gasoline engines. Rated power and maximum torque remained unchanged, however, an improved torque curve provided easier starting, better throttle response and traction.
The 2.3L displacement engine was derived from the time-tested 2.2L unit. The increase in displacement was intended to increase torque, not power. Increasing the compression ratio to 10.2 units. and by improving the geometry of the combustion chamber, fuel consumption, exhaust emissions and combustion noise have been optimized. The 2-litre engine has the same compression ratio and the combustion chamber has also been optimized. The E-200 and E-230 engines are equipped with an upgraded fuel injection system with an HFM engine management system and a scroll air flow sensor instead of the previously used P-motronic.
