With 190 hp and 400 Nm, the 320d is no match for the 330e in terms of power and performance. The latter combines a 184 hp and 300 Nm two-litre petrol engine with a gearbox-integrated 68 hp electric motor, which can boost its power temporarily to 113 hp. The total system output equals 293 hp and 420 Nm. A manual gearbox is not available, but that's not a problem when you know that the 8-speed ZF unit is a fantastic companion.
The performance of the 330e is remarkable. It accelerates to 100 km/h in just 5.9 seconds (6.8 seconds for the 320d) and reaches a top speed of 230 km/h. It goes almost as vigorously as a sports car, were it not for the fact that the nearly 300 additional kilos of the 12 kWh battery (1,740 kg total weight) drag the car down, without however spoiling the fine balance and pleasant steering.
