BMW 3 Series Diesel and X3 Crossovers Become Moderate Hybrids


Starting this spring, BMW 3 Series diesel engines, as well as X3 and X4 crossovers, will be equipped with a moderate hybrid system by default. It will include a 48-volt starter-generator, which will help the engine during acceleration, and will also replace the start-stop system.

Moderate hybrids will be BMW 320d, 320d xDrive sedans and station wagons, X3 xDrive20d and X4 xDrive20d crossovers – all will be equipped with an 11-horsepower starter generator and a 48-volt traction battery. The electric motor will allow for a small increase in power during sharp accelerations and will provide more frequent engine operation in an optimized load range. The functions of the “start-stop” system are assigned to it: the starter-generator will stop the engine during braking (if the speed drops below 15 kilometers per hour) or when coasting (up to 160 kilometers per hour).

The fuel consumption of the hybrid BMW 320d is 4–4.1 liters per 100 kilometers, 320d xDrive – 4.2–4.3 liters, and the X3 xDrive20d and X4 xDrive20d – 4.8–5.1 liters. That is, on average, car efficiency will improve by 0.5 percent.

Also in the spring in the BMW 3 Series lineup there will be a new budget version with the index 318i. Such cars will be equipped with a two-liter turbo engine with a return of 156 horsepower (250 Nm) and an eight-speed Steptronic automatic. From zero to hundreds, the BMW 318i sedan can accelerate in 8.4 seconds, the station wagon in 8.7 seconds. The maximum speed is 223 and 220 kilometers per hour, respectively.
