Rule of thumb: The generally accepted rule is that diesel is worthwhile for people who drive a lot, and that anyone else should choose a gasoline-driven car. After all, a diesel-powered car consumes up to 25 percent less fuel, but gasoline-powered cars are often cheaper in terms of purchase price, insurance, and running costs. In Germany, depending on the model, a diesel-powered car will be worth the extra investment if annual mileage exceeds 15,000 kilometers.
Both powertrains have their strengths: When deciding which powertrain to choose, however, drivers should consider more than just annual mileage: “Both powertrains have their strengths in different vehicle classes. A modern gasoline powertrain makes even affordable compact cars efficient, while an advanced diesel powertrain can keep consumption low and driving enjoyment high in a big station wagon,” says Dr. Rolf Bulander, member of the board of management of Robert Bosch GmbH. There are similar advantages in other segments as well: while the responsiveness of modern gasoline powertrains makes them stand out in thoroughbred sports cars, the strong torque of the diesel powertrain is best for large SUVs.
Info chart: Bosch has put together a compact chart outlining the information drivers need to make the right choice. The advantages of the two powertrains are compared, and those who are uncertain can decide whether their individual driving profile is best suited to the diesel or gasoline variant. In addition, the info chart provides insights into the German car market, and shows the best-selling gasoline and diesel models.
