Bosch info chart provides guidance on selection of gasoline or diesel

Bosch has produced a compact chart outlining the information drivers need to choose between gasoline or diesel powertrains. 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.

A diesel-powered car consumes up to 25% 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, Bosch said.

Both powertrains have their strengths, Bosch noted. 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,” said 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.

In addition, the info chart provides insights into the German car market, and shows the best-selling gasoline and diesel models.




It's not much of a guide.

You have 3 variables, and a threshold for only one of them.
Two of the variables (size and trip length) are a bit hazy - people are unlikely to know the exact answer.

There is no way of unifying the 3 variables.

What they need is a little app or website where you type in the annual mileage, the weight of the vehicle and your typical journey length and style, then give a recommendation (say on a scale of 1-3 or 1-5.
1=Certainly diesel, 3(or 5) = certainly petrol, middle range - doesn't matter much.

They might also mention how many years you intend to keep the vehicle - if you plan to keep it for 10 years, a diesel might be a better bet.

(In Ireland there is a rule of thumb: < 1.3L = petrol.
> 1.6 = diesel - 1.3 - 1.6 - whatever.


How about warm-up time? People buying a pack of cigarettes down the block would appreciate gasoline.
