Fuel economy

Petrol engines 36.2 - 47.1 mpg
Diesel engines 53.3 - 57.6 mpg
  • M235i is priciest to run
  • 220d enjoys best mpg
  • But 218i is relatively frugal

For fuel economy, the diesel 220d has by far the best figures, at 53.3-57.6mpg and it also has the lowest CO2 emissions, at 110g/km. It is, however, considerably more expensive to buy in terms of purchase price than the petrol-engined 218i, so you’ll need to cover a high amount of mileage to see any gain from the fuel savings.

The 218i offers fuel economy rated at 42.2-47.1mpg from its turbocharged three-cylinder engine, which may be more cost-efficient on shorter trips around town than the diesel-engined 220d.

The Sport trim features 17-inch wheels as standard, which will help keep fuel costs down over the course of ownership. M Sport cars ride on 18-inch wheels, and even-larger 19-inch wheels can be added as an option – it’s worth avoiding these if you have an eye on CO2 output or fuel consumption.

Of course, the high-performance M235i xDrive is by far the thirstiest option, at 36.2-37.2mpg (provisional), and the heaviest cougher of CO2 at 153g/km. Apart from having a thirstier engine, it is also all-wheel-drive, which contributes to the fuel consumption.

During our time of testing, we saw an indicated 35-37mpg on a motorway cruise, but this dropped quickly to 32-34mpg during more spirited driving. As a result, the predicted range on a full tank varied from 377-384 miles depending on the selected drive mode.

The M235i and 220d models also come with a larger 50-litre fuel tank, while the 218i comes with a 42-litre one.

Reliability

  • First 2 Series Gran Coupe might be an all new model
  • But it’s still based on a 1 Series underneath
  • A three-year warranty should bring peace of mind

There shouldn’t be any major issues, but a three-year, unlimited-mile warranty is included just in case. Even though this is the first ever 2 Series Gran Coupe, it’s based on the 1 Series, and the previous generation of that displayed a solid result in customer satisfaction surveys despite a number of recalls.

Even though the 2 Series Gran Coupe isn't expected to be a huge seller, parts shouldn’t be difficult to source, should they need replacing.
