Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 23 - 52 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Depreciation is the biggest burden, but it’s unlikely to be as bad as Alfa Romeos have previously been. This is due to restricted supply (just 700 are expected to be sold each year) and lower discounts on new cars from dealers. Fuel economy, insurance, road tax and servicing costs are in line with rivals.

The Spider scores fairly badly on the eco front. With an average of 241g/km CO2 across the model line-up, its emissions are quite high for a sports convertible thanks mainly to the all-wheel drive V6 model. Equally the range is not very frugal, averaging 30mpg. However there is the option of a diesel, with a far better 179g/km CO2 output and 41.5mpg fuel consumption.

Owners of the previous generation Spider are surprisingly complimentary about the car’s reliability, which goes against Alfa Romeo’s reputation for poor build quality – see our owners’ review section for details. However, dealers aren’t held in such high regard, so it may be worth searching for a decent independent for servicing. The latest car is all-new, plus Alfa Romeo’s build standards have improved considerably in recent years, which bodes well for the future.
