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 13 - 13 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.

Official fuel consumption figures show that 13mpg is the best that can be reasonably expected in everyday driving, and after a year the SRT-10 will probably have shed at least £20,000 of its original list price. Consumables such as tyres and brake pads are expensive and will need replacing often while insurance on such a specialist car will be pricey.

With its powerful 8.3-litre V10 petrol engine, SRT-10 returns just 13mpg - so it's no surprise that it performs so badly on the eco front. It emits a whopping 489g/km CO2, which is very high – even for a quick sports roadster.

The SRT-10 needs servicing every 7500 miles, and the engine is unstressed for the most part so it should prove fairly reliable.
