Fuel economy

Petrol engines 23.9 mpg

This car costs £59,995 in the UK, so even before you’ve paid for any fuel or VED car tax rates it looks like Lexus RC F running costs will be on the prohibitive side. Certainly, any car that pumps out 252g/km of CO2 (meaning a correspondingly high annual VED rate) and only returns 26.2mpg on the official combined cycle isn’t going to be the cheapest to run.

Especially when in our limited experience of the vehicle that economy figure was far closer to 16mpg than 26mpg when driving the car as its Japanese engineers intended.

Large 19-inch tyres, huge six- and four-piston brake callipers requiring gigantic brake pads and 380mm or 345mm (the latter on the rear) brake discs mean consumables aren’t going to be cheap either.

You don’t choose one of these cars to be kind to the environment as Lexus RC F emissions are provided by one engine and one engine only – a 5-litre naturally aspirated V8 petrol. That means, in terms of headline figures, this super-coupe pumps out 252g/km of CO2.

To be fair to the Japanese firm it has attempted to lessen the blow to both the environment (and your wallet) by developing the engine to run on the more fuel-efficient Atkinson cycle at constant throttle and cruising speeds. It will revert to the more traditional Otto cycle when being driven hard though, providing optimum torque and power when required.

But when the turbocharged BMW M4 achieves 194g/km, and the forthcoming Mercedes C63 AMG may even better that, the Lexus does rather fall behind in comparison.

As firm whose reputation is built on customer service and dependability of its cars, it’s no surprise that Lexus RC F reliability is tipped to be exemplary. The engine comes form the IS F, though it has been suitably upgraded and re-worked for better response, more power and increased efficiency – and it’s likely to be as reliable if not more so than it was in that application.

And every Lexus is screwed together with the sort of solidity and precision that would shame a bank vault, so there’s no worry about errant pieces of loose trim or worn materials – a ten-year, 100,000-mile old example should look almost as good as the day it left the factory.
