Toyota Prius MPG & CO2 emissions

The Toyota Prius delivers amazing efficiency for a conventional hybrid car, so it should be very cheap to run

MPG (comb) MPG (high) MPG (extra high) CO2
60-68mpg - - 75-85g/km

Strong fuel economy puts the Prius at the top of its class, which means you can run it on a relative shoestring. The car intelligently uses the hybrid setup itself to maximise the efficiency on offer.

Toyota Prius MPG & CO2 emissions

With claimed fuel economy of up to 68mpg combined and CO2 emissions as low as 78g/km, the Prius is an incredibly efficient vehicle. Of course, these are official claims so take them with a pinch of salt, but compared with its closest rival, the Hyundai Ioniq, it’s more efficient.

These figures are for the lower trim level Prius models, which come on 15-inch wheels. These mean the economy should be strong, while the smaller rims also improve the ride quality.

If you go for a higher-spec trim level (Business Edition Plus and above) these stats aren’t quite as good. However, this importantly doesn’t affect the group the Prius falls into for company-car tax (19% Benefit-in-Kind) so you don’t pay a financial penalty if you’re a business user, while road tax remains the same, too.

It’s a similar story for the Ioniq, though – the higher-spec trim level on 17-inch wheels claims 70.6mpg and 85g/km CO2. Although both Ioniqs fall into the same BiK company-car tax bracket as the Prius, so running costs will be similar.

Our sister title Auto Express has extensively tested the Prius and found that you can expect around 58mpg, which was roughly 10mpg more than the Hyundai, so the Prius exerts its authority when it comes to economy – let’s face it, this is what hybrid cars are about.

With a 43-litre fuel tank, based on these real-world figures you should expect a cruising range of around 550 miles. Given the Ioniq has a larger 45-litre tank, this is a fair bit more than the Hyundai’s predicted 474-mile range.
