Toyota Aygo review - MPG, CO2 and Running Costs

Frugal, clean and warrantied to the hilt. Living within your means can be fun after all…

Although the 1.0 VVT-i is fundamentally the same unit as used by the Toyota Aygo’s predecessor, it’s been re-engineered for the new model. A higher compression ratio of 11.5:1, a new low-friction timing chain and a cylinder head with built-in exhaust manifold to save weight have all helped to improve fuel efficiency and cut emissions.

The mods allow Toyota to boast of raising the engine’s thermal efficiency (the amount of the fuel’s energy it converts to power) to a class-leading 37 per cent. That’s impressive, but it’s a cautionary thought that even in an economy-minded city car like this you’re losing 63 per cent of the energy in your petrol tank to (mainly) waste heat and friction. And that’s in those rare moments when the engine is running at peak efficiency.

Still, the numbers aren’t too bad. Fuel economy and emissions are rated at 53.3mpg and 93g/km of CO2 in the five-speed manual model, while the x-shift auto returns 51.4mpg and 95g/km. 

Sadly, the Aygo no longer qualifies for free ‘road tax’, with all models falling into the fifth tier of the new rates, which equates to £120 in the first year, followed by the £140 standard rate.  On the plus side, Toyota’s attractive finance plans will get you behind the wheel for around £130 a month.

Also look out for regular price drops on the entry-level models, with a few hundred pounds often removed from the advertised price.

Insurance groups

Perhaps the implied ‘youth’ appeal of its zingy styling makes a difference, but it’s more likely to be design details like those relatively expensive projector headlamps that mean the Toyota Aygo will cost you more to insure than some of its more staid-looking city car rivals.

The entry-level Aygo x is rated in insurance group six, and the rest of the range falls into group seven.

By way of contrast the entry-level Hyundai i10 starts the bidding off with an impossible-to-beat insurance group one, while the Skoda Citigo, VW up! And SEAT Mii all undercut the Toyota’s group ratings too.


With Toyota expecting to sell a quarter of all European Aygos here in the UK, there isn’t likely to be a shortage of used models on the market.

In fact, there’s been a bit of downward pressure on city car values as a whole, as availability of used models increases. That said, because new prices are relatively low, any percentage shifts may not look too painful when converted to cold hard cash.

Still, some industry predictions have the Toyota Aygo faring worse than cars leaving the same Czech factory wearing Citroen or Peugeot badges. So you may well be looking at an average drop in value after three years of close to 70 per cent for the entry-level Aygo, with the Peugeot sneaking-in under 60 per cent, and the Citroen splitting the difference.
