Engine 1.0 MPI GreenTech
Official average 68.9mpg*
CO2 output 96g/km

Despite its advancing years, the Skoda Citigo still feels as fresh as ever. It's refined and comfortable to drive, its interior is practical and solidly built, plus it's safe, having earned five stars during Euro NCAP crash testing. As an added bonus, two engines are available within our parameters, the most economical of which – a 59bhp 1.0-litre – is referenced above. The other is a 74bhp 1.0-litre that can average 67.3mpg and emit 98g/km of CO2; these extremely minor trade-offs are worth the extra poke. Either way, it's our used go-to for affordable, economical petrol cars. The only reason its mechanical siblings, the Volkswagen Up and Seat Mii, don't also feature on this list is due to their scarcity within our parameters.

Speaking of exceptional value, the Suzuki Celerio is a real bargain to buy and run, yet can still hold its head high in the face of competition. Its 68bhp 1.0-litre engine provides around the same grunt and fuel efficiency as we've seen from other cars on this list, and the Celerio is reasonably polished to drive as well. Practicality is another strong suit for this five-door-only city car, because its interior is surprisingly spacious and so is its boot. Insurance and servicing costs will be low, plus Suzuki has a really good reputation for reliability.

In 2009, we named the Ford Fiesta our What Car? Car of the Year, and in 2013 it only got better. It received a facelift, along with a new engine in the 1.0-litre Ecoboost unit. This three-cylinder turbo is available in three states of tune: 99bhp, 123bhp and 138bhp. As an engine ahead of its time, it gave the Fiesta a blend of performance and economy that would exceed expectations, and they still impress to this day. It's the best-handling car in its class and exceptional value for money. The only reason this five-star car is beaten by four-star ones is because our budget only buys you an older, higher-mileage example.

For a more practical city car, when compared to our previous three, consider the excellent Kia Picanto. It, too, is available in three-door and five-door forms, although it has a roomier interior and bigger boot. Its 68bhp 1.0-litre engine – not to be confused with the unit in the C1, 108, 208 and Aygo – provides decent performance and great economy, making it fantastic in town. Confidence-inspiring reliability acts as the cherry on top of this well-rounded package.

The Aygo ranks higher still, with Toyota's reliability rating of 97% being the main factor in that. It's also the most distinctively styled out of the city car trio, helping it to stand out from the crowd. Plenty of trims are available – seven, to be exact – and used examples are common, meaning there's plenty of choice. One decision you don't have to make is what engine to get, however. There's only one available within budget, and it's the fuel-sipping 68bhp 1.0-litre.

If the 108 and C1 are so similar, why does the latter rank higher? Well, while the margin isn't substantial, the C1 earns some bonus points for generally having more examples available on the used market, as well as Citroën (as a brand) proving more dependable, as seen in our latest What Car? Reliability Survey. Its reliability rating of 95.6% significantly trumps Peugeot's less impressive 89.6%. Apart from that, both cars share the same praises.

Built as part of a joint venture that resulted in it sharing common parts with the Citroën C1 and Toyota Aygo, the Peugeot 108 is extremely frugal with the 68bhp 1.0-litre engine under the bonnet – a unit available in all three cars, as well as the 208 previously listed. Available in three and five-door forms, the 108 ticks many boxes, including good equipment levels, nippy performance (better than that of the 1.0-litre 208 due to less weight) and the option of a fabric roof for those who worship the sun. All of this can be had for very reasonable money.

While your usual city car has a front-engined, front-wheel drive layout, this generation of the Renault Twingo features the opposite. The idea is that, with its engine in the rear, this frees up space for a bigger interior without compromising crash safety. It works, too, because four adults can fit very comfortably inside what is a compact package. Does the layout negatively impact fuel economy? No: its 69bhp 1.0-litre engine holds up against rivals, and so does the 89bhp 0.9-litre unit with its average of 65.7mpg.

With an iconic name and retro looks, the Fiat 500's 21st century revival has proved very successful. Another factor aiding that success is its range of economical engines, with the best of the bunch being an 85bhp 0.9-litre unit. Despite having the most power of any city car on this list, the 500 has the highest fuel economy figure, too. It would rank higher if it weren't for its age and shortage of space.

A small car with the fuel economy typical of cars even smaller, the Peugeot 208 is at its most fuel efficient when paired with the entry-level engine: a 68bhp 1.0-litre unit. With the parameters we've set, it's close to being the only member of its class to qualify, meaning it's one of the most spacious cars we have to recommend. It's incredibly affordable to buy and run, although questionable reliability is worth mentioning.
