MOST city cars are pretty small inside and have trouble carrying four adults in reasonable comfort.

But there is one out there that comes with five doors as standard and it can get that four people quart into a pint pot.

The Suzuki Celerio replaced both the Alto and the Splash when it was launched in 2015, and it's very cheap to run in every way, with one model even having no road tax.

There are just two engine choices - both 1.0-litre three cylinder petrols producing 67bhp, and driving the front wheels through a slick changing five speed gearbox with a very light clutch.

They're smooth and reasonably quiet unless pressed, but become a little raucous towards the top end because at this level, soundproofing is not a major concern.

Because of the car's light weight, performance is quite acceptable from such small engines, with the zero to 60 miles an hour sprint taking 13.1 seconds in both.

And they can easily keep up with the flow of traffic on the motorway - I‘ve done trips of over 200 miles in one without any feeling that it was out of its depth.

Of course, such small cars are not about performance - they're about economy and low, low emissions, and this is where the Suzuki really scores.

This is the most economical small petrol car on the market that I've been able to find .

The two versions of the engine are only separated by economy and emissions.

The standard unit is capable of an excellent 66mpg with emissions of 99 grammes per kilometre, but the super economy Dualjet version ups the ante to a superb 78.4mpg and just 84g/km, meaning that there's no road tax to pay.

The Celerio has similar performance to the best of the rest, and is ahead of most other city cars. But it beats them all on economy and emissions.

The manual five speed gearbox is very easy to use, but there is also an automated manual with a fully automatic option that can be driven by those who have an auto-only licence, and it's just as economical as the manual.

The roadholding is good enough to be engaging and fun, and there is reasonable feel from the steering, helping towards well-balanced handling.

Where it scores highly over most city cars is the quality of the ride. It takes potholed and much repaired town and city roads in its stride at low speeds, and can even smooth out a rough country road taken much faster.

Low prices new mean it's a model that's great value secondhand and like all Suzukis, it has a good reputation for reliability.

All have five full seatbelts, but three adults in the back would be a squeeze. There's good space for four as I've said, with enough head and leg room in the rear for one six footer like me to sit behind another.

Add to that a boot that is the largest in the class at 254 litres, and you end up with a very practical small car package.

At such reasonable prices, it comes with plenty of equipment straight out of the box, and there are four trims to choose from - City, SZ2, SZ3 and SZ4.

Even SZ2 gets a height adjustable driver's seat and folding rear seat, traction control, front electric windows and central locking.

The SZ3 adds air con and alloys, while the top SZ4 has electric mirrors, rear electric windows and front foglights.

Pay about £6,140 for a '19 19-reg SZ2, or £7,850 for a '20 69-reg SZ3 Dualjet.
