Currently reading: How city cars can be reborn for the EV era

We need cheaper EVs created by rival makers pooling resources - and fast, says one industry boss. We create one

The trend towards bigger, heavier cars with more safety kit and features has put the future of the affordable city car in serious doubt.

Small cars used to be a popular sight in our cities, but they’re now an endangered species – which is bad news for anyone seeking an affordable new car.

A few months ago, Renault Group CEO Luca de Meo proposed a solution: taking inspiration from Japan’s small urban vehicles, known as kei cars, believing that a European version could help make for affordable mobility and help get older, smoggier cars off European roads.

De Meo has a bullish view on cross-manufacturer co-operation (inspired “by Airbus”) for electric European kei cars. “Compact cars could create a growth surplus for Europe” of £500 million in annual GDP and create 10,000 jobs, he said.

De Meo had spoken to Volkswagen about a possible joint venture to produce a cheap small electric car before talks broke down. However, a sub-£17k Renault Twingo remains on course for a 2025 reveal and VW hopes its similarly conceived ‘ID 1’ can make production in 2027.

The Renault Group boss sees the future as “going back to the fundamentals of the industry, mass development of small cars for urban travel and last-mile deliveries, adding benefits such as reserved parking spaces, cheaper parking and reserved charging points”.

With electric car sales currently sagging, de Meo’s plan seems to be two-pronged: not just reducing the price, but also giving up on trying to match the range achieved by combustion-engined cars, because range equals cost. De Meo thinks his vision of the future can appeal to “middle-class buyers” who cover lower daily mileage and have completely vacated the new car segment as new models have become steadily more expensive.

What Autocar's vision of a kei car for Europe would be like

Electric range

Engineering co-operation across rival car makers has a chequered past, but getting production volumes as high as possible is crucial to reducing the cost of a city EV. Range would need to be 110 miles in the summer, well in excess of the average daily use of 30 miles.

Platform

Creating a new platform from scratch is an expensive business. The Twingo is set to use a development of the new AMPR Small (formerly CMF-BEV) architecture, with a further reduction in costs of 40%, partly realised by reducing the number of parts and cutting software costs by working with Google. 

Bodystyles

Renault has turned to an unnamed Chinese firm to advise on engineering and producing the Twingo and its platform as profitably as possible. Ultimately, the more brand collaboration the better. The platform’s operating system software would be simplified but a wide range of bodystyles would be key – including a longer wheelbase for a small delivery vehicles and five-door versions for the school run.

Back to top

Environmental impact

The environmental impact of a small car is 75% lower from cradle to grave than the bigger models more commonly bought today, according to de Meo. He says measures including social leasing, free parking spaces, preferential charging prices, lower interest rates on loans and incentives for young buyers could help cut costs and drive user or even ownership demand.

Materials 

Reducing the amount of lithium used is a priority. De Meo claims that the cost of lithium in a typical EV battery alone is equivalent to the factory price of a combustion engine. The new sodium ion packs contain no lithium, nickel, cobalt or graphite, according to Swedish developer Northvolt. 

Battery chemistry

What type of battery chemistry? Lithium iron phosphate (LFP) seems to be the front runner for the Twingo, though another cheaper alternative, sodium ion, is being pushed by Chinese giant BYD. Weight is an issue with the new chemistries, with any city EV needing to be under 1100kg.

No they're really not.

Batteries are getting bigger, and (with LiFePo), heavier per kWh.

Density has gone *backwards* with LiFePo - batteries that were initially used for home systems (heavier but cheaper and safer).

I love cars, have three children and live in central London, so feel perpetually conflicted.  The concept of a 'city car' is an oxymoron, at least in a city where there is workable public transport and roads that accommodate cyclists.  To aim to create a class of car that has range that limits it to urban use and is so cheap that it encourages huge sales at a time when many cities are already congested with traffic makes no sense.

De Meo's vision of the future is instructive: “going back to the fundamentals of the industry, mass development of small cars for urban travel..."  His comment suggests he thinks that a wave of new city car sales is what is best for the car industry, not for cities and those living there.

Having lived in Japan, I think it is instructive that the country that created the kei car has some of the best public transport systems (and most congested cities) in the world.

Car companies should certainly aim to create efficient, small cars but it would be a mistake to target urban use only.  Like the Citroen 2CV and e-C3, an affordable small car should accommodate at least four adults, have a reasonable boot and range of at least 150 miles: there is absolutely no reason why small cars should not be used for long journeys.

Car companies obviously have a serious problem with 'middle-class buyers' leaving the new car market but this is more of a problem for the companies than said buyers.  Most of us are happy to look to the very well stocked second hand market for affordable and eco-friendly cars (2023 UK used car sales 7.2m; new car sales 1.9m (private buyers <40% of that)).  If De Meo wants to align the interests of Renault and the current urban 'middle-class buyer', perhaps he should be looking for more radical solutions such as how to re-engine existing cars with electric powertrains.

The problem is, battery technology is improving so rapidly that a 110 mile car will rapidly become obsolete and have no resale value.

Go on then tell us what a Electric City cars range needs to be.

With the massive caveat that this is subjective opinion... I think most people spending thousands on a car would expect it to be capable of travel between cities (even if they rarely do this). I.e. capable of driving for 2-3 hours at highway speed (at which point safety recommendations dictate taking a break).
