Mercedes Vision EQXX electric car completes 626-mile journey on a single charge


Mercedes-Benz has proved that electric cars of the future should be able to cover significant distances on a single charge by driving its latest concept vehicle 626 miles across Europe without needing to plug it in.

The German manufacturer took its svelte Vision EQXX from Stuttgart to the picturesque Côte d’Azur via the Swiss Alps and Northern Italy in just 12 hours – and upon arrival it still had 15 per cent battery range remaining.

Bosses said the surplus charge would have provided enough power to cover an additional 87 miles, suggesting the car is capable of 713 miles on a brimmed battery pack. 

That’s some 308 miles further than the longest-range Tesla can travel on a single charge and enough for the average Briton to drive for five weeks without needing to find a charging point.

Charging on: Mercedes has completed a 626-mile non-stop journey across Europe in its concept electric vehicle without having to pull over at a charging point 

Departing from the German city of Sindelfingen at 7am, the Mercedes rolled into Cassis in the South of France at 7:02pm without once having to pull over to finding a charging device. The flap over the charging socket was even sealed for the duration.

The average speed on the journey was 54mph, with the trip including stop-start city traffic as well as 87mph blasts on the German Autobahn, with average electricity consumption of 8.7kWh per 100km.

The successful voyage means the EQXX has already delivered on a promise made by the luxury car brand during its unveiling earlier this year.

Mercedes said at its debut at the Consumer Electronics Show in Las Vegas in January that the zero-emission concept would be able to cover over 1,000km (621 miles) on a fully-charged battery.

The recent achievement means the Mercedes has easily bettered the 405 miles of range offered by a single-charge Tesla – the range dual-motor, all-wheel-drive Model S – and gazumps everything else on the market to date.

Currently, the electric vehicle with the longest range sold in Britain is Mercedes’ £100,000 EQS luxury saloon, which can go for 465 miles before the owner needs to plug it in, while the Lucid Air’s 510-mile range is the longest officially registered by US regulators.

Still, the pair are 248 and 203 miles shy of the EQXX’s 713-mile range respectively.

With range being one of the biggest sticking points preventing consumers from making the switch to EVs, the EQXX suggests this could soon become a thing of the past for drivers in the UK. 

A recent study found that the average Briton was driving 6,800 miles a year pre-pandemic (based 2019 figures). That works out at 142 miles a week.

If Mercedes was to bring the zero-emission car to market now, an average motorist would only need to charge it once every five weeks – or 11 times per annum.

‘The Vision EQXX is the most efficient Mercedes ever built,’ said Ola Källenius, chairman of the board at Mercedes-Benz Group AG. 

‘The technology programme behind it marks a milestone in the development of electric vehicles.  

‘It underpins our strategic aim to ‘Lead in Electric’,’ he added.

Mercedes EQXX’s 626-mile journey on a single charge by numbers

Journey start: Sindelfingen, Germany, 5 April 2022, 7:00am

Journey end: Cassis, France, 5 April 2022, 7:02pm

Travel route: Sindelfingen, Gotthard Tunnel, Milan, Cannes, Cassis 

Driving distance: 1,008 kilometres (626 miles) 

Total travel time: 12 hours and 2 minutes

Total driving time: 11 hours and 32 minutes 

Average speed: 87.4 km/h (54.3mph)

Maximum speed on motorway: 140 km/h (87mph)

Average consumption: 8.7 kWh per 100km 

Battery charge level on arrival: 15% remaining range, approx 140km (87 miles) 

The EQXX’s range – which is more than double that of most electric models on sale at the moment – isn’t achieved using a larger battery pack. 

In fact, it uses a 100kWh battery, which is smaller than the unit fitted to some of its most expensive existing models.

However, the concept vehicle’s battery pack is 50 per cent smaller and 30 per cent lighter than what’s on the market at the moment, which means it can be used in more compact cars if necessary.

It has been developed with the help of the Mercedes-AMG Petronas F1 Team, with the brains behind Lewis Hamilton’s recent Formula One success providing their expertise to develop the EQXX’s electric drive system.

Also boosting available energy are the 117 solar cells on the Mercedes’ roof that feed into a 12-volt battery to power non-drivetrain electronics, such as the infotainment screen and interior lighting.

This saves the main battery’s capacity exclusively for driving, with bosses claiming the solar panels add around 16 miles of range on a 621-mile trip.

As well as a lighter battery, the EQXX has a featherweight construction, which results in a total unladen weight of just 1,755kgs – that’s barely much more than a Ford Focus family hatchback. 

It’s bullet-like profile means it’s also super efficient at cutting through the air and specially-developed low-rolling-resistance Bridgestone tyres also reduces demand on the drivetrain and improves range.

The concept vehicle's battery pack is 50% smaller and 30% lighter than lithium-ion packs currently being used by EV makers, which means it can be used in smaller cars if necessary

Markus Schäfer, Chief Technology Officer at Mercedes-Benz, said the concept will now provide a ‘blueprint for the future of automotive engineering’. 

He added: ‘Many of the innovative developments are already being integrated into production, some of them in the next generation of modular architecture for compact and midsize Mercedes‑Benz vehicles. 

‘And the journey continues. With the Vision EQXX, we will keep testing the limits of what’s possible.’

While only a concept for now, tech used in the EQXX is likely to debut on Mercedes’ forthcoming MMA platform, which will underpin all its new electric models introduced from 2024.

The battery, inverter and e-motor – which is claimed to be 44 per cent more efficient than current electric motors  – will likely be carried over from the prototype car into series production models in the coming years.
