Mercedes EQXX sets electric car record by travelling 628 miles on one charge – and still had 192 miles of range left [Video]

German car giant Mercedes-Benz set out to diffuse concerns about electric vehicle range anxiety by taking its latest concept car on a massive single-charge trek across the Arabian Desert.

The Vision EQXX has been driven from Riyadh to Dubai on a single battery charge earlier this month, covering a massive 627.6 miles in almost 15 hours without having to stop.

The aerodynamic car set a new efficiency record by travelling 8.4 miles per kilowatt hour (kWh) and completed the trip in baking hot conditions with 192 miles of range remaining.

While the EQXX is only a prototype model for now, Mercedes bosses have promised that its tech will be filtered down into its production EVs before the end of the decade.
