Mercedes-Benz shows EQC summer testing

The all-electric crossover was taken to the Iberian peninsula to experience temperatures of up to 122 degrees Fahrenheit.

Mercedes-Benz has released another gallery of EQC photos as pre-production prototypes complete summer testing.

After successfully finishing winter trials, the all-electric crossover was taken to Spain to experience temperatures of up to 122 degrees Fahrenheit on the Iberian peninsula.

"With the finishing straight in sight, we are now able to absolve another extremely demanding test programme with our pre-series vehicles," says EQC chief engineer Michael Kelz. "But after successfully completed endurance tests in winter at minus 35 degrees C, we are confident that the heat trials will confirm that we are well on schedule for the start of series production."

Engineers validated the EQC's battery cooling system, hot-weather range and air-conditioning system ahead of production.

The crossover is expected to arrive in showrooms by 2020, reportedly with a $100,000 price tag.
