Equally beneficial to the aerodynamics are the small frontal area of 2.12 m² and the reduced rear track. Because this is 2 inches narrower than at the front, the rear wheels roll in the slipstream of the front wheels. The active rear diffuser, which automatically deploys at 37 mph, provides better airflow and thus contributes significantly to the reduced drag.

The technology vehicle gains further efficiency benefits from its tires, with their extremely low rolling- resistance rating of 4.7. Bridgestone developed these specifically for the VISION EQXX in partnership with Mercedes-Benz. By way of comparison, the current EU tire label requires a figure of 6.5 for the top rating in Class A.

A positive side effect of this electric braking is that the mechanical brakes are barely used. This makes it possible for the first time to use new types of aluminum brake discs that weigh significantly less than their steel counterparts.

The VISION EQXX gets an energy refresh around midday in the Po Valley near Milan – not at the charging station, but via its fixed solar roof. The 117 solar cells feed the 12-volt battery, which supplies power to auxiliary consumers such as the navigation system. The added value is measurable through the load this removes from the high-voltage battery, displayed by the onboard computer. Overall, the solar booster increases the range by more than two percent – which adds up to a good 25 kilometers (16 miles) on a journey of over 1,000 kilometers (621 miles).

(moteur) Its average efficiency in this application is 95%. That means 95% of the energy from the battery ends up at the wheels.

After 11 hours and 32 minutes of driving time, it ended its 1,008-kilometer (626 miles) road trip with a remaining range of around 140 kilometers (87 miles). 87 km/h de moyenne

 

A la louche , les autonomies EPA correspondent a une vitesse de 90km/h

Je crois que ça donne 570km pour une model 3 LR pour une batterie de 75 / 80 kWh

 

Donc a la louche , la EQXX consomme 50% de moins que cette model 3.

Belle performance !!!! 

 

Par contre , ils vont avoir du mal a appliquer les principes de ce prototype sur leur SUV/"tank" actuels.

@krucial celle là on la veut dans le Ioniq challenge 😅
