Renault creates a check EV to interrupt effectivity and vary data.
The Filante drove over 626 miles in below 10 hours, averaging a outstanding 8 miles/kWh.
Renault says it would use what it realized with this one-off to make its future manufacturing EVs extra environment friendly.

There’s nonetheless a variety of room for enchancment within the effectivity of electrical autos. Each new technology of EVs will get incrementally higher and goes a little bit bit additional on one cost, and the brand new Gen 3 EVs present clear enhancements. Renault created the Filante as a laboratory on wheels to see simply how far an EV may go along with right this moment’s expertise, utilizing a battery pack that’s an analogous dimension to what’s in a midsize electrical mannequin right this moment.

The result’s the streamlined Renault Filante demo automobile, which drove 626 miles (1,008 km) in below 10 hours, averaging a velocity of over 63 mph (102 km/h). When it accomplished its file run, it nonetheless had 11% left in its battery, which Renault says means it may have achieved the identical vary at an excellent greater velocity, 75 mph (120 km/h), or it may have gone even additional on the identical velocity, nearly reaching 680 miles (1,100 km).

The Filante recorded a median electrical energy consumption of simply 7.8 kWh/100 km, which is simply shy of 8 miles/kWh. That’s significantly higher than even essentially the most environment friendly of right this moment’s manufacturing EVs, just like the Mercedes-Benz CLA, Tesla Mannequin 3 or the Lucid Air, which may’t do a lot better than 5 miles/kWh even with their 800-volt structure.

The key is a mix of its low-drag design, low weight of simply 2,200 kilos (1,000 kg), and using very slim tires. That’s how the Filante can stretch its 87-kilowatt-hour battery pack so far as it has. Renault’s manufacturing Scenic E-Tech electrical crossover with the identical battery is rated at round 380 miles (610 km) on the WLTP check cycle, which drops by round 30% in the event you do sustained high-speed driving.

It additionally has power-saving steer-by-wire and brake-by-wire methods and the tires have been specifically designed by Michelin to reduce rolling resistance and do their half to decrease drag. Renault says that its objective with this examine was to search out methods to maximise EV vary, and it hopes to implement what it realized right here in its future manufacturing fashions.

It nonetheless has an extended option to go to even come close to what the Filante achieved (albeit round a closed check loop in sunny Morocco). Renault’s best present EV, the characterful and somewhat good 5 E-Techcan common round 4.3 miles/kWh in real-world driving. The smaller and lighter Twingo set to debut subsequent yr ought to do even higher.
