Stellantis CEO claims quicker EV acceleration is a safety feature

Stellantis final week detailed its STLA Large platform, which the automaker claims can home powertrains able to hurling an EV from 0-60 mph in 2.0 seconds.

That breathtaking acceleration determine could also be one thing Stellantis CEO Carlos Tavares now claims is a security function.

That is as a result of fast acceleration permits for faster overtaking, Tavares told Top Gear and different media, utilizing the necessity to overtake a slow-moving truck on a two-lane street for example.

“The extra acceleration you will have, the safer the situations underneath which you overtake might be,” Tavares stated, “and from that perspective the BEV know-how is nice as everyone knows.” The thought appears to be {that a} 2.0-second acceleration time is inherently safer than the still-quick acceleration occasions of different EVs.

In Stellantis’ case, nevertheless, efficiency will probably come at the price of effectivity. The automaker has described the STLA Giant platform as supporting 500 miles of vary from 118-kwh battery packs in environment friendly sedans, or 2.0-second acceleration in efficiency vehicles like the Dodge electric muscle car tipped to make use of the platform. It is an both/or proposition.

Typically, the faster you make an EV, the extra rigorous its battery cooling and bigger different elements should be—so that you lose effectivity. Porsche engineers told Green Car Reports at one level that had they engineered the 800-volt Taycan for vary above efficiency, they may have achieved a a lot larger vary.

The Kia EV6 GT, for example, is simply rated at 206 miles, whereas in different slower-accelerating variations it is rated as much as 310 miles. And the Lucid Air Sapphire cannot match the Air Grand Touring mannequin’s 516 miles of vary, regardless of related battery capability.

As for Tavares’ declare that acceleration boosts security, what he is arguing could also be a fringe case and really depending on driver restraint.Because the Insurance coverage Institute for Freeway Security (IIHS) argued in 2021, even slight increases in the speed of crashes can have dire penalties on human final result. Within the phrases of physics, acceleration might enable dodging some crashes, nevertheless it makes the terminal velocity a lot larger for others. It additionally amplifies the considerations in regards to the dangers of heavy EVs to different motorists.

It is necessary to notice that in a 2020 analysis, the associated Freeway Loss Information Institute (HLDI) discovered that the crash price and financial losses for EV was truly decrease versus typical automobiles—a head-scratching distinction versus what insurers and a few corporations together with Hertz have continued to argue. Though a few of these EVs may need larger horsepower and stronger acceleration, at the least early on real-world outcomes did not go together with the HLDI’s personal longtime steerage that, for youthful drivers particularly, sports activities vehicles and higher-horsepower automobiles, together with smaller automobiles, had larger crash charges.

Briefly, keep tuned for extra knowledge. Particularly as extra non-Tesla EVs hit the street in bigger numbers, we’ll see if higher-power, quicker-accelerating EVs are in quick safer, or whether or not they appeal to a number of the identical risk-prone drivers as these sports activities vehicles did prior to now.
