BEV vs. ICE at Streets
This graph provides a lesson about the importance of tire grip. Despite the huge advantage exiting corners that all-wheeldrive traction should give the I-pace and Model 3, the Alfa is repeatedly faster on the straightaways with its mere rear-wheel drive. That’s despite a 0–60 time that’s 0.5 second slower than the Tesla’s.
When it comes to lapping, the three most important things are tires, tires, and, oh yes, tires. The Alfa’s grip makes it the lateral-g champ in every corner. But its real dividends appear later in corner exit, where the AWD cars display periodic understeer, forcing Randy to briefly back off. A notable Tesla gain, though, appears in how much speed it’s holding heading into Turn 10 (a gambit Randy overplayed in a later lapping session, going off in Turn 11 due to both this speed and a miscue with its brakes).
Two tidbits about the Tesla’s lapping: Even while it’s clocking a lap time that beats the Mustang GT PP2’S, its energy use was an astonishing 17 mpg-e (electricity use if it were an equivalent number of gallons of gas). And its brakes are slightly less stressed by Track mode’s stronger regenerative setting, taking up the slack.
ALPHA ROMEO The Alfa Romeo Giulia and its internal combustion V-6 hold on to the top spot—for now—but the BEV betas and gammas are closing in.
