Yahoo Autos Despite Its 6000 Pounds, 2024 Audi Q8 e-tron Handles Well on California Roads
Same model dimensionally as the original e-tron but gets major technical upgrades.
Bigger, more efficient battery brings range up to 300 miles.
Redone steering and suspension boost driving dynamics.
Should we consider the Audi e-tron’s six model years an apprenticeship? On sale this month is the Q8 e-tron, which effectively replaces the e-tron and will become the flagship electric model in the expanding Audi EV lineup.
It and its sister model, the Sportback e-tron, reside on the same wheelbase as the original e-tron and have virtually the same dimensions inside and out as its predecessor. However, the technical meat of this electric SUV is wholly new and substantially upgraded from the earlier model.
Audi brought journalists to Northern California to put the upgrades to the test on winding roads traversing the redwood forests, wind-swept coast, and vineyards that make this area a prime location for new model launches. The upgraded suspension and quicker steering ratio of the Q8 acquitted itself well along the twists and turns of the Russian River and up Highway 1.
While Audi executives talked about enhanced handling and agility, they also made the point that this car is at its core a luxury SUV with a standard air suspension, not a sports sedan. The line between Audi and its sibling brand Porsche is clear.
Bigger, Better Battery
The past six years have seen some substantial improvements in battery technology, which the Q8 showcases. The new battery is 23% bigger than the e-tron’s original one (it’s now 114 kWh). Thanks to advances in cell technology and chemistry, the car can charge faster, going from 10% to 80% in about a half hour on a 170- kW DC fast charger.
The Q8 features two onboard charging systems (running at 40 or 80 amps). On a Level 2 charger it takes 13 or 6.5 hours to fully charge the Audi, depending on which system you have.
The most important piece of information for the consumer will be a range that tops out at 285-300 miles. Different tires, driving habits, temperature, and other factors all can affect real-world range, but that now gives the Q8 competitive numbers against a growing field of luxury SUV EVs.
Audi dug into both the batteries themselves and the electric motors residing in the front and rear axles. The former got more efficient while still fitting into the same sub-floorboard location as the e-tron’s battery. With a better “stacking” construction, a new set of protection panels, and a more efficient battery management system, the bedrock of this EV has moved up considerably. The two electric motors also were completely redone. Additional windings generate a strong magnetic field leading to more efficiency.
While they were retooling the battery and electric motors, engineers also beefed up the suspension and steering. A quicker steering ratio compared to the original was augmented by stiffer front control-arm bushings and revised tuning of the chassis control system. With some additional aid by driver-assistance technologies such as lane-keep assist, the road handling of the Q8 was deceptive for an almost 6000-pound car.
In the end those more powerful batteries feed two asynchronous electric motors (front and rear) that put out 402 peak horsepower and will take you from 0-60 mph in 5.4 seconds. It’s not blindingly fast, but we found no trouble passing slower vehicles on the short straightaways or accelerating through traffic on the freeway. We didn’t have the chance to hit the 124-mph top speed but have no doubt about the motors’ ability to reach it.
