Audi has completely updated the Q4 e-tron crossover for the 2024 model year, adding a newly tuned suspension, increased efficiency, and more standard equipment. The changes result in higher efficiency and thus more range for the luxury compact SUV.
The Q4 e-tron uses a 77 kWh battery (usable, 82 kWh gross). Audi has optimized cell chemistry to improve both DC fast charging capability (28 minutes to get from 10 to 80 percent). Rear-wheel drive models have 135 kW of charging capability and Quattro (AWD) models have 175 kW. Fast charging can charge to 80 percent, after which slower charging commences in order to preserve battery life.
Driver assistance system have also seen improvement in the new Q4 e-tron. Optional Adaptive Cruise Assist can now aid in lane changes.
The drive system’s new efficiency comes from an newly-optimized permanently excited synchronous machine (PSM) on the rear axle. This new drive setup has higher efficiency and more power output. IT’s the only drive unit on the rear-wheel driven Q4 and the main drive unit for the all-wheel drive Quattro models. Range for the Q4 Sportback 45 e-tron model, for example, expands to 349 miles per charge (WLTP cycle). Power production raises to 286 PS (210 kW) and acceleration improves slightly to 6.6 seconds for 0-100 km/h (62 mph). Or to 5.4 seconds for top-line models (Sportback 55 e-tron Quattro). Top speed for all models is held at 112 mph.
The PSM system uses optimized thermal management and an energy-saving cooling design. Gear wheels in the transmission are specially shaped to help distribute the cooling and lubricating oil, keeping temperatures low. The oil is then circulated through a cooling loop while a water-cooled jacket around the stator minimizes motor heat.
The 2024 Audi Q4 e-tron models will enter showrooms soon, with pre-orders opening this week. Pricing starts at €52,950. Audi has not announced North American availability as of publication.
