Audi has announced that the 2018 Audi Q5 now has the highest mpg in its segment. With a 25-mpg city/highway combined fuel economy rating, the 2018 Q5 achieves a +3 mpg improvement over the 2017 Q5.
Audi says that it was able to improve the Q5’s fuel economy thanks to a new generation of quattro all-wheel drive with ultra technology. Quattro with ultra technology utilizes an electronically controlled multi-plate clutch along with a decoupling rear axle differential to achieve fully variable torque distribution. Unlike other all-wheel drive systems that can take up to two seconds to fully engage, quattro with ultra technology can be fully engaged in under 250 milliseconds.
A series of pins, levers and springs engage and disengage a unique front-multi plate clutch, to divide torque between the front and rear as needed, while a rear dog leg clutch connects and disconnects the prop shaft and rear differential to improve efficiency.
The 2018 Q5 is powered by a new 2.0L four-cylinder engine that’s mated to a seven-speed S tronic dual-clutch automatic transmission, to produce 252 hp and 273 lb-ft of torque. The Q5 can zoom from 0-60 mph in 5.9 seconds, 1.1 seconds faster than its predecessor.
