The 2017 model year marked a couple of firsts for the Audi Q7. The most important of which was probably the introduction of the e-tron badge. The e-tron model takes the 3.0-liter TDI and a 94 kW electric motor to churn out 373 horsepower and 516 pound-feet of torque. The first hybridized diesel from Audi is also the most powerful engine available. On the other side of the spectrum, however, is this new 2.0-liter, gasoline-drinking, four-banger. As the first four—cylinder to be offered in the Q7, it can’t be compared to the power offering from the outgoing model, but Audi Claims it is 22-percent more fuel efficient that the 2015 model with the 3.0T V-6.
