The Mercedes-Benz GLC and the Audi Q7 have one obvious incongruence between them. The Q7 has a seating capacity of 7, while the GLC only seats 5. If you need the extra two seats, the debate ends there. If you don't need to haul 6 children with you everywhere you go, you may be interested to know that the 2017 Mercedes-Benz AMG® GLC 43 SUV costs roughly the same amount as the Q7 and features many more opportunities for performance and luxury.
To make room for the extra two seats in the Q7, the Audi is longer by more than a foot. The wheelbase, however, is only a couple inches longer, meaning the extra length on the Q7 exists outside of the wheelbase, sacrificing stability and handling capabilities. The extra length also means more weight, which means acceleration lag and lower economy numbers.
Under the hood, the Mercedes-Benz has the same size engine as the Q7, but they use different forms of forced induction to make extra power. The Mercedes-Benz AMG® uses Mercedes-Benz biturbo to make more power and torque than the supercharged Audi Q7. Thanks to the surplus of weight that comes with the Q7, the GLC is also more efficient by a long shot. In the end, it comes down to what you need the SUV for. If you need something that is big enough for a family of 7, the Q7 is your only choice. If you don't need the extra room, you are much better off investing your money in a Mercedes-Benz AMG® with a hand-built engine. If you have any questions about why the GLC is one of the best SUVs in the industry right now, come to Mercedes-Benz of Arrowhead for a test drive!
