The car boasts a supercharged version of the next-generation Northstar V8 engine. The 4.2-L, all-aluminum V8 has a fully integrated supercharger/intercooler unit, for which GM has a patent pending, and comes with four-camshaft continuously variable valve timing plus a new low-friction valvetrain. The engine produces 302 kW (405 hp) at 6400 rpm and 522 N•m (385 lb•ft) of torque at 4000 rpm. The powerplant has been upgraded with a steel crankshaft, heavy-duty pistons and connecting rods, iron inserted main bearing bulkheads, and four-layer head gaskets.

Evoq also showcases a host of advanced technologies, either available now or currently under development. They include Night Vision; the Forewarn backup aid rear obstacle detection system; rear vision cameras, which replace outside rearview mirrors; a vertically anchored tire and wheel system from Michelin; and Communiport, a mobile multimedia information system with voice-activated navigation, electronic mail, and entertainment capabilities.
