Every 2007 Mazda CX-7 model, from the base front-wheel-drive Sport to the all-wheel-drive Grand Touring, gets the same engine, a turbocharged 2.3-liter, dual overhead cam four-cylinder with direct injection that’s good for 244 horsepower at 5,000 rpm and 258 lb.-ft. of torque. The Hitachi Warner turbo maxes out at 14.9 psi, and the exhaust runs straight back to dual chrome tips to lessen back pressure. A six-speed automatic transmission with a manual mode directs power to a front- or all-wheel-drive system and, subsequently, standard 18-inch alloy wheels wrapped in 235/60 Goodyear Eagle RS-A tires.
