Under the hood, a 2.5-liter, turbocharged, five-cylinder 227-horsepower engine delivers power to the front wheels through a six-speed manual or an optional five-speed automatic.
Kelley Blue Book would like to see more boost from the turbocharged five-cyllinder, arguing that "a little more horsepower would turn the C70 from a satisfying ride to a thrilling one." Edmunds tempers that criticism, saying that though the 2010 C70's performance is "certainly not blistering," the T5 engine "provides enough low-end torque to get the C70 moving briskly enough from a stop." Volvo states the C70's 0-60 mph acceleration at 7.6 seconds for the manual, and an even 8.0 seconds for the automatic.
Both gearboxes deliver smooth, easy shifts, and both pair well with the punchy turbo engine. The 2010 Volvo C70 will carry on to a top speed of 150 mph, yet still manages 18 mpg city and 27 mpg highway with the six-speed stick. The automatic rates 18/26 mpg. ConsumerGuide describes them both as "smooth," though noting that the "manual's shift action is a bit rubbery."
Handling is unexpectedly light, belying its hefty grand-tourer nature, and a tight feel to the steering and the whine of the turbo inspires. The electric power steering is a controversial element, but it's tuned for linear, realistic feel. The ride is well-controlled thanks to a MacPherson strut front-end and multi-link rear suspension.
Cars.com says the "C70 has sporty handling," though most find the car is better suited to grand touring duty than sports car slicing and dicing. Car and Driver explains, "the [Volvo] C70 had a tendency to wallow and pogo" on winding mountain roads, a result of suspension settings chosen for "boulevard ride quality." Kelley Blue Book says the 2010 Volvo C70 "does a more-than-creditable job of finding the ride balance between ride and handling for most luxury coupe-convertible drivers." ConsumerGuide agrees, pointing out that the Volvo C70 is "not sports-car nimble, but C70 corners with front-drive assurance, modest body lean and tolerable noseplow."
