Instrumented Test
From the January 2016 issue
When Mercedes married AMG in 2005 following a lengthy courtship, who would have expected that union to spawn 38 children? Not all those babies come to the U.S., but we do receive our share and more are on their way. The car on this page is the first middle child, a sports sedan badged Mercedes-Benz C450 AMG. It’s been reared to fill the void between regular Mercedes-Benz C-class models aimed at law-abiding citizens and the rowdy Mercedes-AMG C63.
Fret not over this C’s lack of a V-8. A new twin-turbo direct-injected 3.0-liter V-6 cranks out enough energy—362 horsepower, 384 pound-feet of torque—for the C450 to run with or past competitors such as the Audi S4, BMW 340i, Cadillac ATS, and Jaguar XE S. Aided by standard four-wheel drive, it bolts to 60 mph in 4.5 seconds and through the quarter in 13.1, just a few tenths of a second behind the 503-hp C63 S. Living with only a six-pack under the hood benefits mileage and chassis balance and drops the base price to $51,725—within reach of middle management.
The C450 has a nicely balanced performance portfolio. Panic stops from 70 mph in 160 feet rival the best competitors. The 0.93-g cornering grip is also exemplary, topping all BMWs lacking full M specifications. Thanks to a fixed 33/67-percent front/rear torque split, you can power out of bends in the wet without fear that the tail will slip first. Three-stage dampers handed down from the C63 provide body-motion control ranging from firm to extra firm, accessible via a console toggle.
“Discreet” best describes the C450’s exterior. There’s minimal AMG identification. But a megasized three-pointed star in the grille assures that no one will mistake this for a Suzuki.
Interior designers earned their keep by crafting one of the most nicely outfitted cabins on the market. The front buckets provide perfect restraint and long-lasting comfort without impeding ingress or egress. The rear bench seat coddles two and accommodates a third in a pinch.
Nice-to-touch steering-wheel paddles command the seven-speed transmission. While aggressive driving in automatic mode can elicit jerky downshifts, manual gearchanges are swift and smooth.
Unlike the stereotypical middle child, the C450 AMG is confident, comfortable, and rarely chooses a career in petty crime.
A fixed, non-touch center screen is your window to the C450’s nervous system. Key in the appropriate commands and you can fine-tune chassis and powertrain operations or display an entertaining power-and-torque gauge.
While leather is available at no extra charge, the MB-Tex vinyl upholstery is attractive and satisfying to touch. If you can live without the tanned-hide aroma, it’s worth a try. The only ergonomic flaw is a cruise-control stalk hidden behind a steering-wheel spoke.
The C450 AMG’s blend of performance, congeniality, and relative affordability suggests that Mercedes is on to something here. We say bring us more middle children.
