8.5/10 C/D RATING

Select a year

  • Highs Lag-free turbocharged four-cylinder, grippy handling, racier styling than standard C-class.
  • Lows Firm ride in all drive modes, new turbo four lacks character of the outgoing V-6, two-door models are being phased out.
  • Verdict The fun-to-drive C43 sedan serves as a sporty middle ground between the refined C300 and the visceral C63.
By Drew Dorian


The masterminds at Mercedes's AMG tuning arm have been set loose on the next-generation C-class and have created this all-new 2023 C43 sports sedan. This time around, the C43 makes due with two fewer cylinders and one less liter of engine displacement—but not less power—as AMG has swapped the old model’s 385-hp, 3.0-liter twin-turbo V-6 for a new turbocharged 2.0-liter four-cylinder engine pumping out 402 horses. All manner of performance enhancing tech is available on the C43, including rear-wheel steering and adaptive dampers for the aggressively tuned suspension. The C43's interior is similar to the new Benz-branded C300’s except, instead of looking like it attended finishing school, it appears to have graduated from a racing academy. Carbon-fiber trim covers most of the dashboard and the rest is faux-leather with contrasting stitching. A large, portrait-oriented infotainment tablet is angled toward the driver and runs the latest MBUX interface, but the thing driving enthusiasts will be looking forward to sampling is the C43's new heavily boosted four-cylinder, which uses turbocharger technology derived from Mercedes's F1 racing team and is similar to the one found in the SL43 convertible—a model that isn't sold in the United States.

What's New for 2023?

The C43 is completely redesigned for the 2023 model year and it should be at Mercedes dealers by the end of 2022. An even more powerful C63 model is coming and we know is that it too will be powered by a version of the high-strung 2.0-liter turbo-four.

Pricing and Which One to Buy

$63,000 (est)
$68,000 (est)
$73,000 (est)

    Unfortunately, we don't expect to see coupe and convertible models of the C43 this time around, although the previous generation C43 coupe and convertible remain in mix for the 2023 model year. When those are phased out, fans of two-door cars may find the SL-class or the CLE-class worthy replacements. Mercedes-AMG hasn't released pricing yet for the 2023 C43 sedan, but when they do we expect to see three distinct trim levels that match the Benz-branded C-class lineup.

    Engine, Transmission, and Performance

    While the outgoing model was motivated more than adequately by a 385-hp, 3.0-liter twin-turbo V-6, the 2023 C43 comes with a downsized turbocharged 2.0-liter inline-four. Not to worry: this new engine's power is anything but downsized, as it makes a healthy 402 horsepower and is assisted by a 48-volt hybrid system which can temporarily contribute up to 13 more ponies at lower rpm. (The hybrid assist doesn't add to the total power output, however.) The new engine's turbocharger setup is partially derived from the company’s F1 racing-engine tech. The turbocharger incorporates an auxiliary electric motor to spin up the compressor quicker, which in turn reduces turbo lag. A nine-speed automatic is standard—sorry to those who were hoping for a manual—and so is all-wheel drive, a rear-wheel steering system, and an adaptive dampers. Acceleration is brisk and during our initial test drive we were impressed with the four-cylinder's punch and lack of turbo lag. We estimate it should hit 60 mph in about 4.0 seconds, but we'll soon get the chance to test it for ourselves. The C43's handling is as spry as expected and cornering grip is ample. The tradeoff for that level of performance is a ride that's firm in even the softest drive mode setting.

    Fuel Economy and Real-World MPG

    The EPA hasn't released fuel economy figures for the 2023 C43 sedan yet. But despite the downsized engine, we're not expecting to see much change from the outgoing model which was rated for 19 mpg city and 28 mpg highway. When we get a chance, we'll take the new C43 sedan on our 75-mph highway fuel economy test route and update this story with its results. For more information about the C43's fuel economy, visit the EPA's website.

        Interior, Comfort, and Cargo

        Inside, the C43 mimics the Mercedes-Benz C300's cabin but gives it a sporty twist using racier materials such as optional carbon fiber trim. The C43 also comes with a sport steering wheel which features a flat bottom, a leather-and-suede wrap, and the AMG logo in the bottom spoke. Performance seats are available too, as is a panoramic sunroof, heated and ventilated seats, a heated steering wheel, four-zone automatic climate control, and noise-insulating window glass.

          Infotainment and Connectivity

          All models come with a large 11.9-inch infotainment touchscreen that is seamlessly integrated into the center console and canted slightly toward the driver. A 12.3-inch digital gauge display is also standard, and the system runs the latest MBUX software interface that allows for voice activation. Apple CarPlay and Android Auto should both be standard for wireless connectivity. A high-end Burmester stereo system is optional, as is a wireless smartphone charging pad, a head-up display, and in-dash navigation.

            Safety and Driver-Assistance Features

            Like the C-class, the C43 comes with a host of standard driver-assistance features but unfortunately the car's coolest tech, which includes an adaptive cruise-control system that utilizes navigation data to adjust the vehicle's speed for upcoming curves and roundabouts, is still optional. For more information about the C43's crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:

            • Standard automated emergency braking with pedestrian detection
            • Available lane-departure warning with lane-keeping assist
            • Available adaptive cruise control with a lane-centering feature

            Warranty and Maintenance Coverage

            Although rivals such as BMW, Genesis, and Volvo offer three years of complimentary maintenance, Mercedes-AMG omits that benefit from its standard warranty offerings. Otherwise, all new AMGs come with an industry-standard plan that covers most things for up to four years or 50,000 miles.

            • Limited warranty covers four years or 50,000 miles
            • Powertrain warranty covers four years or 50,000 miles
            • No complimentary scheduled maintenance
