That’s a pretty wide gap in performance between the two, considering the specific outputs, but Mercedes will reportedly fill this gap with a new mid-range model called the C450 AMG Sport. According to Autocar, the new C450 AMG Sport will arrive next year and offer Mercedes fans a rival to the likes of the Audi S4 and BMW’s upcoming M Performance 3-Series.
Power in the C450 Sport is said to come from an uprated version of the C400’s turbo V-6, with the final output likely to lie close to 367 horsepower. The car should also benefit from sport suspension and a number of AMG-developed performance parts such as the sporty AMG Line aero kit, AMG light alloy wheels, and AMG interior upgrades.
Unlike the new C63 AMG, which is expected to remain a rear-wheel-drive vehicle, the C450 AMG Sport is expected to offer 4MATIC all-wheel drive as an option.
