Performance, power and 0-100 km/h
Both cars record the same 0-100 km/h time of 6.0 seconds. 2025 Genesis G80 2.5T AWD has the higher listed output at 300 hp; 2025 Mercedes-Benz C-Class C 300 4MATIC is rated at 258 hp, a difference of 42 hp. The torque figures follow 2025 Genesis G80 2.5T AWD at 422 Nm and 2025 Mercedes-Benz C-Class C 300 4MATIC at 400 Nm. These figures describe straight-line potential only; they do not establish braking performance, ride quality, steering response or durability under repeated hard use.
Range, battery, charging and efficiency
2025 Mercedes-Benz C-Class C 300 4MATIC has the lower recorded consumption at 7.6 L/100km; 2025 Genesis G80 2.5T AWD is listed at 8.8 L/100km. Test cycle, temperature, wheel size and charging conditions can materially affect these results, so only figures measured on the same basis should be treated as directly comparable.
Dimensions, cargo space and towing
2025 Mercedes-Benz C-Class C 300 4MATIC provides the larger quoted cargo volume: 455 litres versus 424 litres, a difference of 31 litres. 2025 Genesis G80 2.5T AWD is 244 mm longer overall. Exterior size is not a benefit by itself: a longer body may create useful room, but cargo shape, rear-seat space and ease of parking still require a physical inspection.
Price and overall assessment
2025 Mercedes-Benz C-Class C 300 4MATIC has the lower listed starting price at $45,400, compared with $54,150 for 2025 Genesis G80 2.5T AWD. 2025 Mercedes-Benz C-Class C 300 4MATIC leads in more of the shared headline fields, but that is not a universal verdict: a buyer should weight price, performance, range and utility rather than simply count category wins. The assessment is based on the specifications shown here; it is not presented as a two-car road test.
