Mercedes-Benz CLS 300
Car A
Mercedes-Benz CLS 300
Efficient for its class yet quick, the Mercedes-Benz CLS 300 diesel suits premium buyers who cover long highway miles and need real luggage space. Less compelling if you want winter-ready traction or SUV-like family flexibility.

Audi RS5 Sportback
A premium AWD sportback that pairs 450 hp and a 3.9 s 0-100 km/h sprint with five-seat practicality. Strong for fast road trips and winter use, but 10.5 combined consumption and cargo capacity that trails SUVs make it less ideal for city or cargo-heavy needs.
