Driving experience
Audi A6
Comfortable, quiet and genuinely refined. The A6 rides with excellent isolation, steers accurately with light weighting, and cruises with the calm composure expected of a large executive saloon. Front-drive versions are efficient; quattro adds traction and security. The 2.0 TFSI is smooth, the 3.0 TDI V6 is the long-distance workhorse, and the 55 TFSI e plug-in covers short trips on electric power. The S tronic is quick, the tiptronic smooth. It is a tech-heavy, comfort-first executive car that does long distances with little effort.
BMW 5 Series
Composed, refined and supremely effortless. Steering is precise and well-weighted, body control excellent, and the G30 blends limousine comfort with genuine driver involvement. sDrive keeps the classic rear-drive balance and composure; xDrive adds all-weather confidence without dulling the nose. Adaptive dampers and optional air suspension span cushioned to firmly controlled. The B48/B58 petrols are smooth and eager, the B47/B57 diesels pull strongly and stay hushed, and the 530e/545e plug-ins glide on electric power. The ZF 8-speed is quick, seamless and always in the right gear. Overall a polished executive saloon that turns a long drive into a calm, effortless one.
