Four-door performance machines that embarrass dedicated sports cars — the super saloon ranking
By Dream Car Garage Editorial
The super saloon represents one of motoring's great contradictions: a car designed to carry four adults and their luggage in complete comfort, yet capable of outperforming dedicated sports cars in a straight line and, in the very best examples, on a circuit as well. It is the performance car for people who have outgrown the compromise of a two-seat sports car but refuse to accept the performance penalty that family transport usually demands.
In 2026, the super saloon segment is defined by a transatlantic divide. On one side: American muscle in traditional RWD format, vast engines, and horsepower figures that would have seemed implausible a decade ago. On the other: European super saloons where AWD systems, electrified powertrains, and forensic chassis engineering produce cars of extraordinary breadth. Both approaches work. Both produce memorable machines.
Ranked by peak power output — the most honest measure of a super saloon's intent.
The third-generation CTS-V established Cadillac as a genuine rival to BMW M and Mercedes-AMG on the world stage — 640bhp from a supercharged V8 derived from the C7 Corvette ZR1, delivered with American directness and surprising finesse.
The E60 M5 housed a 5.0-litre V10 engine derived from BMW's Formula 1 programme — an engine that sang to 8,250 rpm and produced 717bhp in a four-door body. It remains the greatest naturally aspirated super saloon ever created.
797bhp from a supercharged 6.2-litre V8, rear-wheel drive, and a four-door body that seats five. The Charger Hellcat Redeye is Detroit's most extreme expression of muscle car logic applied to the family saloon format — and the result is magnificent.
The E63 S is the quintessential AMG weapon — 612bhp, a drift mode that disables the front axle for rear-wheel-drive hilarity, and a rear seat so civilised that your passengers will remain entirely unaware of what you are doing with their car.
The CT5-V Blackwing is Cadillac's masterpiece — a supercharged 6.2-litre V8 producing 668bhp, a six-speed manual gearbox, and handling calibration developed at the Nürburgring. The finest American super saloon ever created.
The F10 M5 marked BMW M's transition to turbocharged power with seamless results — 717bhp from a twin-turbo 4.4-litre V8, with an AWD system that kept the power manageable while a drift mode allowed it to be abandoned when the mood required.
The RS6 Avant proves that estate cars can be deeply desirable objects. At 600bhp with a mild-hybrid 4.0-litre V8, it carries the maximum European estate car load allowance while posting supercar 0–100 km/h times. The practical choice that feels anything but.
The GT 63 S 4-Door is AMG's most powerful four-door car — 630bhp from a 4.0-litre twin-turbo V8, delivered through a 4MATIC+ all-wheel drive system and a 9-speed multi-clutch gearbox that fires off gear changes with sporting intent.
AMG's most controversial decision — replacing the C63's V8 with a turbocharged four-cylinder hybrid — produced the most powerful C63 in history at 671bhp. The plug-in system delivers silent electric performance when required and explosive combined output when unleashed.
The standard Hellcat Charger pairs 717bhp with a supercharger whine audible three streets away. It is the most American car on this list in the most American sense — uncomplicated, enormous, and deeply committed to its single performance objective.
The super saloon is the segment that most consistently surprises non-enthusiasts. Nothing prepares a first-time passenger for the experience of a Dodge Charger Hellcat Redeye at full throttle, or the invisible speed at which a BMW M5 F10 crosses continents. These ten cars are daily drivers of extraordinary capability, practical enough for Monday and lethal enough for Saturday.
