Caterham 7 Specifications: The Numbers That Actually Matter
Caterham 7 specifications: why power isn't the full story
The Caterham 7 is a lightweight, rear-wheel-drive two-seater whose defining specification is not just engine output but the way very little mass turns modest horsepower into serious pace. Contemporary listings place one representative Caterham 7 at 1396 cc, 105 bhp, 128 Nm, 585 kg, 0-100 km/h in 6.5 seconds, and a top speed of 177 km/h, while newer Seven models are offered with roughly 84 bhp to 310 bhp and weights a little over 440 kg, showing how the platform's character changes more through mass and chassis tune than raw power alone.
What the Seven is
The Seven platform traces its identity to Colin Chapman's "simplify, then add lightness" philosophy, and that idea still explains the car better than any single horsepower figure. In modern form, Caterham sells the Seven as a family of variants with different engines, chassis sizes, and trim levels, but the core recipe remains the same: minimal bodywork, compact dimensions, manual control, and an emphasis on response rather than isolation.
That is why a Caterham 7 can feel quicker than much faster-seeming cars on paper. A machine that weighs around half a tonne does not need huge power to feel urgent, because every extra bhp has less mass to move, and every steering or throttle input produces a more immediate reaction than in a heavier sports car.
Core specifications
Specifications vary by trim and market, but the classic spec sheet for a Caterham 7 typically reads like a stripped-back performance car rather than a grand tourer. One widely listed example shows a 1396 cc petrol engine, manual transmission, two-cylinder layout in the listing, 105 bhp at 6000 rpm, 128 Nm at 5000 rpm, a 60-litre fuel tank, rear-wheel drive, and a kerb weight of 585 kg.
| Specification | Representative Caterham 7 figure | Why it matters |
|---|---|---|
| Engine displacement | 1396 cc | Small capacity helps keep the car light and responsive |
| Max power | 105 bhp @ 6000 rpm | Enough for brisk acceleration in a very light car |
| Max torque | 128 Nm @ 5000 rpm | Midrange pull matters more than peak power in real driving |
| Kerb weight | 585 kg | Low weight is the Seven's biggest performance advantage |
| 0-100 km/h | 6.5 seconds | Shows how little mass needs to be accelerated |
| Top speed | 177 km/h | Useful, but acceleration and feel are the real appeal |
| Drivetrain | RWD, manual | Maintains direct control and classic sports-car behavior |
Power versus weight
The power-to-weight ratio is the Seven's real headline figure, and it explains the car's reputation better than horsepower alone. A 150 bhp Caterham cited in period reporting was described at around 270 bhp per tonne in Roadsport form and about 300 bhp per tonne in lighter Superlight form, with 0-60 mph times of roughly 4.9 seconds and 4.6 seconds respectively.
Even the same engine can feel dramatically different depending on trim, because a 50 kg weight saving changes acceleration, braking, cornering, and ride quality all at once. That is why modern Seven variants advertised at about 440 kg with up to 310 bhp look so extreme on paper: the car is being developed around the idea that reducing mass can be as valuable as adding power.
"The Seven's lightweight design pairs effortlessly with a range of engine options," Caterham says in its model overview, which is a concise summary of the car's engineering logic.
Dimensions and packaging
The compact dimensions are central to the Seven's behavior on road and track. A representative specification lists the car at 3340 mm long, 1397 mm wide, 1105 mm high, with a 2235 mm wheelbase, 100 mm ground clearance, and two seats only.
Those numbers matter because a short wheelbase makes the car agile, a narrow body reduces frontal area, and a low stance helps aerodynamic drag and center of gravity. Other market data for later Seven variants shows widths around 1700 mm, heights around 1120 mm, and lengths from 3360 mm to 3530 mm depending on model, so the Seven remains tiny by modern sports-car standards even as Caterham broadens the range.
- Two-seat cockpit, focused on the driver and passenger only.
- Rear-wheel drive for traditional handling balance.
- Manual gearbox, typically five-speed in the listed example.
- Very low kerb weight, typically around 440 kg to 585 kg depending on trim and source.
- Small footprint that makes the car look almost kart-like in traffic and on circuit.
Chassis and suspension
The chassis setup is a major reason the Seven feels so alive at low and medium speeds. One published specification lists adjustable double wishbone front suspension with an anti-roll bar, a De Dion rear axle located by a lower A-frame and upper radius arm, rack-and-pinion steering, and disc brakes front and rear.
That hardware gives the Seven unusually clean feedback through the steering wheel and seat, especially compared with heavier cars that rely on larger tires, power steering calibration, and more complex electronic intervention. In practice, the Seven's suspension geometry and low mass make the car communicate changes in grip very clearly, which is why drivers often describe it as more engaging than faster machines.
Performance character
The performance story is less about top-end speed and more about immediacy. A 135 bhp Caterham Seven 270 was reported at about 5.9 seconds to 100 km/h and 205 km/h top speed, while a 1.6-litre Super Seven with 135 bhp and 540 kg was tested at exactly 5.0 seconds to 62 mph and a 122 mph top speed.
That split between acceleration and top speed is typical of the Seven family. The car is engineered to feel explosive out of corners, easy to place on a narrow road, and richly communicative through chassis movement, even when the absolute speed is not supercar-level.
- Check the power figure, but compare it with weight first, because the Seven's pace is mass-dependent.
- Look at torque delivery and rpm range, because a lighter Caterham rewards accessible midrange shove more than peak numbers.
- Compare chassis variants, since SV and standard chassis choices affect comfort and fit as much as performance.
- Consider the gearbox and suspension tune, because these shape the car's feel more than headline speed.
Model range context
The modern range stretches from accessible entry models to highly tuned specials, and that breadth is one reason "Caterham 7 specifications" is not a single answer. Caterham's current Seven lineup spans engine outputs from about 84 bhp to 310 bhp, which means the platform can be tuned for road use, weekend blasts, or serious track work without losing its basic identity.
Older and specialist versions show how far the formula can be pushed. Period examples include a 150 bhp Ford Sigma-powered Seven with around 270 bhp per tonne in Roadsport trim and 300 bhp per tonne in Superlight trim, while more recent road-focused variants emphasize balancing power with a low curb weight to preserve the car's core feel.
Why enthusiasts care
The enthusiast appeal comes from how the Seven translates engineering into sensation. In a heavy sports car, a bigger engine often feels like the main event; in a Caterham, the engine is only one part of a broader package where steering weight, chassis flex, tire contact, and driver visibility all matter just as much.
That is why the Seven's specifications are best read as a system, not a list. The numbers tell you it is light, narrow, manual, and rear-driven, but the real result is a car that rewards commitment, precise inputs, and mechanical sympathy far more than brute force.

Why does the Caterham 7 feel faster than it is?
The car feels faster because it is extremely light, so even modest horsepower delivers a strong power-to-weight ratio, sharp acceleration, immediate steering response, and minimal insulation between driver and road.
Is more power the main upgrade for a Caterham 7?
More power helps, but weight reduction, suspension tuning, gearing, and chassis choice often produce a bigger real-world change in character than a simple horsepower increase.
What makes the Seven different from other sports cars?
The Seven is different because it is intentionally minimal, with two seats, very low mass, manual control, and a design that prioritizes feedback and agility over luxury or isolation.
