Caterham Super 7 Specs: Tiny Car, Massive Thrills
The Caterham Super 7 is a modern-interpretation, open-wheeled roadster built around minimal weight, highly responsive dynamics, and a choice of punchy four-cylinder engines. Depending on the variant, a typical Super 7 delivers between roughly 84-180 bhp while keeping curb weight under 600 kg, resulting in 0-62 mph sprints from about 6.5 seconds down to roughly 4.0 seconds and top speeds ranging from around 105 mph for the smallest 660 cc Suzuki engine up to roughly 130 mph for the 2.0 litre Ford Duratec option.
Sold as a kit or factory-built unit, the Super 7 is offered in several engine configurations including both the globally homologated 660 cc Suzuki and the larger 2.0 litre Ford Duratec units. Each configuration is tuned to exploit the extremely low kerb weight and abbreviated footprint, making acceleration feel dramatically quicker than the raw horsepower figures might suggest.
Core Caterham Super 7 Performance Specs
A modern Caterham Super 7 typically features a front-mounted, naturally aspirated four-cylinder engine driving the rear wheels through a five-speed manual transmission. Across the range, power outputs are modest by supercar standards, but the cars' mass-to-power ratios are often in the 3-4 kg/hp window, which is comparable with some high-end sports cars.
Typical headline figures for the Super 7 family include:
- Engine layout: Front-mid, longitudinally mounted four-cylinder, rear-wheel drive.
- Kerb weight: Roughly 540-580 kg depending on chassis version and engine fitment.
- Power output: 84 bhp (660 cc Suzuki) up to around 170-180 bhp (2.0 litre Ford Duratec).
- 0-62 mph (0-100 km/h): Approximately 6.5 seconds for the 660 cc version and around 4.0-5.0 seconds for the 2.0 litre Duratec-equipped cars.
- Top speed: In the 105-130 mph range, again depending on engine and gearing.
Comparative Performance Across Engines
The Caterham Super 7 product line effectively splits into three broad performance tiers: the budget-oriented 660 cc Suzuki, the mid-range 1.6 litre Ford Sigma-based units, and the more muscular 2.0 litre Ford Duratec engines. Each tier is tuned to deliver a different balance of torque, soundtrack, and track-friendly punch.
The following table illustrates representative performance specs for key Super 7 variants as sourced from Caterham brochures and independent tests. These figures are indicative and may vary slightly by model year and market specification.
| Variants | Engine | Power | Weight | 0-62 mph | Top speed |
|---|---|---|---|---|---|
| Super 7 660 | Suzuki 660 cc inline-4 (turbo) | 84 bhp (63 kW) | ≈540 kg | ≈6.5 s | ≈105 mph (168 km/h) |
| Super 7 1600 | 1.6 l Ford Sigma 16-V | 137 PS (≈101 kW) | ≈540 kg | ≈5.0 s | ≈122 mph (196 km/h) |
| Super 7 2000 | 2.0 l Ford Duratec 16-V | ≈170 bhp (127 kW) | ≈580 kg | ≈4.0-4.3 s | ≈130 mph (209 km/h) |
These combinations deliver power-to-weight ratios in the range of roughly 130-160 bhp per tonne, which is enough to provide roll-the-throttle-anywhere responsiveness and a vivid sense of acceleration even at higher speeds.
Chassis, Suspension, and Braking
The Super 7 chassis is based on Caterham's bonded-and-riveted aluminium spaceframe, which is an evolution of the original Lotus Seven design. The front suspension employs double wishbones with coil springs and adjustable dampers, while the rear uses a located de Dion tube setup with coil springs and dampers, tuned to maintain sharp turn-in and stable straight-line performance.
Braking is handled by lightweight disc systems at all four corners, with larger front discs and performance-oriented pads to cope with repeated track use. The absence of ABS and traction control forces the driver to modulate the rear-wheel drive system and pedal inputs manually, which strongly enhances the car's analogue feel.
Aerodynamically, the Super 7 relies less on downforce and more on low mass and mechanical grip. Drag coefficients are not officially published for many variants, yet test data and independent reviews suggest that the combination of short bodywork, open wheels, and modest frontal area keeps high-speed drag manageable despite the retro styling cues.
Driving Experience and "Real-World" Performance
Owners and professional testers consistently describe the Caterham driving experience as "raw" and "immediate," with every steering input, throttle change, and braking modulation translated directly into chassis response. Because the car weighs roughly the same as two adult passengers, drivers report that even modest engine tunes feel brutally fast on tighter roads.
In practice, the Super 7's 0-62 mph figures are only part of the story. The narrow track and short wheelbase amplify the sense of lateral force, while the high-recirculating steering ratio sharpens turn-in and mid-corner feedback. Many reviewers note that the car feels equally at home on a private B-road or a small circuit, where its ability to rotate freely and maintain pace through slow-speed corners more than compensates for its limited outright top speed.
Typical Fuel Economy and Emissions
The fuel economy of the Caterham Super 7 varies by engine and driving style, but published figures for the 660 cc Suzuki variant show CO₂ emissions around 109 g/km, while the 2.0 litre Ford Duratec version clocks in at approximately 148 g/km. These CO₂ numbers translate roughly into mid-30s to low-40s mpg under mixed driving conditions, although spirited running can easily cut efficiency by a third or more.
Because the Super 7 is designed as a lightweight, enthusiast-focused machine rather than a family sedan, fuel-tank capacity is modest-often in the 35-40 litre range-so long-distance touring requires careful planning of refuelling stops.
Technical and Historical Context
Evolution from the Original Lotus Seven
The Super 7 line traces its roots back to the original Lotus Seven introduced in the late 1950s, which was also a lightweight, open-wheeled, front-engine roadster. When Caterham acquired the rights to the Seven design in 1973, it continued to refine the chassis and drivetrains, culminating in the modern Super 7 family as a deliberate nod to that heritage.
Historically, early Super Seven models such as the Sprint used small four-cylinder powerplants like the 1.6 litre Ford Kent, producing around 109 horsepower and capable of topping roughly 106 mph with curb weights just above 500 kg. These figures laid the groundwork for today's Caterham ethos: minimal mass, maximum mechanical feedback.
Modern Super 7 Engines and Tuning
The current Super 7 range employs two main engine families: the compact, turbocharged Suzuki 660 cc unit and the naturally aspirated Ford Duratec 2.0 litre. The 660 cc Suzuki offers a playful, torquey character suited to UK-spec licensing and crowded roads, while the 2.0 litre Duratec provides a broader powerband and higher peak output for track-leaning owners.
Independent tuning firms and Caterham specialists have documented power gains of roughly 10-15% on 2.0 litre Duratec units with simple bolt-on modifications, including high-flow intakes and exhaust systems. Such upgrades can push power beyond 190 bhp without materially increasing weight, sharpening the car's already aggressive mass-to-power ratio.
Buying and Owning a Caterham Super 7
Current Caterham pricing places base Super 7 models such as the 660 in the mid-30,000-pound region, with the 2.0 litre 2000 variants typically starting around the 40,000-pound mark before options. Factory assembly and extra equipment such as bespoke paint, upgraded seats, or race-oriented suspension can push prices several thousand pounds higher.
From a maintenance perspective, the rotating assembly in Ford-based engines is generally regarded as robust, especially when serviced to time and mileage rather than pushing extended track sessions without proper cooling and oil changes. Suspension and brake components are relatively simple by modern standards, which can reduce repair costs but also demands more frequent manual inspection of fasteners and adjusters due to the car's intensive use profile.
