Introduction

The Caterham Seven 170 is a modern marvel of lightweight engineering, taking a different approach to sports cars compared to the high-powered machines we typically see today. Powered by a small yet efficient Suzuki engine, this version of the Caterham challenges everything you thought you knew about performance. With only 84 horsepower, the 170 delivers a thrilling, adrenaline-packed driving experience, proving that less can sometimes be more.
In a world where bigger is often seen as better, the Caterham Seven 170 flips that narrative. It’s economical, environmentally friendly, and surprisingly fun. Let’s dive into why this sports car should be on every driving enthusiast’s radar.

A Distillation of Caterham’s Philosophy

Caterham’s mantra has always been about simplicity and lightness, and the Seven 170 is the purest expression of this philosophy. Caterham claims that this model encapsulates everything the brand stands for: accessible, lightweight sports cars designed for maximum driving pleasure. Despite its modest power, the car’s weight (or lack thereof) allows it to keep up with modern hot hatches, offering a driving experience that is unlike anything else on the market.
The Seven 170 is powered by a tiny 660cc turbocharged engine from Suzuki. On paper, the output of 84 horsepower might not seem like much, but the car’s total weight is just over 440 kilograms. This gives it an impressive power-to-weight ratio of over 170 brake horsepower per tonne. As a result, the 170 can sprint from 0 to 62 mph in just under 7 seconds and reach speeds over 100 mph. That’s more than enough speed for a car of this size.

Driving the Caterham Seven 170

For those who have never driven a Caterham, the experience can feel overwhelming at first. Unlike many modern sports cars that insulate you from the road, the Seven 170 offers an incredibly raw, organic experience. When you turn the tiny steering wheel, you can see the front wheels responding beneath their cycle mudguards. Hit a bump, and you’ll witness the suspension at work, a reminder that every aspect of the car is designed for feedback and control.
Driving down a country lane at 40 mph feels like you’re flying, offering a full-strength adrenaline rush that few other cars can match. Despite the small engine, the Seven 170 delivers the proper Caterham experience, proving that you don’t need a large power plant to have fun.

Lightweight Engineering at its Finest

The 170’s magic lies in its weight—or rather, its lack of it. By adhering to Colin Chapman’s famous philosophy of “simplify, then add lightness,” Caterham has managed to build a car that feels nimble and eager at all times. The Suzuki engine may produce just 84 horsepower, but the combination of that power with the car’s ultra-low curb weight delivers performance that can easily embarrass more powerful sports cars.
The suspension setup, including a live rear axle, along with 155-section tires, ensures that drivers of all skill levels can extract the full potential of this car. There’s no electronic traction control here—it’s all up to your right foot. The steering is weighty yet communicative, and the brakes have enough bite to make you feel like you’re hanging off your seatbelt during heavy deceleration.

Compact, Yet Full of Character

The Seven 170 is not only the lightest Caterham ever produced but also the narrowest. It measures just 1,470 millimeters in width, making it 105 millimeters narrower than anything else in the range. This small size makes it ideal for tackling tight corners on winding roads or zipping through city traffic.
Externally, the 170 features new alloy wheels, rear LED lights, and a sharper stripe design, all adding to its quirky charm. However, don’t expect it to be practical—this is a car built for driving pleasure, not for running errands. There’s no radio, and the ergonomics, while improved, are still reminiscent of the 1970s. But for those who appreciate purity in their driving experience, these quirks are part of the appeal.

Track-Ready or Road-Ready? Your Choice

Caterham offers the 170 in two versions: the 170S and the 170R. The 170S is designed for more laid-back, road-focused drivers, equipped with a five-speed gearbox, softer suspension, a full windscreen, and weather gear including a hood and side screens. It also comes with leather seats and a Momo steering wheel, offering a touch of luxury for those who want to enjoy their Sunday drives in comfort.
On the other hand, the 170R is for those who live for the track. It comes with stiffer sport suspension, a limited-slip differential, and composite race seats with four-point harnesses. The interior is stripped back, featuring a carbon-fiber dashboard and minimal creature comforts. Both variants offer excellent value, starting from around £25,000, making the Seven 170 a relatively affordable entry into the world of track-capable sports cars.

Economy and Running Costs

One of the often-overlooked benefits of the Caterham Seven 170 is its affordability when it comes to running costs. Due to its lightweight construction, this car is incredibly easy on consumables such as tires and brakes. Components last longer because they aren’t subjected to the same forces as they would be in heavier vehicles.
Fuel economy is another strong suit of the 170. Even with spirited driving, it’s common to see an average of 30 to 35 miles per gallon. The car’s small engine makes it one of Caterham’s most environmentally friendly models, with CO2 emissions of just 109 grams per kilometer. It’s even ULEZ-compliant, making it greener than many hybrid vehicles on the market today.

Conclusion

The Caterham Seven 170 stands as a testament to the enduring appeal of lightweight sports cars. In a world where performance is often defined by horsepower and high-tech gadgetry, the 170 reminds us that sometimes, the best driving experiences come from simplicity. With its nimble handling, economical engine, and unique driving feel, this car delivers pure fun, even without massive power numbers.
