Caterham Seven 170 – Light Is Right

Caterham’s lightest and smallest version of the legendary Seven sports car to date the 170 offers feisty fun and fuel efficiency by equal measure. Weighing in at just 440kg in its most basic specification, the Seven 170 is lighter than the batteries of many a bloated, boring EV. Successor to the Seven 160, the 170 is powered by a more powerful version of the same tiny turbocharged Suzuki-sourced 660cc 3-cylinder engine and rides on slim 155-section tyres. Developing 84BHP and in excess of 170BHP per tonne, the 170 promises 6.9-second 0-97km/h acceleration and is now available in road S and track-oriented R versions.

– Press Release –


  • If you follow our monthly newsletter (and if not, you should), you may have noticed that as a tenacious British brand, recent world events haven’t slowed us any.
  • Like a small undernourished golden phoenix rising from the depths of COVID riddled news, comes our latest incarnation of the beloved Seven – The new Caterham Seven 170

23 September 2021, UK – Following in the demure footsteps of its predecessor, the Seven 160, and complying with Japan’s world-famous Kei car regulations, the Seven 170 weighs in at as little as 440kg, making it our lightest production Seven of all time!

Not only is it light, it’s also small. With new front and rear wings, it measures just 1470mm in width, (that’s a whopping 105mm narrower than anything else), making it also, our smallest current Seven.

Holding true to the mantra that spawned the original Seven, to “simplify and add lightness”, while remaining as light as possible, we’ve ensured we protect that which has kept the Seven name alive for years – the driving experience!

Thanks in large part to a new addition in our engine line up, a 660cc turbocharged 3-cylinder Suzuki engine, which produces not only 84bhp but also 116nm of torque, the Seven 170 boast an insanely balanced power to weight ratio which exceeds 170bhp-per-tonne, and we’re quite excited to see and hear what you have to say about it.

But what’s power and weight without a little ‘lively-ness’?

Married to this little whippersnapper, are both live rear axle suspension and some uniquely ‘skinny’ Avon ZT7 tyres (a 155-section tyre), which when combined guarantees all those who dare win, through accessible performance regardless of age or driving ability.

Available in the customary S variant and for the first time, in this heady concoction, an R too, the Seven 170 pushes that which was great about the entry-level Seven 160 and then some.
