Why Is the Caterham Seven 310 Encore Generating So Much Buzz?
If you’ve been following the world of lightweight sports cars, you’ve probably heard whispers—if not outright cheers—about the Caterham Seven 310 Encore. There’s a good reason for all the excitement. This isn’t just another limited-edition roadster; it marks the end of an era for Caterham and its beloved 1.6-litre Ford Sigma engine. For many enthusiasts, this car is more than a collector’s item—it’s a celebration of what makes driving pure, simple, and downright joyful.
What Makes the Ford Sigma Engine So Special?
Let’s talk engines. The 1.6-litre Ford Sigma has been a staple in Caterham’s lineup for years, and for good reason. It’s light, rev-happy, and delivers just the right amount of power for a car that weighs less than your average city hatchback. Back in 2012-13, the Sigma-powered Supersport was a favorite among drivers who craved sharp handling and a responsive throttle. I still remember a day spent at Rye House kart circuit, trying to see if any car could match the nimbleness of a go-kart. The verdict? Not quite, but the Sigma-powered Seven came tantalizingly close—and left a grin plastered on my face for days.
The Sigma’s charm lies in its balance. It’s lighter than the now-defunct 2.0-litre Ford Duratec, which means less weight over the front wheels and more agility in the corners. Compared to the tiny 660cc Suzuki engine in the Seven 170, the Sigma offers a satisfying bump in power without tipping into excess. It’s the kind of engine that encourages you to wring it out, rewarding smooth shifts and precise throttle inputs.
Why Is Caterham Switching to Horse Engines?
Change is inevitable, even in the world of classic sports cars. Ford stopped producing the Sigma engine years ago, and Caterham has been relying on a dwindling stockpile of parts to keep building cars. With supplies running low, the company needed a new partner. Enter Horse—a joint venture between Renault and Geely. Starting next year, Caterham’s Academy racing cars will be powered by Horse engines, marking a significant shift in the brand’s engineering DNA.
This isn’t just a logistical move; it’s a strategic one. By partnering with Horse, Caterham ensures a steady supply of modern, efficient engines that meet current emissions standards. It’s a smart play for the future, even if it means saying goodbye to an old friend.
What Sets the 310 Encore Apart from Other Sevens?
The 310 Encore isn’t just a send-off—it’s a love letter to the Sigma era. Caterham has pulled out all the stops for this special edition. The engine gets a tweak, pushing output to a lively 152bhp at 7000rpm. A lightened flywheel sharpens throttle response, while sports suspension keeps things planted through the bends. Only 25 examples will be built, each priced at £39,995.
But it’s not just about numbers. The Encore is designed to hit that elusive sweet spot between the featherweight Seven 170 and the fire-breathing 620. It’s the Goldilocks of the range—not too hot, not too cold, but just right for drivers who want a car that’s as happy on a twisty B-road as it is on a track day.
How Does the 310 Encore Compare to Other Caterhams?
Caterham’s lineup is famously diverse, ranging from the minimalist 170 to the outrageous 620. The 170, with its kei car-compliant Suzuki engine, is all about simplicity and low weight. The 620, on the other hand, is a rocket ship—brutally fast but not for the faint of heart. The 310 Encore slots neatly in the middle, offering enough power to thrill without overwhelming the senses.
This balance is what makes the Encore so appealing. It’s approachable for newcomers but rewarding for seasoned drivers. The limited production run only adds to its allure—owning one is like having a piece of Caterham history parked in your garage.
What Does This Mean for Caterham’s Future?
The move to Horse engines signals a new chapter for Caterham, but it doesn’t mean the end of the brand’s core values. Lightweight construction, driver engagement, and mechanical simplicity will remain at the heart of every Seven. If anything, the transition opens up new possibilities—modern engines with better efficiency, reliability, and compliance with ever-tightening regulations.
Industry experts agree that Caterham’s willingness to adapt is a sign of strength, not weakness. According to a recent report from the Society of Motor Manufacturers and Traders (SMMT), small-volume sports car makers face increasing pressure to update their powertrains. By getting ahead of the curve, Caterham is ensuring that the Seven will continue to delight drivers for years to come.
Is the 310 Encore the Ultimate Seven for Real-World Driving?
If you’re searching for a Seven that nails the balance between usability and excitement, the 310 Encore deserves a spot at the top of your list. It’s quick enough to keep you entertained, light enough to feel alive on every drive, and rare enough to turn heads at any car meet. For many, it’s the Goldilocks Seven—the one that’s just right.
And let’s be honest: there’s something special about owning the last of a breed. The 310 Encore isn’t just a car; it’s a celebration of everything that makes the Caterham Seven an icon. If you’re lucky enough to snag one of the 25, you’ll be driving a piece of history—one that’s sure to be cherished for years to come.
