Alpine A110 first ride: will it be a Porsche 718 Cayman beater?

Alpine A110 driven

Alpine’s bold intention for its new A110 is to create a lightweight sports car to rival the Porsche 718 Cayman on track while remaining comfortable every day on the road

We’ve seen the Alpine A110 production car – the model that revives the famous Alpine name – on the show stand at Geneva and we’ve learnt all about its technical specifications, but we won’t actually drive the car until October. However, I have just spent a day riding in it at Renault’s Aubevoye test facility in the north of France. 

Before I was allowed to belt myself into the A110’s fixed-back bucket seat, Chief Engineer David Twohig and Product Planning Director Eric Reymann took a few minutes to set the scene. “We started doing some customer clinics as far back as 2012,” says Reymann, “first with pure car guys, people who owned specific Porsches, Caterhams or Lotuses, and then with everybody else. We found there was an appetite for a sports car that could be comfortable to use every day, but that was also fun on the circuit.”

“We wanted to build a car that was a pleasure to drive on the road at 40mph,” adds Twohig, “but still bloody good when you go and do a track day every couple of months.” From there, Twohig and his team defined the A110’s technical specifications, placing lightness front and centre. 

“If the car is light,’ he continues, “that allows you to bring the spring rates down, so you don’t have a super stiff car that’s a pain to drive every day. That’s why the A110’s body is made from aluminium. 

“The second important thing is the suspension set-up. We’ve got double wishbones all-round, which is very unusual in this class. The 718 Cayman, for instance, has MacPherson struts on its front axle.”

It’s worth revisiting chapter one of the vehicle dynamics textbook here, because those double wishbones, as well as the lightweight build, really do underpin every one of the A110’s dynamic characteristics. Double wishbones allow the engineers to control wheel camber in hard cornering, whereas a less sophisticated strut arrangement does not. By controlling wheel camber, you’re keeping the tyre contact patch flat to the road surface, rather than allowing it to ‘fall over’ into positive camber, where it can’t grip effectively. 

In a car with strut suspension, that can be achieved by fitting whacking great anti-roll bars to stop the body from leaning over in a bend. But that simply ruins the ride quality. 

“Because we have double wishbones all-round,” explains Twohig, “we don’t have to fight against the body roll. That’s why the A110 uses very small, hollow anti-roll bars, which are really good for the ride.”

With weight kept to a minimum – just 1080kg at the kerb – and that double wishbone layout, the foundations of a good sports car are in place. The A110 should be agile and grippy (even on its relatively modest Michelin Pilot Sport 4 tyres), with a pliant ride quality and good body control. Everything else should simply follow along from there.

Let’s dive a little deeper. The A110’s suspension arrangement, says Twohig, gives it best in class camber linearity. That makes it progressive at the limit rather than spiky and unpredictable. Furthermore, in really hard cornering, the toe angle adjusts to slight toe-out, which gives gentle understeer characteristics, meaning there’s a safety margin built in. The basic chassis balance can therefore be tuned to be quite neutral, or even oversteery. All of that makes for a car that’s fun and adjustable at low and medium speeds, while also being stable and secure at high speeds. We call that the Holy Grail. 

It’s worth noting, though, that double wishbone suspension isn’t without its drawbacks, mostly relating to packaging. A strut arrangement would have enabled a bigger front storage compartment. It’s encouraging to know Alpine’s priorities are as they should be. 

There aren’t many people on this earth better equipped to demonstrate the A110’s dynamic ability than Laurent Hurgon, and there can’t be many better places to experience the car right on the limit than Aubevoye’s high-speed test track. Hurgon, the French racing and development driver, pilots the A110 with such commitment and ability around the flowing track – which links terrifyingly fast bends with tight, complex corners – that I can hardly believe I’m riding in a car so dainty and benign looking. This thing feels like a wild animal. 

Straight-line performance is strong and there’s even an authentic sports car soundtrack to go with it, while the double-clutch gearshifts feel sharp and snappy. The Track ESC mode allows a certain amount of slip – enough that the car will drift slightly in low-speed corners but not beyond that – and with the systems switched off entirely, the car will hold long, lurid and very progressive slides. It also feels amazingly agile and responsive in direction changes while being safe and stable at high speed. 

Over rougher sections of the test facility – by which I mean surfaces that would cause many cars to leap clean over the perimeter fence – that pliant ride quality is very plain to see. I don’t know of many cars that combine body control and ride quality as well as this. 

Does any of that actually make the A110 fun to drive? We won’t know until we drive the car later in the year. I am now more confident than ever, though, that the Alpine will have what it takes to give the mighty Porsche 718 Cayman an equally mighty scare.
