The Alpine A110S has made its public debut at Tokyo motor show, having first been revealed in August.
The flagship model, which went on sale in September, is priced from £57,590 in the UK, including the cheapest paint option.
The S commands a £6780 premium over the mid-range Légende variant, and can be specced in a range of five colours, the most expensive of which, matt grey, costs £4440. A new set of 18in black alloy wheels is exclusive to S trim, and a contrasting carbon roof can be equipped for £2208.
Inside, the standard leather-Alcantara sports seats can be replaced with a pair of carbon-backed buckets for £1656, while bespoke floormats with blue stitching can be added for £110.
Driving aids such as hill start assist, cruise control and tyre pressure monitoring are equipped as standard, but a rear parking camera is optional at £480.
The new A110 S is, according to the company, a true “focused sports car” with a “very different character” from existing versions of the two-seater.
The new range-topping variant of the mid-engined Alpine is built around a reworked version of the 1.8-litre four-cylinder turbocharged engine, with the turbo boost pressure increased by 0.4 bar.
That means the unit’s peak power output has risen by 49bhp to 288bhp, which arrives at 6400rpm, 400rpm higher than previously. Torque remains at 236lb ft but is available from 2000rpm to 6400rpm, 1400rpm higher than in a standard A110.
Retaining the seven-speed automatic gearbox from the standard Alpine, the A110 S can cover 0-62mph in 4.4sec – a 0.1sec improvement – and its top speed is 162mph. The A110 S retains the same aluminium body but has a different chassis configuration, with new stiffer coil suspension springs, retuned dampers and firmer anti-roll bars.
The ride height has been lowered by 4mm to increase stability. There are new wheels and new bespoke Michelin Pilot Sport 4 tyres (215mm at the front, 245mm at the rear) for increased mechanical grip. Brembo brake calipers with 320mm bi-material discs – available as an option on other A110 variants – are standard and the firm has reworked the electronic stability control.
Overall, the changes have increased the car’s weight slightly, from 1103kg to 1114kg. Jean-Pascal Dauce, Alpine’s engineering boss, said the changes were all designed with a focus on “high-speed stability and handling precision”. But he added that it would remain a “usable everyday car. The A110 S wouldn’t be a true Alpine if it was too firm or too hard riding to be driven day to day.”
