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.
