GENEVA MOTOR SHOW: Alpine A120 firms

Renault's Alpine brand has officially announced that it will reveal its first car in more than two decades on March 7.

Releasing a 'Save the Date' teaser on its official website overnight, the new mid-engine coupe follows a long and drawn-out 12 month teaser campaign triggered by the unveiling of the original Alpine Vision concept last year.

While the production version is yet to be named, speculation suggests it will be called the A120.

So far, we have seen disguised production cars drifting in a video, been shown the bare lightweight aluminium structure that it will be based on and even had its advanced aerodynamics aids explained.

What we haven't seen is a clear picture of the actual car.

What we do know, so far, is the unnamed French coupe will be among the lightest in its class, tipping the scales at around 1100kg – some 200kg lighter than the Porsche Cayman.

It will also come powered by a mid-mounted 1.8-litre turbocharged four-cylinder engine developed by 'Renaultsport' and rated at up to 225kW, most likely matched to a dual-clutch automatic transmission.

With a sophisticated launch control in place, the A120 should easily meet Alpine’s target performance figures of a 0-100km/h time of no more than 4.5 seconds.

Prospective buyers have already been invited to place a €2000 ($A2800) deposit via a downloadable Alpine app to reserve one of the 1955 Premiere Edition coupes that will be priced between €55,000-€60,000 ($A75,000-$A84,000) in France, inclusive of tax.

Deliveries Down Under are expected to begin in 2018.
