Secret supercars from the 2017 Geneva Motor Show

From Ford to Ferrari, the Geneva motor show attracts the world's biggest car makers.

But it also draws in some of the smallest manufacturers from Europe, part of a decades-long tradition where boutique car makers and specialist tuners assemble small show stands to show off their low volume wares.

Here are some of the highlights from Geneva 2017, Europe's first major motor show of the year.

Ruf CTR

It may look like a 1980s Porsche 911 but the CTR – made by specialist Porsche modifier Ruf – is a very different beast. Despite the retro design that is based on the 1987 Ruf "Yellow Bird" (at a glance it looks very similar) the CTR is packed with technology.

For starters, there's a carbon fibre monocoque, the first time that production technique has been used on a rear-engine car (as opposed to mid-engine).

The 3.6-litre modified Porsche six-cylinder pumps out 522kW, more than enough in the featherweight 1200kg frame.

So it's considerably quicker than the Porsche it's based on, able to hit 200km/h in less than nine seconds.

Speedback GT

Those who love 1960s motoring will love the Speedback GT. It's produced by David Brown Automotive, a UK-based coachbuilder that conjures images of the David Brown whose initials grace many of Aston Martin's most famous models. But there's no connection between the two.

The company says the Speedback GT is not a remake of the iconic Aston Martin DB5 made famous by fictional spy James Bond, but rather a celebration of 1960s motoring generally. Still, there's plenty of DB5 in its beautifully crafted skin.

Underneath is a Jaguar XK platform and supercharged V8 Jag engine making 375kW.

The pre-tax price is about $800,000, so expect to pay about $1.2 million in Australia.

Mansory Gronos Black Desert

If the mighty Mercedes-Benz G-Wagen isn't enough for you, then how about the chunkier remake by German modifier Mansory.

Starting life as a 4x4² - with its higher ride height and additional off-road hardware – the Gronos Black Desert gets a wide-body kit made of carbon fibre, the first of many modifications that give the blocky 4x4 a sinister look.

To complete the OTT treatment the twin-turbo V8 has been boosted by 47kW to more than 300 in total.

Fittipaldi EF7 Vision Gran Turismo

Three years in the making and styled by Italian design house Pininfarina, the EF7 Vision Gran Turismo is a two-door supercar that bears the name of former F1 and Indy 500 champ Emerson Fittipaldi.

Now in his 70s, Fittipaldi was instrumental in bringing the modern race car for the road to life.

Just 25 of the V8-powered two-seaters are planned, each built around a carbon fibre tub with adjustable suspension.

No word on pricing yet, but expect it to be close to seven figures. For that you get access to exclusive driving and racing experiences with Emerson Fittipaldi. Or you could just buy the upcoming PlayStation game Gran Turismo Sport, where the EF7 will be one of the featured rides.

Fab Design Virium

If the prospect of a falcon-winged, all-electric Tesla Model S just isn't doing it for you then take it to Swiss-based tuning house Fab Design for some tweaking.

Known for its outlandish body kits, the team has developed a comprehensive kit that adds a hint of Ford Focus RS to the Model X's chunky stance. Massive 23-inch wheels top off the design modifications, which can add upwards of $40K to your Model X.

No changes to the electric motors, though, presumably because they already deliver potent acceleration.

Zenvo TS1 GT 10th anniversary

Ten years in and most wouldn't have heard of Dutch supercar maker Zenvo.

It's just produced a one-off version of its TS1 GT to celebrate a decade in (low volume) car production.

With a carbon fibre body and 5.8-litre V8 barking out 867kW the smurf blue two-seater launches to 100km/h in 2.8 seconds on the way to a top speed of 375km/h.
