Vauxhall Astra GTC: more details revealed

GTC to secure 20% of all Astra sales in the UK

Vauxhall Astra GTC

Vauxhall is looking to steal sales from the VW Scirocco and Renault Megane Coupé with the Astra GTC

Vauxhall has revealed further details of its new Astra GTC – a three-door coupé aimed at the same market as the Volkswagen Scirocco and Renault Mégane Coupé.

With looks strikingly similar to last year’s GTC Paris concept car, the Astra GTC seems certain to turn plenty of heads, while also offering strong value for money and a chassis that was tuned on UK roads.

New Vauxhall Astra GTC: surprisingly different

The new GTC is the third Astra model variant of this generation – following on from the five-door hatchback and Sports Tourer estate.

The GTC shares just the door handles and roof aerial with the current Vauxhall Astra hatchback

The family resemblance is clear, but in fact everything bar the door handles and the roof aerial is different on the GTC – including the wheelbase and the width of the track, which is wider by 40mm at the front and 30mm at the rear.

Despite its dramatic appearance, Vauxhall is promising the Astra GTC offers increased practicality compared to the competition. It will – apparently – seat four adults in comfort, while boot space ranges from 370 litres with the rear seats in place to 1,235 litres with them folded.

There’s also a 50% increase in storage volume within the cabin compared to the previous Astra three-door, the Sport Hatch.

Chassis and suspension tuned on UK roads

Vauxhall believes the GTC will account for 20% of all Astra sales in the UK

The UK is expected to be the biggest market for the Astra GTC, with the car predicted to secure 20% of all Astra sales here.

For this reason, Vauxhall has paid special attention to tuning the Astra GTC’s chassis for the unique challenge of British roads, utilising the Vauxhall Engineering Centre based at the Millbrook test track. The car features suspension similar to other Astras at the rear, but borrows its front suspension design from the high performance Insignia VXR.

Compared to the regular Astra Hatch, the GTC’s ride height is 15mm lower. Together with the wider track and the option of 20-inch alloy wheels, this should increase both stability and excitement; even the entry-level Sport specification includes 18-inch alloys as standard.

Those wishing to take things even further will have the option of adding Vauxhall’s FlexRide adaptive damping for an additional cost, giving the choice of Standard, Tour and Sport settings.

Turbo power, with VXR hot hatch to follow

A VXR version of the Vauxhall Astra GTC is due later

Engines for the Astra GTC consist of three petrol units and one diesel – all of them turbocharged.

Two versions of Vauxhall’s familiar 1.4-litre Turbo petrol are offered, with 118bhp or 138bhp. Start-stop technology and six-speed gearboxes mean both emit 139g/km CO2, while returning a claimed 47.9mpg combined.

Above these sits a 1.6-litre Turbo petrol with 177bhp, which is capable of 132mph and has CO2 emissions rated at 164g/km. An even more powerful VXR hot hatch will be introduced later – first details are expected before the end of the year.

The diesel, meanwhile, is a new 163bhp 2.0-litre unit – again with start-stop and a six-speed gearbox as standard. This is capable of 0-62mph in 8.9 seconds and 130mph, with 129g/km CO2 and 57.6mpg. It has a theoretical range of over 700 miles per tankful as a result.

Two specification levels will be offered at launch: Sport and SRi.

SRi is available from £19,945, and adds tinted glass, trip computer, leather-trimmed steering wheel and front fog lamps. Optional extras include adaptive bi-xenon lighting and new Morello Red premium leather trim with six-way adjustable front seats.

The most expensive model in the range is the SRi diesel, priced at £22,430. All Astra GTCs come with a 100,000-mile ‘Lifetime’ warranty – but only 12 months’ breakdown cover.

The new Vauxhall Astra GTC makes its public debut at the Goodwood Festival of Speed at the beginning of July. It’s available to order from Vauxhall dealers now.
