The low-slung, rear-drive GT won critical acclaim for its sporty proportions, flowing surface design and unfussy interior, but its rear-drive layout has posed problems for Vauxhall engineers searching for a suitable production platform.
“We’re still looking at it, but for production we have a very busy next few years and making a small coupé a priority will be difficult," said Vauxhall managing director Rory Harvey at the Goodwood Festival of Speed.
According to Vauxhall design chief Mark Adams, the GT’s flowing body and detailing, such as the front grille, are most likely to “inform other production models”.
Vauxhall’s next new model is the Insignia, due to be unveiled at the Geneva show in 2017, and likely to first be revealed late this year.
At Geneva, a source revealed that a production GT could be engineered around the rear-diff and suspension from the all-wheel drive Mokka, but Vauxhall would also have to find a compact rear-drive gearbox to complete the driveline.
Despite these production difficulties, Vauxhall is using the GT as a design demonstrator, and at Goodwood teamed it up with two iconic concepts from the 1960s – the Vauxhall XVR and Opel Experimental.
"The 1960s are my favourite era for car design," said GM design chief Ed Welburn, "and the XVR is special. I’d say that if you showed it to some young design students even now it would create a lot of buzz."
Welburn made his last official public appearance at the Festival of Speed, ahead of retiring on July 1, and fresh from a two-week European tour in his C6 Corvette, specially flown in the from the US to attend Le Mans and Goodwood.
The XVR was designed in 1966 as the first project to come out of Vauxhall’s then-new studio in Luton, under the control of Wayne Cherry. When it opened in 1964, the Luton studio cost the princely sum of £2.25m.
