Named in honour of Jaguar's seven victories at the 24 Hours of LeMans endurance races, the Jaguar Project 7 made a public debut by tearing up the Goodwood Festival of Speed's track in 2013. Two years later, the concept car has become a production car, with only 250 units of the F-Type Project 7 to be delivered worldwide, including seven to Canada, at a price of $188,000. "This was a group of petrol heads doing something that we thought was fun," Jaguar design director Wayne Burgess says about the F-Type-based performance car, which features a more powerful engine than the top F-Type R, plus body and styling cues from the 1955-1957 D-Type LeMans victors. But there's more to such track-inspired models for the street than just creating fun play things for designers and owners alike. Profit and technological advancement are the main drivers for these upscale but limited production vehicles, says Stephanie Brinley, auto analyst for the Americas for IHS Automotive. "These brands need to continually hone their edge and deliver technology and performance improvements," said Brinley in an email this week. Powertrain enhancements, lighter building materials, and aerodynamics are all key to making a car faster, she said, on the track or accelerating onto a highway onramp. "Standing still is not an option." This type of track-inspired passion is generating a number of new low-volume, high-performance vehicles for the street. Porsche unveiled its 911 GT3 RS model at the Geneva auto show in early March, a show which also saw the debuts of the lighter and faster 2016 McLaren 675LT and 2016 Lamborghini Aventador LP750-4 SuperVeloce. The track-ready Ferrari 458 Speciale debuted for 2014, and hitting dealerships this spring in Canada is the new-for-2015 Chevrolet Corvette Z06, a version of the already fast Corvette Stingray. Plus there's the almost-direct-copy of a LeMans legend in the Ford GT, to be built by Toronto-area engineering and race shop Multimatic starting in late 2016. It's a similar go-fast technology plus track-heavy strategy employed by many of these latest performance vehicles, each with slightly different motorsport or flavours.
