give me the moonlight

Walk into any team’s base and the immediate impression is of a hive of activity. Workers intensely crafting esoteric parts for a racing gem: attention to detail, concentration, using every tool they have to strive for the exceptional. But teams are composed of individuals, each with their own life and aspirations. And, being human, they are sometimes not averse to using the facilities at work for private projects. I have seen some interesting examples of this in my teams over the years. Some produced works of art on the side. One of our fabricators at Fittipaldi, Pip, who is no longer with us, could do anything with metal, be it steel, ally or titanium. The team stores, with an assortment of metal for the F1 build, could be depended on to…

the word on the street

Recently I’ve driven five very different road cars from equally different eras, all but one being a privilege, really. The two most extreme are my 1961 Mk 2 Jaguar 3.8 versus a contemporary Audi RS3. This experience has served to remind me of the progress in automotive engineering and driver experience that has happened in the intervening half-century or so, also the level of influence that motor racing has played in their development. Of the two cars, the RS3 is clearly far and away the superior vehicle, as it should be. If it wasn’t, the motor industry would have been wasting time for six decades. It has stunning acceleration, a superb seamless automatic transmission, great brakes and cornering ability. If I had to criticise, it would be that the 400+ bhp…

griller warfare

With new regulations due in 2022 that will effectively force manufacturers to build new GT3 cars (see last month’s issue, V30N2), this year could be the last that competing brands have the chance to introduce new versions of existing models. Mercedes has grabbed this opportunity with both hands and introduced its update to the AMG GT3 that was first run in 2016, and has since won multiple driver and manufacturer titles. This new version was set to make its debut at the Daytona 24 hours in late January. Since the introduction of the outgoing model, the face of GT3 racing has changed dramatically and Mercedes needed to step up to meet new and rather novel challenges. Mid-engine cars from Audi and Lamborghini, which share a base platform, in particular have set their cars…

the rush of racing

The true innovation would come in realising this design in a ready to race package that costs just $28,900 The Rush SR-1 is the brainchild of mechanical engineer David Hosie, who originally harks from Scotland. Having completed his engineering degree in Aberdeen the oil and gas industry was the natural place for him to hone his skills, and this explains why he now resides in Houston. Hosie serves on the board of directors of an oil and gas company but, parallel to his career in this industry he’s been heavily involved in racing for quite some time. ‘I’ve always been in motorsport for one reason or another, be it karting to running a five-car Formula Renault team [known as Fran Am 2000] for three years here in the US,’ says Hosie.

setting the pace

‘We have worked tirelessly to get the most out of this road car powertrain to make it suitable for the racing world’ There are many examples of manufacturers transforming road cars into racers, but one of the most impressive approaches to this must be that which Jaguar has taken for the world’s first all-electric international race series for production models; the Jaguar I-PACE eTrophy. Now in its second season, this is the official support series to Formula E, where drivers battle it out across 10 rounds of racing with the winner of the Pro category claiming a prize worth £500,000. What is most interesting about this racecar, though, is the fact that Jaguar has not only managed to combat the technical challenges of upgrading its first all-electric road car to suit racing,…
