Alex Zanardi talks new challenge at 24 Hours of Spa with BMW

"I have overcome greater things in my life than driving at night." When considering Alex Zanardi's tumultuous life and racing career, the notion that he might be worried about racing for the first time at night seems patently absurd the moment I pose the question. But as I've discovered previously, ask Zanardi a question and his reply - even a brief one - will offer analysis. "I'm really looking forward to it," he says, before adding: "Also, it will be much cooler." Zanardi is talking about the latest installment in his racing career - the 24 Hours of Spa - where he will race a BMW Z4 GT3 alongside fellow ex-Formula 1 driver Timo Glock and DTM driver Bruno Spengler. For the second year, Zanardi is running with ROAL Motorsport, and the team has the full weight of BMW behind it as it prepares to go up against 57 other cars on the historic Belgian circuit this weekend. I first met Zanardi last year at Brands Hatch on a hot May afternoon after his one-hour Blancpain Sprint Series race. He was exhausted and downing can after can of cola but still happy to chat to fans as he cooled off. I ask why, if that was such a tough experience, he is prepared to do it for 24 hours. "It's a good question, why would I?" he ponders aloud before quickly adding: "I am confident I am as well-equipped as I can be to face such an enormous commitment." That confidence comes from three developments that have allowed him to be the first disabled driver to race the Spa 24H. Firstly, his athleticism; since Zanardi lost both his legs in the horrific CART accident at the Lausitzring in 2001, he has drawn admiration for his subsequent achievements as a racing driver and paracyclist; the Italian won two golds and a silver at the 2012 London Paralympics in handcycling. The man is seriously fit. The next major change is inside the Z4 cockpit, where he has worked with BMW engineers to adapt the braking system without hindering his able-bodied teammates; having two others sharing the car with him is a new challenge for both Zanardi and BMW. New controls, particularly the brake pedal, were designed with impressive results. "[The engineers] made my life easier quite dramatically via ergonomics, pushing the brake pedal and the footrest where I put my prosthetic feet to the side of the space that was available. "This makes everything better for me. The ratio of the brake pedal is changed.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

Sunday Drive: Taking a gaze into the automotive crystal ball

Mankind has long been fascinated by the future. So it makes sense that this past week's top stories were all about cars, trucks, and SUVs that won't be hitting the market until the 2019 model year. And right at the top of the list is the Ram 1500. We've come to know Ram as the truck maker that styles its pickups with cues cribbed from big rigs, but that look has slowly evolved over time into something uniquely its own. The next Ram 1500 continues this trend, with a newly refined look that we can't wait to see in person. Up next is the 2019 Chevy Silverado. Pickup trucks have been, continue to be, and will remain the best-selling vehicles in America. And General Motors is a leader in the field, with two distinct offerings with which to entice buyers, one from the bread-and-butter Chevrolet brand and one wearing the slightly more upscale GMC badge. The Chevy looks to get LED lighting elements for 2019, which ought to keep the truck from looking dated when compared to the Ford F-150 and the previously mentioned Ram 1500. From there we move past pickup trucks and into SUVs and sedans. The 2019 Jeep Cherokee looks to get toned down a bit with its next refresh, and the '19 BMW 3 Series continues its slow evolutionary journey at the top of its aspirational sales pedestal. Finally, spy shots give way to official production reveals for the 2019 Audi A7 and Polestar 1. This pair of European luxury cars won't compete with one another – one is a rakish hatchback and the other a sports coupe – any further than for the eyeballs of our readers, but both proved popular enough to merit inclusion in our weekly roundup.
