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.

2015 BMW M4 Convertible is here to put wind in your sails

Each generation of the BMW M3 has included a convertible model. Even the distant E30, the patriarch of the M3 line, had an ultra-rare (only 787 were built) droptop model. The convertible became more common on the successive generations, with the hardtop-convertible E93 being the most recent. Considering this history, there seemed very little doubt that as the M3 became the M4, a convertible would be in the cards. Now, the new droptop has arrived.
Set for its global debut at the 2014 New York Auto Show, the 2015 BMW M4 Convertible features, like its forbearers, everything that's great about the hardtop variant while adding an unlimited amount of head room. That means the same 3.0-liter, 425-horsepower, 406-pound-foot, twin-turbocharged straight six sits under its domed hood, while either a six-speed stick or a seven-speed M dual-clutch transmission dispatches power to the fat rear tires.
As for specific differences between the hardtop and the new convertible, obviously, the droptop is heavier. A lot heavier. Where an M4 with a six-speed manual tips the scales at 3,530 pounds, the M4 Convertible weighs in at 4,055 pounds. Believe it or not, BMW has actually trimmed 90 pounds from the last-generation M3 convertible, code-named E93. This marginal weight reduction from the third-generation convertible to the fourth is barely half of the 174 pounds BMW was able to subtract when transitioning from M3 Coupe to M4 Coupe.

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.
