The 2016 Spanish Grand Prix flipped all the scripts

The Monaco Formula 1 Grand Prix circuit and the Hungaroring fly the flag for processional races, yet Spain's Circuit de Catalunya is arguably as bad. Before this weekend, the pole-sitter won the race 19 times out of the last 25 years. The front row of the grid produced 23 winners in the past 25 years. The racing gods edited that script this year, when a first-lap crash and two mid-race strategy changes kept things open until the end of the 66-lap race. It started when Mercedes-AMG Petronas teammates Nico Rosberg and Lewis Hamilton took each other out on Lap 1. After Rosberg passed pole-sitter Hamilton into Turn 1, Rosberg's car slowed through Turn 3, somehow in the wrong mode. Hamilton closed in on Rosberg so quickly that once the Brit ducked inside for the pass, he couldn't back out. Rosberg, however, closed the door so suddenly that Hamilton had no choice but to drive onto the grass. When Hamilton spun, he collected Rosberg and both Mercedes' ended up in the gravel trap. The stewards deemed it a racing incident. The crash put Red Bull teammates Daniel Ricciardo and Max Verstappen in the lead, followed by Toro Rosso driver Carlos Sainz and the Ferrari duo of Sebastian Vettel and Kimi Raikkonen. Both Ferraris cleared Sainz by Lap 10, leaving 56 laps for them to haul in the Red Bulls. Ferrari loosely followed Red Bull's pit strategies. Ricciardo pitted on Laps 11 and 28, Vettel pitted on Laps 15 and 37. Verstappen pitted on Laps 12 and 35, Raikkonen pitted on Laps 13 and 36. Pirelli predicted a three-stop race as the fastest and that the medium tire could only go about 23 laps. Verstappen and Raikkonen didn't get those memos. So while Ricciardo and Vettel came in for third stops the Dutchman and the Finn stayed out, with Verstappen ahead of Raikkonen at the front of the race as of Lap 43. That's when Verstappen – 18 years and 227 days old – proved how good a driver he is, lapping perfectly as second-place Raikkonen closed the gap to a little more than half a second. The Finn still couldn't get past the Dutchman down the pit straight even with the help of DRS, nor under braking at the only real passing opportunity into Turn 1. At the end of Lap 66 Verstappen crossed the line ahead of Raikkonen, a victorious end to Verstappen's first race weekend after being promoted to Red Bull. Further back, Vettel and Ricciardo fought for scraps, the German staying ahead to finish third.

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.

Mercedes-Benz C-Class scores well in TUV lifecycle analysis

Mercedes-Benz drivers and treehuggers don't always go hand in hand, but, like a lot of other companies, the German automaker is looking to boost its green cred. This time, it's all about the car's lifecycle carbon footprint. The Daimler AG unit is using its new C-Class sedan as an example of how it's making progress in that department. Mercedes-Benz, citing the inspection authority TUV Sud, says the 2015 C-Class has a 10-percent lower lifecycle carbon footprint than its 2014 predecessor, based on driving about 125,000 miles over the life of the car. About 95 percent of the car (by weight) is recyclable, slightly higher than the average for most vehicles, and the model has upped its amount of recyclable materials up by 23 percent and increased its use of "natural materials" by 55 percent. Better aerodynamics also helps things out on the fuel-economy front, Benz says. Taking a longer view, the 2015 C-Class's carbon footprint is 28 percent better than the 2007 version that launched the vehicle line. The 2015 C-Class hasn't received a fuel-economy rating from the US Environmental Protection Agency, which tagged the 2014 C350 with a combined fuel-efficiency rating of 24 miles per gallon from its 3.5-liter 6-cylinder engine.

TUV Environmental Certificate: The new C-Class makes its mark with an exemplary life cycle assessment Stuttgart, Mar 28, 2014 The C-Class sets efficiency benchmarks for its class, helped by an intelligent lightweight concept, excellent aerodynamics and new, frugal engines. The neutral inspectors from the TUV Sud technical inspection authority have confirmed the high level of environmental compatibility of the new Mercedes-Benz C-Class. Besides a sensuous, clean-cut design, a top-class interior and a host of technical innovations, the premium saloon also boasts an exemplary life cycle assessment, which is why it has been awarded the Environmental Certificate in accordance with the ISO 14062 standard. Professor Dr. Herbert Kohler, Chief Environmental Officer at Daimler AG: "Our engineers have pulled out all the stops in an effort to lower fuel consumption while at the same time further accentuating the car's sporty character. By employing an intelligent lightweight design with a high proportion of aluminium, for example, it has been possible to make the new C-Class up to 100 kilograms lighter than its predecessor.
