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.

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.

2016 Malaysian Grand Prix recap: Surprises and missed opportunities

Mercedes-AMG Petronas pilot Lewis Hamilton drove so well in the run-up to the Malaysian Grand Prix that he said before the race, "Honestly, I don't feel anything is going to stop us." On Sunday, the Sepang race showed what it thought of plans and predictions. Heading into the right-hand Turn 1, Sebastian Vettel practically recreated the dust-up at the Belgian Grand Prix three races ago. When Mercedes' Nico Rosberg swept across from the outside line toward the apex, Red Bull's Max Verstappen had to jink right to avoid, touching Vettel's Ferrari on the inside. Vettel speared straight on and hit Rosberg. Vettel's left front suspension broke, ending his race. Rosberg spun and got moving again, but at the back of the pack. That appeared to put Hamilton on a clear run to the checkered flag. His car looked perfect, his pace was perfect, he easily kept Red Bull's Daniel Ricciardo and Verstappen behind. A result that would have seen Hamilton retake control of the Driver's Championship – at Petronas' home race – got crushed on Lap 41 when Hamilton's engine blew down the main straight. That put Ricciardo in the lead, followed closely by his teammate. Just two laps before Hamilton's exit, Ricciardo and Verstappen had battled for second place with some of the best driving we've seen all season. Ricciardo drove as if exorcising the demons of missed opportunities earlier in the year, keeping the young Dutchman behind. The two Red Bulls took the flag fifteen laps later in that order, clocking the first one-two finish for a team other than Mercedes since 2014. It's Red Bull's first one-two since Brazil 2013, when Vettel and Mark Weber took the top steps at the last race of the V8 era. Rosberg recovered to take third in spite of a ten-second penalty for an optimistic pass on Ferrari's Kimi Raikkonen. The Finn crossed the line 12 seconds later, followed by Valtteri Bottas in the Williams and Sergio Perez in the Force India. In another Belgium repeat, Fernando Alonso drove from the back of the grid to finish seventh. Nico Hulkenberg secured eighth, Jenson Button ninth for McLaren in his 300th grand prix, and rookie Jolyon Palmer scored his first point of the season for Renault in tenth. The issue to trump all others from now until next week's Japanese Grand Prix: Lewis Hamilton's terrible luck with engines. Power unit gremlins earlier this season helped drop the Brit to 43 points behind Rosberg after the Russian Grand Prix.
