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-AMG GT pressed into service as DTM safety car

DTM is one of the most competitive, fast-paced touring car series in the world. So to set the pace, the marshals need a pretty fast car as well. And that's just what they got with the new Mercedes-AMG GT pictured here. Marking its debut at the Lausitzring speedway this weekend, the AMG GT S safety car is based closely on the road-going model, but like the version that's already in use in Formula One, it's been modified for safety-car duty. That means a low-profile light bar mounted to a carbon-fiber air scoop on the roof – both tested in a wind tunnel – as well as the front splitter and rear wing from the optional Aerodynamics package, and the optional upgraded rolling stock. Inside it's got racing buckets, six-point harnesses, a flat-bottom steering wheel, and special radio equipment. Otherwise it's essentially the same as the road-going model, right down to the 4.0-liter twin-turbo V8 and seven-speed dual clutch transmission. After all, with 510 horsepower on tap, it ought to be able to stay out ahead of the 490-hp touring cars currently competing in DTM. The new safety car replaces the C63 AMG Black Series coupe that Mercedes previously contributed to the effort, and will alternate with the vehicles furnished by rivals Audi and BMW from race to race.

A new Safety Car celebrates its DTM premiere: at the second DTM race at the EuroSpeedway Lausitz (29 to 31 May 2015), the Mercedes-AMG GT S is set to be deployed for the very first time. The new sports car will help to ensure maximum safety on the race track in the world's most popular touring car series. In technical terms, the 375 kW (510 hp) eight-cylinder sports car is for the most part the same as the series production vehicle – just like its counterpart from the FIA Formula 1 World Championship™, the Official Safety Car. In its road-going guise the Mercedes-AMG GT S has turned heads since its market launch in March 2015 and now the sports car is also taking to the DTM stage. The new season of the German Touring Car Masters (DTM) got under way during the first weekend of May in Hockenheim. The second DTM race taking place at the EuroSpeedway Lausitz at the end of May will see the Mercedes-AMG GT S make its first appearance as the official Safety Car.

2016 Mercedes-Benz C350e Plug-In Hybrid casts a green light in Geneva

Mercedes revealed another plug-in hybrid model, the C350e, at the Geneva Motor Show. Based on the company's scalable hybrid platform, the C350e offers 19 miles of electric range, and the total system makes 279 horsepower and 443 pound-feet of torque. It's part of the company's goal to bring 10 new plug-in models to the market by 2017 around the world. The hybrid system teams an electric motor with a turbocharged four-cylinder engine with a seven-speed gearbox. The C350e also has regenerative braking and can be driven in four modes ranging from Eco to Sport Plus. The lithium-ion battery pack can be charged in 1 hour, 45 seconds, and it has a total capacity of 6.2 kilowatt-hours. The C350e has an Airmatic suspension, an interior climate control system that can be controlled via the internet and offers Mercedes' suite of driver-assist technologies. Mercedes will sell the model as a sedan and a wagon in some markets. The new Mercedes-Benz C 350 e: Efficiency, dynamism and comfort – the best of three worlds The new Mercedes-Benz C 350 e: Efficiency, dynamism and comfort – the best of three worlds Following its premiere in the S-Class, Mercedes-Benz is now offering its most advanced hybrid technology yet in the C-Class and, for the first time, also in an Estate model. The dynamism and efficiency of the C 350 e make it a convincing proposition in both its Saloon and its Estate guise. With a range of 31 kilometres in purely electric mode, local emission-free driving is now a reality. Its four-cylinder petrol engine, in conjunction with a powerful electric motor, gives it a total system output of 205 kW (279 hp) and torque of 600 Nm. The new C 350 e thus delivers the performance of a sports car and yet offers certified consumption figures of just 2.1 litres of fuel per 100 kilometres both as a Saloon and as an Estate. This corresponds to CO2 emissions of 48 grams (49 grams for the Estate) per kilometre. Both models are also equipped as standard with AIRMATIC air suspension plus a Pre-Entry Climate Control system that can be controlled via the internet, adding up to a truly exceptional level of driving and climate comfort. Prof Dr Thomas Weber, Member of the Board of Management of Daimler AG and responsible for Group Research and Mercedes-Benz Cars Development: "The PLUG-IN HYBRID is an investment in the future of Mercedes-Benz and we believe it will become established as the successful technology for maximum efficiency coupled with powerful dynamic performance.
