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.

Renault's ambitious EV strategy relies on historic nameplates

PARIS — Renault unveiled a more ambitious strategy for electric vehicles (EVs) on Wednesday, betting on new, affordable versions of its iconic small cars of the past to catch up with Volkswagen in the fast-growing sector. The French carmaker's Chief Executive Luca de Meo said it would launch 10 new EVs by 2025 and that all-electric vehicles would account for up to 90% of its models by 2030, dropping its reliance on hybrids to hit the target under a previous plan. Renault is betting that an electric version of its classic Renault 5 compact car, which was discontinued in the 1990s, will capture the imagination of today's drivers when it goes on sale in the first half of 2024. At a live-streamed presentation on Wednesday, the company also offered a fleeting glimpse of its new electric "4ever." model. Two sources close to the company said it was a revival of the Renault 4 hatchback which went out of production last century. "Today is an historic acceleration of Renault Group's EV strategy," de Meo said in a statement. De Meo said that new, purpose-built electric car platforms and a cluster of production sites in northern France would allow Renault to deliver EVs at a lower cost. The first of its new EVs will be the MeganE hatchback which is due to go on sale in the first half of 2022. This content is hosted by a third party.

By 2030, Renault and its alliance partners, Nissan and Mitsubishi, will be producing 1 million EVs globally a year, up from the 200,000 they made in 2020, the French carmaker said. Tesla, the world's most valuable carmaker, is already close to hitting that target, with sales of between 840,000 and 1 million EVs projected for this year. Shrinking share Renault's Zoe model, the biggest-selling battery electric car in its segment in Europe for years, is losing ground to models such as Volkswagen's ID.3 compact electric car. Figures from database EV-Volumes.com showed Volkswagen's share of the EV market in Europe soared to 25% last year from 14% in 2019, overtaking the Renault-Nissan-Mitsubishi alliance, whose share shrank to 19% from 23% in 2019. In the first quarter of 2021, Renault's share fell further to 15%, tying with Tesla for third place behind Volkswagen on 21% and Stellantis on 17%, EV-Volumes.com data showed.

Williams developing hybrid system for next Nissan GT-R?

Back in June, Nissan announced a new partnership with Williams that would see the Formula One team's applied sciences division help develop a new line of Nismo performance models. It's not the only agreement Renault-Nissan has signed with an F1 team: Infiniti is the title sponsor for Red Bull and Renault powers four teams on the grid. It's also just the latest client Williams has signed a deal with to apply the lessons it has gleaned on the F1 circuit to other racing and sportscars. But now we've got some more info on how Williams and Nismo intend to collaborate on the next-generation GT-R.
According to Australia's Carsales, Williams Advanced Engineering is developing the hybrid powertrain that will boost the next iteration of the supercar-slayer known as Godzilla. Which may seem strange considering that the Renault-Nissan Alliance has plenty of experience with electric propulsion on its own, but then Williams has proven itself something of a leader in the field of performance hybrid powertrains: it supplies them to Porsche and Audi for their Le Mans racecars, and to Jaguar for the C-X75 concept.
Whether Williams and Nismo will settle on a flywheel-based energy recovery system or a more conventional battery-powered system remains to be seen, but brakeforce regeneration likely won't be the only element that Williams will develop for the next GT-R. Expect its expertise in aerodynamics and composites to come to bear as well, which can only mean good things for the replacement for a sportscar that's already one of the most capable on the road.
