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.

Jay Leno goes offroading with the legendary Ivan 'Ironman' Stewart

Jay Leno takes a step outside of his cavernous garage for this latest video for a jaunt into the desert to get a little dirty. He meets up with off-road racing legend Ivan 'Ironman' Stewart, who has multiple Baja 500 and 1000 wins in his motorsports career, to play with a Toyota Tundra in the sand.
Unfortunately, Leno doesn't get to interview Stewart too deeply about his long history in racing, but Ironman does talk a little bit about reading the trail while speeding through the desert. In lieu of a great conversation, there is a ton of high-quality footage of the Toyota bounding through the desert.
This clip feels more like a marketing effort than the usual output from Jay Leno's Garage, but it's still great to see Stewart behind the wheel sliding a truck, just like old times. The two of them even take the truck on a somewhat humorous journey at the end of the video.

2014 Toyota Corolla debuts with more power, interior space

Depending on who you ask, the best-selling car in the world is either the Ford Focus or Toyota Corolla. Not surprisingly, Toyota claims it's the Corolla. Either way, we're talking around a million individual units per year, and over 40 million over the car's lifetime on the market, so the redesign of Toyota's compact sedan is big-time news for the Japanese automaker that it needs to get right.
The Toyota Corolla was last redesigned way back in 2008, meaning the 2014 model is a long-overdue update to the C-segment sedan. Its age shows when compared to newer rivals like the Honda Civic, Chevy Cruze, Hyundai Elantra and the aforementioned Ford Focus when comparing technology features, fuel mileage and interior roominess. In an effort to solve those demerits, Toyota has added nearly four inches to the 2014 Corolla's wheelbase and will offer a new continuously variable transmission with seven simulated gear ratios.
Engine choices consist of two available 1.8-liter four-cylinder units, one with 132 horsepower and 128 pound-feet of torque, and another more efficient version that uses Toyota's new Valvematic technology to offer 140 horses and 126 lb-ft of torque. Eco and Sport modes will be selectable by the driver.
