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.

10 best new car deals in late September 2021

New car sales were drastically affected in 2020 due to the ongoing coronavirus pandemic, but things started to show signs of recovery toward the end of the year before really coming on strong in the early months of 2021. Now there's an ongoing shortage of microchips causing a great deal of pricing fluctuation and a limited supply of certain vehicles. That doesn't mean there aren't still great deals on new cars, though. Using data provided by TrueCar, we’ve compiled a list of some of the best automotive deals for September 2021. WeÂ’ve noted the original MSRP, the average transaction price, and the total savings in both dollars and as a percentage of the original sticker price. Basically, weÂ’ve done all the hard work for you! So now, all you need to do is compare deals, go on a few test drives, and maybe drive away in a great car (and an even better bargain).

Forget about greenlighting it, BMW is already testing the M2

One week ago, we reported, with some skepticism, that BMW had greenlit a car we've been waiting for since the 1 Series M Coupe was discontinued - the M2. Now, we have the first images of that new hotshot underoing testing in Germany.
What's our reasoning here? After all, this just looks like an M235i. Well, that camo is disguising swollen fenders designed to conceal wider tires. Now, these aren't production changes, and it's very likely that the eventual M2's fenders will look quite a bit different. According to our spy, the front fenders have been borrowed from the M235i Racing, while the rears are from an unknown source.
Our spies are also quick to point out a few other high-performance items on this mule. The cross-drilled brakes and blue M calipers are one such item, although we aren't sure how much they differ from the optional stoppers on the production M235i. The black wheels are borrowed from the M3 and M4, and are shod in what look like a sticky set of Michelin tires.
