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.

Top Gear drag races the BMW i8 and M4 to decide the future

The BMW M4 and i8 represent two every different expressions of the performance car. The M4 relies on its turbocharged six-cylinder combustion engine to spin the rear wheels. Conversely, the i8 packs a turbo three-cylinder and electric motors for its cutting-edge all-wheel drive system. Top Gear is the latest publication to put the pair together to find out which ethos is quicker. We saw Germany's Auto Bild hold a similar race last year, and the i8 scored a clear victory there. We don't want to spoil the winner of Top Gear's attempt, but we can tease that this sprint ends in a photo finish. Pick your favorite, and then watch the video to see which performance coupe takes the checkered flag. Related Video:

Pininfarina Battista hypercar's output specified at 1,873 horsepower

Even in a galaxy far, far away, the Pininfarina Battista would stand out. After a delay of about three years, the official specifications of the all-electric hypercar have been revealed: Full power is rated at 1,873 horsepower, outputting 1,697 foot-pounds of torque. Sixty-two miles per hour arrives in 1.86 seconds, with 124 mph coming in 4.75 seconds. 217 mph is the estimated top speed. (The Rimac Nevera recently hit 258.) The 120kWh battery pack should enable a range of about 280 miles from a single charge. A pair of electric motors are mounted to each axle, each motor powering a specific wheel and giving the Battista full torque vectoring capability. Pricing — and this is one of those cars that, if one has to ask, just move on — is about $2.2 million, which places it in the territory of the Bugatti Chiron. For those customers considering an upsell, a limited “anniversario” edition will comprise five of the expected 150-unit build run. It differs from the standard version by some cosmetic alterations, which lifts the price by some $70,000-plus. 0r you could buy a BMW M3 as a chase car. The two-seater Battista is named for Battista “Pinin” Farina, who founded Carrozzeria Pininfarina in 1930. A lot of its battery, carbon-fiber chassis and motor components come from Rimac, the nascent Croatian electric supercar maker that recently paired with Porsche to take over Bugatti.  Many more details about the carÂ’s development, several photos and our driving impressions can be found in this Autoblog post from August.   Auto News By the Numbers Green BMW Bugatti Green Automakers Green Driving Coupe Performance Supercars Pininfarina Battista
