BMW i3 qualifies for both green and white HOV stickers in California

BMW buyers tend to have enough cash on hand to be buffered from the concept of "sticker shock," but the term may take on a different meaning when it comes to the German automaker's i3 plug-in vehicle and its classification by California clean-air regulators. The first i3 EVs are set to be sold in May, and some are questioning if the new car will be eligible for the state's white stickers or green High-Occupancy Vehicle lane stickers, both of which allow for solo-occupancy in HOV lanes. California gives out white stickers to some types of battery-electric vehicles, compressed natural gas (CNG) vehicles and hydrogen fuel-cell vehicles, and there's currently no limit on the number that can be given out. The green stickers, which are applied to other battery electrics as well as some plug-in hybrids, are limited (there are currently about 15,000 left) and will likely run out within the next year or two. The i3's status is uncertain because of it has an optional gas-powered range-extender. Jacob Harb, head of electric vehicle operations and strategy for BMW, told AutoblogGreen that it's not all that complicated. The pure electric version of the i3 will get the white sticker, the REx version will get the green sticker. He also said that both will qualify for the $2,500 state incentive in California and the $7,500 federal tax credit available in all 50 states (For what it's worth, Green Car Reports says the REx version will only get $1,500 from California).

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.

Corvette gets slidey with Britain's best performance cars

Autocar wants to find Britain's best driver's car, and it's challenging a murderers' row of some of the world's best performance vehicles to find out, including the latest Chevrolet Corvette Stingray. All of them were therefore assembled at the Castle Combe Circuit to find a winner.
If it wants to take the crown from this pack of mostly European competitors, the 'Vette has to beat some steep competition. Its challengers include monsters like the Ferrari 458 Speciale, Ariel Atom 3.5R and Jaguar F-Type Coupe. As a further hurdle for the winner to clear, Autocar also has last year's champ among the fighters - the Porsche 911 GT3.
Even if you're not at all interested in the C7, there's still something here for practically any fan of fast cars. The competitors include relative oddities among the pack like the Renault Mégane RS Trophy and Alfa Romeo 4C. Plus, Autocar has some well-positioned microphones that let you hear the Atom wailing like a banshee and the roar of the 458 Speciale. Check out the video to see which one of these all-stars takes home the award this year.
