Buick Enspire EV crossover concept claims 370 miles of range

For the Beijing Auto Show, Buick is showing yet another crossover, this one in concept form. It's called the Buick Enspire, and unlike the rest of the brand's crossovers, this one is all electric. It's more than just a repurposed Bolt EV, too. Instead of the Bolt's 150 kW and 200-horsepower motor, the Buick has a 410 kW motor, which equates to 550 horsepower. Buick claims the motor will get the crossover to 60 mph in just 4 seconds. The Enspire isn't all about performance, though. It would also have a very healthy claimed range of 370 miles, topping that of the longest-range Tesla. Fast charging is supported, with Buick saying it can recover 80 percent of its charge within 40 minutes, though the company doesn't say how potent the charger used for that number is. It also apparently has support for wireless charging. This Enspire concept is rather pleasant looking, too. It has smooth, elegant curves draped on a body with a very wide, aggressive stance. The grille is an interesting evolution of Buick's current design, exaggerating the current crossbar into large wings that spread into the lights, and trading the vertical slats of the main grille for a solid illuminated insert. The rear taillights are also distinctive in how they comprise one long, slender line that form a pseudo spoiler in the rear hatch. The interior is plenty swoopy, too, with a number of futuristic touches. It has an OLED touchscreen for infotainment, and the windshield features augmented reality capabilities displaying road information and navigation routes. Luxury touches include real wood arm rests and center console. Whether we'll see a production Buick with the capabilities of the Enspire is anyone's guess. Surely to have that level of power and range would make it immensely expensive, similar to or surpassing the Tesla Model S and the Jaguar I-Pace. That would be rarefied air for Buick. But we wouldn't be surprised to see either an all-new crossover, or a redesigned current model, sporting the designs seen on this concept. And many of the cues will likely spill over to other Buick products. And while the performance seen in this concept might not reach production, we also wouldn't rule out an electric Buick of some sort, probably a crossover in the near future. General Motors has made it very clear it's going to push electric vehicle development, and a Buick crossover would be a good choice for a few reasons.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

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.
