BMW M4 Coupe laps 'Ring in 7:52, bests outgoing M3

Comparing Nürburgring Nordschleife lap times is a bit of a black art, especially when looking at times officially set by manufacturers matched against other sources. Driver skill and weather conditions play a huge roll in determining a quality time. Still, it appears BMW fans have reason to celebrate because the new M4 Coupe beat the previous-generation M3 by 13 seconds in a recent test by Germany's Sport Auto magazine.
Sport Auto conducts what it calls the Supertest, where it runs performance cars around the 'Ring and the short course at Hockenheim to create its own database of comparable times. The M4 with a dual-clutch transmission, ceramic brakes and Michelin Pilot Supersport tires managed a quality 7 minutes 52 second lap around the 12.8-mile course, compared to 8:05 from the last M3, according to BimmerPost. The new coupe also beat the magazine's posted times for the Audi RS5 Coupe, which did it in 7:59, and Mercedes-Benz C63 AMG with an 8:01, but couldn't quite match the 7:44 set by a 911 Carrera S. Still, BMW must be somewhat pleased with these results of its new 425-horsepower coupe because it posted the magazine's cover and an image of the time on its official M Facebook page.
While the M4 apparently stands up to contemporaries and predecessors, new generations of the AMG and RS models are reportedly on the horizon. In other words, more tests will come.

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.

BMW is ready for our inevitable EV future  

Is "rolling lithium" a thing, yet? Because BMW is trying to make this — the opposite of " rolling coal" — happen at this year's Los Angeles Auto Show. The Bavarian vehicular group is showing five all-new electric-powered concepts or production models in L.A. These include the C-Evolution, a 99-mile range scooter from BMW Motorcycles; the 150-mile range, two-door hardtop Electric Concept from Mini; and three vehicles from its advanced i sub-brand: the i3S, a sportier and more potent version of the brand's electric commuter nodule; the i Vision Dynamics four-door coupe concept, featuring a sporty four-second 0-60 time and a professed 373 mile range; and the long-promised roadster version of the i8 supercar, with just two seats, a bikini top, and an enhanced power pack providing 18 miles of range. The unveiling of these vehicles in Los Angeles makes perfect sense to us. California is one of the world's largest markets for luxury automobiles. It is also America's biggest market for electric-powered vehicles. Studies show that the state's combination of fiscal incentives, trendsetting cultural positioning, legislative requirements and massive population contributed to the purchase of half of the country's EVs and hybrids this decade. "The customers for the brand are mainly on the West and East Coasts, and the California customer especially is interested in sustainability and environmental protection," said Robert Irlinger, head of BMW's advanced i sub-brand. The bigger question revolves around BMW's larger EV strategy. Given the current global regulatory environment, with its rightful pressures on increasing efficiency and decreasing emissions to help soothe our warming planet and save all life on it, luxury automakers seem to be making a push toward developing a range of battery-powered vehicles to be available around or after the start of the next decade. It seems BMW, with its varied subsidiaries — from lightweight scooters to ultra-luxury barges — is uniquely poised to provide an array of such vehicles. "In the first stage of i back in 2013, we brought what you could call 'bookmark' cars to the market — the i3 commuter and i8 sports car — to show the range of what an electric vehicle could be," said Irlinger. "Now, we are seeing growing interest from customers to bring electrification to the heart of the brand, even to a sport sedan like our i Vision Dynamics four-door coupe.
