BMW eyes Z4 replacement before 2020

As BMW has been busy building four-door versions of two-door versions of four-door cars, less useful crossovers and front-drive minivans, you could be forgiven for thinking it had given up on its aging Z4 roadster. But that, we're pleased to report, isn't the case. According to Automotive News, BMW is hoping to release the next-generation Z4 (if that's what it ends up being called) before the close of this decade. The news outlet spoke to the company's chief engineer, Klaus Frohlich, at the 2015 Geneva Motor Show, who indicated that BMW may split costs on the new car with Toyota, as part of the partnership between the two automakers. This partnership is integral to the next-gen Z4, largely because of the declining importance of the roadster segment, Herr Frohlich indicated. "If you look at the volume... we have to realize that these segments are shrinking," Frohlich told AN. According to the publication, sales of the Z4, which hit the market in its current form back in 2009, dropped 11 percent in Europe and 13 percent in North America. The car also is less attractive to customers in China for a number of reasons. "[Chinese customers] are not interested in roadsters," Frohlich explained. That's because privacy is a high priority for drivers in China, AN said. On top of that, open-roof cars expose their customers to China's notorious air pollution, which drivers are understandably keen to avoid. Related Video:

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.

The 2017 Alpina B7 xDrive isn't as cool as the BMW M760i

Steve Ewing is good people, but when it comes to big BMWs, he talks nonsense. He argues, incorrectly, that the new Alpina B7 is somehow cooler than the new M760i. Here's why he's wrong. No surprise, but the bulk of the pro-M760i argument comes from under the hood. Yes, both cars produce 600 horsepower and 590 pound-feet of torque, but it's where the power comes from that really matters. The M760i's power is just much more accessible, with peak torque coming in at just 1,500 rpm, while the Alpina makes owners wait until 3,000 rpm for max twist (a fact Ewing glosses over). The V12 also offers up all 600 horsepower at 5,500 rpm, 250 rpm earlier. Sure, the Alpina is 0.3 seconds faster to 60 miles per hour – it does the deed in 3.6 seconds to the M760's 3.9 seconds – but it relies on a tweaked transmission setup to do it. Not only that, but big automakers like BMW are usually quite conservative about performance figures, so it's still a bit early to hand a medal to the aftermarket. Here's the other thing about the engines – Nigel Tufnel would prefer the M760i. See, the Alpina has a 4.4-liter, twin-turbo V8, but the M760i has a 6.6-liter, twin-turbo V12. To paraphrase Tufnel, "This one has a V12." We rest our case. Other changes between the two cars are largely in the eye of the beholder – we can talk about the transmission, suspension, and xDrive changes until we're blue in the face, but we simply don't have enough information about the two setups to make substantive arguments – some people might prefer the subtler styling of the M760i. We're not going to blame anyone for liking the more aggressive look of the Alpina, with its big, quad-tipped exhaust, meaty front splitter, or aggressive side sills. And those 21-inch Alpina wheels? Easily the coolest styling detail. You can get a closer look at them, and the Alpina's other changes, in our live gallery from the floor of the Geneva Motor Show.
