BMW Concept 90 Motorcycle debuts at Villa d'Este

The Concept 90 is one of two new vehicles BMW is showing off at the Concorso d'Eleganza Villa d'Este on the tony shores of Lake Como in Italy. This year is the 90th anniversary of BMW Motorrad and the 40th anniversary of the R 90 S (inset) - the first production motorcycle to come with a front fairing - and BMW has worked with custom bike builder Roland Sands Design to craft a homage to the Daytona Orange boxer from the Seventies.
While following the line of its forbearer, obviously the Concept 90 has been sexed and sleeked up. The bodywork is of hand-worked aluminum, the giant halogen lamp of the 1975 model (which is when Daytona Orange was introduced) has gone LED, and the front engine cover, valve covers, exhaust and wheels have been made with a contrast-cut milling process.

BMW 4 Series Gran Coupe spotted wearing minimal camo, M Sport pack

The new BMW 4 Series is essentially the coupe version of the latest 3 Series. So it would stand to reason that the four-door version of the 4 Series, in turn, would be the 3 Series - right? Well, yes and no.
Just as BMW offers both a 5 Series sedan and a four-door version of the 6 Series called the Gran Coupe, so, too, will its 4-Series family expand. So following the release of the new 4 Series Convertible, here we have the latest batch of spy shots showing the upcoming 4 Series Gran Coupe - which in turn should not be confused with the hunchbacked 3 Series Gran Turismo, which is more of a sporty wagon than a four-door coupe.
The nearly ready test vehicle pictured here is wearing only minimal camouflage to hide some last few details, but also appears to be wearing the M Sport package that will bridge the gap (at least, visually speaking) between the base models and the M4 Gran Coupe that is all but certain to follow.

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.
