Nissan VP suggests next Z will offer multiple engines

Roel de Vries, the corporate vice president and global head of marketing and brand strategy for Nissan, told Australia's CarAdvice that as far as he's concerned, any engine in the 370Z "[needs] to deliver on what the car stands for and if the 370Z stands for real performance and real driving I think it doesn't need a V6 to do that." At first read, it could look like de Vries is softening us up for a next-generation Z that doesn't come with a V6, a move that would disappoint a lot of the coupe's fans. Or, what if de Vries was actually getting us ready for a Z with multiple engine options, instead of only a V6, in order to expand its global appeal? That appeared to be the gist of his comments, the exec saying that they couldn't sell a V6-engined Z in Europe, but even if they offer a four-cylinder there, the V6 could live on because, "why should we give it up?" With the coupe's current name a factor of the 3.7-liter displacement of it's V6, though, what is the future for a car with several engine options? Said de Vries, "We [will] definitely keep the Z name, but when we did 350 to 370 it was because of the capacity, but who says the next-generation doesn't have three engines and its not just called Z?" This kind of talk has been going on all year, the real question being how many engines will the car get and what's the endgame. At the beginning of the year, ex product chief Andy Palmer said the car codenamed Z35 would use a "downsized four-cylinder turbocharged engine." In August, Motor Trend reported that the next Z would offer "a mixture of smaller but powerful engines," including a hybrid, but that a V6 would remain the headliner. Two weeks later, MT said that Nissan wanted to transition customers from the naturally aspirated V6 to a turbocharged four-cylinder with the same power, eventually, but would begin with both on the menu. Parallel to that are Shiro Nakamura's out-loud musings about how to merge the next Z and the IDx concepts into "a more affordable, more approachable sports car." The answers, whatever they are, will be a big deal for the brand.

2014 Nissan Juke Nismo RS amps up the funky crossover

Nissan unveiled an even hotter version of the hotter Juke Nismo at the Los Angeles Auto Show - the Juke Nismo RS, a 215-horsepower crossover that may be the most hardcore model in the compact CUV segment (until we can convince Mazda to build a Mazdaspeed CX-5, that is).
The 215 hp and 210 pound-feet of torque represent bumps of 18 hp and 26 lb-ft over the standard Juke Nismo thanks to a revised ECU, a new exhaust with a larger diameter tube, and stronger connecting rods. This amped-up engine can be mated to the owner's choice of a six-speed manual, which takes advantage of a stronger clutch cover and dual-mass flywheel, or an Xtronic continuously variable transmission (although the CVT model loses four horsepower and all of the extra torque that the Nismo RS enjoys).
"We expect drivers to feel a noticeable increase in acceleration - especially the manual transmission model - in the RS versus the regular Juke Nismo. It also holds peak torque longer. Combined with the Helical Limited-Slip Differential, which helps reduce torque steer, the sense of driving excitement is unmatched in the Juke lineup," said Pierre Loing, Nissan's vice president of product and advanced planning and strategy.

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.
