Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.

Italian coachbuilder wraps a modern-day Citroen van in a retro skin

Italian coachbuilder Caselani resurrected an obscure, often-forgotten model from Citroen's past to offer van buyers an additional retro-styled option. Called Type HG, it's based on the current-generation Citroen Jumpy. One of the French carmaker's best-known vintage vans is the Type H, which was built with only minor changes from 1947 to 1981. It's aged into a sought-after classic that's popular as a food truck and as a camper from Paris to Sydney. Few realize Citroen planned to release a smaller model named Type G which looked almost exactly like the H but used an air-cooled flat-twin engine shared with the 2CV. Several prototypes were made, but the project was canned in favor of the 2CV-based, nine-horsepower AU van released in 1951. It's this little-known prototype that only exists in Citroen's official heritage collection and in the minds of the most indoctrinated French car enthusiasts that Caselani chose to bring into the 21st century. And, because the Type G (shown below) was a shrunken copy of the Type H from a design standpoint, making a body kit that fits the Citroen Jumpy was relatively simple. Caselani liberally borrowed styling cues from its modern version of the Type H, which is based on the larger Citroen Jumper sold as the Ram ProMaster in the United States. It adds a new-look front end with a vertical grille, chromed chevrons, and round headlights positioned as far out of the body as regulations permit, corrugated body panels, and a redesigned rear end. Whitewall tires are optionally available. Caselani offers the Type HG as a passenger van, a crew-cab van, and a panel van. Pricing starts at 29,400 euros before taxes are factored in, a sum that represents about $35,000 and that corresponds to a short-wheelbase panel model powered by a 100-horsepower, four-cylinder turbodiesel engine. Alternatively, motorists who already own a Jumpy can purchase the transformation kit on its own for 14,800 euros (about $17,500). For added peace of mind, Caselani pointed out the conversion was created with Citroen's input, and the brand authorized the kit. We know what you're thinking: what on earth is a Jumpy? Glad you asked! It's a van positioned in the middle of Citroen's commercial range. It slots between the Berlingo, which competes in the same segment as the Ford Transit Connect, and the Jumper, which is marketed as an alternative to the Ford Transit.

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.
