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.

Chrysler, Nissan minivans earn 'dire' crash test results, says IIHS [w/video]

First introduced in 2012, the Insurance Institute for Highway Safety's small-overlap frontal crash test has become the bane of many auto engineers' existence. It's a particularly steep design challenge because it forces just 25 percent of a vehicle's front end to take the brunt of a 40-mile-per-hour impact. The newly released results of four family-minded minivans underscore just how difficult the crash test is: only one scored an Acceptable rating, and the other three did very poorly. The 2008-2015 Chrysler Town & Country and Dodge Grand Caravan, plus the 2011-2015 Nissan Quest, all received Poor ratings in the test, the IIHS' lowest possible score. The three of them showed significant crash intrusion into the driver's area. The dummy in the Nissan actually had to be cut out of the vehicle, with an IIHS spokesperson remarking, "the structure collapsed like a house of cards." In the Fiat Chrysler Automobile vans, the steering wheels moved out of the way, making the airbag less effective and letting the driver's head hit the dashboard. While it was not actually crashed, the agency is also giving the 2009-12 Volkswagen Routan a Poor score because it shares a structure with the FCA models. The newly released results of four minivans underscore just how difficult the small-offset crash test is. The refreshed 2015 Toyota Sienna (shown), conversely, earned an Acceptable rating and is also a Top Safety Pick+ because of its optional forward collision warning and automatic braking system. While the crash test dummy moved around during the impact more than the agency would have liked, sensors showed a low risk of injuries. The IIHS tested the Honda Odyssey last year, and it earned a Good overall score, the agency's best ranking. It's also a Top Safety Pick+ vehicle. The only member of the minivan segment left to test is the latest Kia Sedona, and the Institute is reportedly waiting a little longer for Kia to make changes to improve the model's performance. When reached for comment, Nissan spokesperson Steve Yaeger provided Autoblog with the following statement: "Nissan is committed to vehicle safety and believes that consumers should have information about crash protection so they can make educated buying decisions. Nissan is proud of the 2014 Quest's "good" rating in the IIHS front moderate overlap and side impact tests as well as a "good" head restraint rating.

Weekly Recap: Ford GT inspires guitar, foosball table, sailboat

Ford design vice president Moray Callum had just wrapped up a briefing on the interior of the Ford GT last month, but something seemed out of place. He grinned and pointed behind him, "You might be wondering why I have a boat behind me," he said mischievously. It was there because Ford set its designers on a mission to stretch and showcase their talents: design non-automotive objects inspired by the interior of the GT supercar. Callum received quite a response, too. His team produced a guitar, a foosball table (yeah bro!), a racing sailboat, a Wi-Fi speaker and some furniture. As the veteran design chief explained, "It's a really great exercise both to highlight our designers' talents, but also to really see how our design philosophy can work and how you can use it and get a common response back from a worldwide design team." Guitar View 25 Photos The objects have been on display this week at the Salone del Mobile furniture and fashion design fair in Milan, Italy, where Ford has had a presence for three years. There's also a light exhibition that apparently was inspired by the GT, as well. While this might seem a little far-fetched for the automaker, Ford said exhibitions like the Salone del Mobile give its designers another way to be creative and ultimately produce striking interior style. Ford wants this to be a differentiator, as research shows consumers are placing emphasis on the layout and features inside when they're making a decision about buying a new car. It's a little light hearted – but it's also potentially big business. Other News & Notes Cadillac CT6 platform could be used for Buick General Motors product chief Mark Reuss said the Cadillac CT6 platform could be used for a large Buick, though "not yet," Automotive News reported. The underpinnings can accommodate rear-wheel or all-wheel drive and would give Buick the large flagship it lacks. The report jibes with comments Reuss made at a roundtable with Autoblog and other reporters at the New York Auto Show. When asked if Buick had space for a large car on the CT6 chassis, he replied, "Yeah, I think it does. Yeah, I think we do." Buick has revamped its lineup in recent years with attractive crossovers and small and midsize sedans, but hasn't added the proverbial flagship that's yearned for by enthusiasts. Buick surprised industry observers with the stylish Avenir concept at the Detroit Auto Show earlier this year that raised the possibility of a halo sedan.
