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.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.

Toyota's HaMo urban mobility carsharing program comes to France

We're guessing no one's nuts enough to try to take one of Toyota's three-wheeled leaning electric i-Road vehicles up into the French Alps. Still, the town of Grenoble, France, which sits at the foot of the mountains, has received 35 of those vehicles as part of a carsharing pilot program. Toyota's thrown in 35 four-wheel Auto Body COMS vehicles into the program as well. Grenoble, which is about 200 miles north of Marseille, was presumably chosen because of existing carsharing programs run by Cite-lib. This program, dubbed "Cite lib by Ha:mo," goes a little more futuristic, though, as it's part of what Toyota calls its "Ha:mo" plan (Ha:mo is short for "harmonious mobility"). The program will run for three years and includes 27 charging stations near bus lines and train stations. The public will be charged anywhere from three to 19 euros ($3.80 to $24.50 US) to use the vehicles for between 15 minutes and four hours. The good news is that drivers can pick up the vehicles in one location and drop them off in another. Toyota started testing the i-Road vehicles in Toyota City, Japan, this past March. The trike is about three feet wide and has a top speed of 28 miles per hour. Check out Toyota's press release below and read AutoblogGreen's "First Drive" impressions of the i-Road here. "Cite lib by Ha:mo", a New Type of Urban Mobility Based on Ultra-Compact Electric Vehicles Connected to Public Transport, Launches in Grenoble, France This innovative car-sharing service aims to prepare the City and agglomeration of Grenoble for electric mobility within a comprehensive multi-modal mobility plan. The three-year trial project brings together the competencies and services of five partners: the City of Grenoble, the Metro Area, French electricity company EDF and its affiliate Sodetrel, Toyota, and Cite lib, the local car-sharing operator. 35 three-wheel Toyota i-ROAD and 35 four-wheel Toyota Auto Body COMS will be available for short city trips in 27 charging stations installed and operated by Sodetrel - including for one-way trips from one station to another. A total of 120 charging points for the project and 41 for other plug-in vehicles will be added to the city's transport infrastructure. A simple pricing plan dubbed "3, 2, 1 euros" for respectively the first, second and third 15-minute increments will be proposed to Grenoble citizens.
