Toyota reveals new TS040 Hybrid LMP1 [w/videos, poll]

There's a new season of motor racing upon us, and while that doesn't always mean a new crop of cars in every series, in the case of the 2014 FIA World Endurance Championship, that's exactly what it means. Porsche recently revealed its new 919 Hybrid and Audi its revised R18 E-Tron Quattro. Now it's Toyota's turn.
Revealed today at the Paul Ricard test track in the South of France, the new TS040 Hybrid is based on the TS030 Hybrid it replaces, redesigned to meet the latest regulations established by the FIA and ACO for the World Endurance Championship and its flagship race, the 24 Hours of Le Mans. In accordance with said regulations, the TS040 is two inches narrower than the TS030 and also incorporates a new hybrid powertrain.
The previous 3.4-liter V8 has been replaced by a 3.7-liter V8 developing 513 horsepower, and the new engine is coupled to an Aisin AW electric motor at the front, a Denso electric motor at the rear and a Nisshinbo super-capacitor that combine to kick out an extra 473 hp, giving the system a combined output of nearly 1,000 horsepower while consuming 25 percent less fuel than last year's car. It also gives the TS040 all-wheel drive to help channel all that power to the road.

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.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.
