Toyota Yaris Hybrid-R is road-going version of brand's racing technology [w/video]

Did you know that the Yaris is Toyota's best-selling vehicle in Europe? That may help explain to us Americans why the car that's lowest on the company's totem poll here in the US got turned into an all-wheel-drive hybrid track monster for the 2013 Frankfurt Monster Show.
Called the Toyota Yaris Hybrid-R, this three-door pocket rocket isn't just a hybrid making a lot of horsepower - it incorporates technology from Toyota's TS030 Hybrid racecar that competes in the FIA World Endurance Championship series, including the 24 Hours of Le Mans. The Yaris Hybrid-R packs a 300-horsepower, turbocharged, 1.6-liter four-cylinder engine under its hood, which should be enough for most speed freaks, but Toyota pairs it with two 60-hp electric motors at each rear wheel (the same ones used in the production Yaris Hybrid that's sold in Europe). That makes total system output an insane-for-this-size 420 hybrid horsies.
But that's not all, as the Yaris Hybrid-R forgoes the traditional battery pack below the rear seats in favor of a supercapacitor, which can both hold more energy and has a much faster power charge/discharge speed than traditional batteries. Paired with the supercapacitor is a third 60-hp electric motor/generator positioned between the engine and six-speed sequential transmission. Its job is to feed the super capacitor energy during deceleration and direct its power to the rear electric motors when more grip and oomph is needed.

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.

2014 Toyota 4Runner

I recently took the redesigned 2014 Toyota 4Runner for a muddy romp in Pennsylvania. While the mechanical bits and pieces beneath the body-on-frame SUV trudge forward into the new model year with very few tweaks, the truck "receives a rugged new exterior design and interior refinements that add comfort and convenience without sacrificing its hallmark performance capability and excellent value," says the automaker.
A quick visual scan of the 4Runner reveals a new front end with a more "aggressive" and "muscular" appearance (yes, I'm quoting Toyota) that includes new headlights, grille and hood scoop. A roof rack is now standard across all trims, too. While SR5 and Trail grades have a bland color-keyed grille insert that gives the face a monochromatic appearance, the range-topping Limited (shown above and in our gallery) snarls with a silver-plated chin that gives it a bit more character.
New soft-touch surfaces within the cabin provide a more upscale environment and a bright new Optitron instrument panel improves readability and functionality. As before, the SR5 and Trail models arrive with fabric upholstery or optional Softex seats (synthetic leather). Genuine hides are reserved for the Limited trim, which is also fitted with Toyota's unique X-REAS (X-Relative Absorber System) automatic suspension system as standard equipment.
