Toyota to enter modern turbo four-cylinder era with Lexus crossover

Toyota has sat quietly on the sidelines as many of its competitors have armed themselves in recent years with lower-displacement turbocharged four-cylinder engines in an effort to gain better fuel efficiency numbers and flatter power curves. It's a strategy largely shared by fellow countryman Honda, who turned away from offering forced-induction four-cylinder models in North America after its first-generation Acura RDX failed to find buyers. Toyota itself has no lack of experience with turbo fours, having built some humdingers for cars like the MR2 and Celica All-Trac back in the 80s and 90s. It's also offered factory-warranted turbos through its TRD performance parts division more recently.
Now, Automotive News is reporting that the world's largest automaker is finally poised to rejoin the turbo-four production-car fray in North America, but it won't be a sports car that delivers the first force-fed punch, it will be a new small crossover model for Lexus. We first showed you spy shots of the NX last week in mule form, and Automotive News says the small softroader will carry a 2.0-liter turbo four in its engine bay when it rolls on to world markets in 2014 or early 2015. That model, the NX 200t, will be joined by the NX 300h, a hybrid variant. It isn't immediately clear when US buyers will see the turbo model, however, it's possible that the hybrid could bow first - the story quotes an anonymous company source suggesting that Americans might not see the engine offering until sometime in 2015.
AN further posits that the new 2.0-liter will likely supplant the company's 2.5-liter V6 in the IS sedan and the same-displacement four-cylinder in the Toyota RAV4, but does not indicate where the new engine will be built.

2013 Toyota Avalon Hybrid

People, us included, make a big stink about the importance of family sedans. There's no doubt they're critical - they represent a huge slice of the market's annual sales and profits. However, despite accounting for far fewer transactions than the midsize sedan segment, the fullsize sedan is getting attention from manufacturers now that our market's entire lineup of those (slightly) smaller four-doors has turned over in the last two years or so. As most of the fullsize segment's mainstays derive a fair bit of their platform and powertrain technologies from their midsize cousins, these larger four-doors offer the potential for fatter profit margins, too. And with the newly stylish duds found on many of the industry's most successful midsize sedans, it's only right that automakers no longer think about fullsizers as big, squishy, vanilla family haulers with flat seats, vague steering and a thin layer of 'luxury' in the form of faux wood trim.
As manufacturers have again started diving into large sedans feet-first, the cars themselves have become sharper. The interiors are now of a higher quality and loaded with tech, while the exteriors have become further extensions of each manufacturer's design language. There's perhaps no greater example of this than the Chevrolet Impala and Ford Taurus, two models that evolved from subpar offerings into market leaders. This segment-wide transformation happened quite quickly, whether because of coincidental timing or because manufacturers are trying to get more out of their big cars, recognizing they account for a small portion of overall sales (just 3.5 percent of the new-car market in the first half of 2013).
The 2013 Toyota Avalon Hybrid is one such vehicle. We remarked on the changes to the V6 variant last year, and while we previously had a quick steer of the gas-electric hybrid, we figured the new model was worth a closer week-long look.

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.
