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.

2018 Jeep Grand Cherokee vs. midsize crossovers and SUVs: How they compare on paper

In a world full of SUVs and crossovers all competing for similar buyers in similar segments, there are still some models that find their own little niches that lack such fevered fighting. The Jeep Grand Cherokee is one of those vehicles. It's an oddball in the sense that it's a midsize crossover SUV with a unibody chassis and independent suspension, but it still uses rear-wheel-drive and four-wheel-drive systems and has some off-road capability. It's also a midsize crossover, but only offers two rows of seats. Despite the Grand Cherokee's odd nature, we did come up with a few crossovers and a classic SUV that seem to match the Jeep in size and pricing. We looked at the numbers to compare them on paper. You can find the raw data in the chart below and deeper analysis after that. As always, this is just a comparison of specifications and you'll want to check out our driving impressions of each car if you're getting serious about one or all of these vehicles. And if you want to compare any of these against other vehicles, be sure to check out our comparison tool. Engines and Drivetrains When comparing base engines, the Jeep Grand Cherokee's 295-horsepower is the clear power winner, beating the next most powerful 4Runner by 25. But in torque, the 4Runner takes the laurels with 278 pound-feet, narrowly edging out the Edge's (no pun intended) turbocharged 2.0-liter four-cylinder's 275. That four-cylinder in the Edge will also be picking up another 5 horsepower for 2019, but it still won't win this power contest. Both Ford and Jeep also have another advantage in the fact that you don't have to settle for the base powertrain. Ford has two other engine options, a naturally aspirated V6 and a twin-turbocharged V6, the latter of which outguns the Grand Cherokee's gasoline V6 in both power and torque. That engine will also be bumped up to an impressive 335 horsepower and 385 pound-feet of torque.

On most Grand Cherokees, the options include a 5.7-liter V8, which is only available with 4WD. It makes 360 horsepower and 390 pound-feet of torque, outperforming even the 2019 Edge's twin-turbo V6. The diesel engine doesn't make much power with just 240, but it makes up for it with torque at 420 pound-feet. And of course there are the SRT and SRT Trackhawk models with even bigger and supercharged V8 engines respectively.

Toyota Tacoma X-Runner dead

A report from last week indicated that Toyota will begin trimming models from its Tacoma lineup starting with the Regular Cab in 2015, but the popular pickup will lose its first variant even sooner than that. For 2014, the Tacoma X-Runner has been dropped, though the company's SR Package could fill the need of those looking for a sporty pickup.
The X-Runner has been around since 2005 with its lowered stance, aftermarket-look body kit and bright paint colors, all of which are offered available only on V6-powered, two-wheel-drive Access Cab Tacomas. The new SR Package sounds like it will offer a somewhat similar appearance, though, with a monotone exterior paint scheme in limited colors accented with smoked headlights, but it will only be offered on Pre-Runner and 4x4 models. Other changes being made to the 2014 Tacoma include a new wheel option with black finish, a wider variety of Entune multimedia features, and the option to have the backup camera display moved from the rearview mirror to the audio system head unit.
