Toyota demos its TRD Pro Series line [w/video]

With a rich history of creating off-road worthy trucks and SUVs and a somewhat bland impression of its brand overall, Toyota has wisely created a line of TRD Pro Series vehicles to spice up its showrooms and newly engage customers. Debuting at this year's Chicago Auto Show before rolling into dealers this fall, the TRD-tuned vehicles include the 4Runner, Tacoma and Tundra, all with added rough-road gear and amped-up looks.
The TRD Pro Series trucks might end up, in many cases, as lifestyle accessories for outdoorsy types, but that doesn't mean they're all show. TRD springs and Bilstein dampers are set up for off-road performance, while skid plates will protect the softish underbellies of these would-be rock-crawlers. The trio all get lifted over stock height, as well, with two-inch gains for the Tundra and Tacoma (lovingly referred to as "Taco Supreme" in the Toyota press release), and an inch-and-a-half rise for the 4Runner.
We detailed all of the changes to the Pro Series vehicles in our original announcement post, and you'll also find more granularity of information in the Toyota press release below. Before you dive in, however, be sure to take in our set of live, action-packed images from the Chicago Show floor.

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.

2019 BMW Z5 shows off its soft top

BMW continues development work on the Z5, which will succeed the Z4 in its lineup for the 2019 model year. These latest spy shots again show off the Z5's classic sports-car proportions during testing on European roads. As expected, the roadster will switch to a cloth top instead of the retractable hardtop the Z4 uses. The much-anticipated Z5 will be based on a rear-wheel-drive platform that's jointly developed with Toyota. Rumors persist Toyota's version will mark the return of the Supra name, though the Japanese automaker has been silent on the matter. Reports say the cars could be assembled by Magna Steyr in Austria. We expect the Z5 will run four- and six-cylinder engines, and the soft top will help the roadster reduce weight and likely improve performance. It's also possible BMW will build a fixed-roof Z5. We predict the Z5 will appear on the auto show circuit within the next year. The long-running Z4 launched for 2009.
