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.

Toyota Prius gets higher clearance, better suspension in Pakistan

It's been 16 years since the Toyota Prius launched in Japan. Finally, the world's most popular hybrid is becoming the first hybrid car to show up in Pakistan. This version of the Prius has been customized by Indus Motor Company (IMC) in order to deal with, well, let's just say some challenging road conditions. IMC knows what it's doing, and has modified Toyota and Daihatsu vehicles for the Pakistani market for over 20 years. The Prius brings with it the iconic shape and Parvez Ghias, CEO of IMC, told The Technology Times that the car's arrival, "is indeed a great milestone, not only in the history of IMC, but, of the entire nation." Pakistan Today says that IMC is beefing up the ground clearance of the imported Priuses and adds a "robust suspension system." Why would this be important? Well, the US Department of State warns travelers to beware of crowded roads, aggressive and poorly trained drivers and bad roads that could include potholes and sharp drop-offs. Then there's the "donkeys, cattle, horse carts, and even the occasional camel [that] can pose roadside hazards in some areas." There's also the big problem of terrorism-related violence in Pakistan, but we haven't heard that the Pakistan Prius has been bullet- and shrapnel-proofed.
