VW’s New EA211evo Brings First Variable Vane Turbo to Mass Market

Car and Driver is reporting today that VW’s new 1.5L EA211evo four cylinder engine will produce up to 150hp while using 10 percent less fuel than the engine it replaces.

Despite that efficiency, Volkswagen is aiming to make its new engine the industry benchmark for responsiveness and it’s doing that by using some very high technology.

That technology ranges from the fairly common cylinder deactivation, to the very uncommon variable turbine geometry turbo. In fact, this is the first mass market gas engine to use the technology.

The technology allows the engine to reach maximum torque about 35 percent quicker than with a conventional turbocharger, which helps make it more responsive. Currently, it’s only available on the Porsche 708 Boxster S and the 911 Turbo—as far as gas engines are concerned.

Tiny details are also important in Volkswagen’s pursuit of high efficiency and responsiveness. The cylinder linings of the new engine, for instance, are sprayed with an atmospheric plasma spray to make them even slipperier.

For now, the new efficient engine is only available in the entry level Jetta and Jetta Hybrid, but Car and Driver are reporting that the new EA211evo is arriving in Mexico’s Silao plant soon, so there are hopes that the engine will become more common.

2018 Lamborghini Aventador S Roadster Review

“Supercars just don’t excite me anymore.” These words, spoken to me over a month ago by another journalist, friend, and (so-called) enthusiast were echoing in my head for far too long, but they’ve finally been drowned out. Drowned out by the wail of a naturally aspirated 6.5-liter V12 engine mounted in the middle of the new Lamborghini Aventador S Roadster. My friend’s point is that back in the good old days, there was a crop of supercars that captured the imagination with amazing style, sounds, performance, and more. Today, it seems like everything is capable of supercar performance, with large luxury sedans outdoing some of the best and most dedicated teams of car nuts, while former pillars of automotive excellence are suddenly pumping out family-friendly SUVs. Beyond that, another league of supercars, dubbed hypercars have cropped up with hybrid gas-electric powertrains that make magical things happen quickly, but at the cost of the acoustic drama, visual flair, and engag...

PZM 73rd Rally Poland Kicks Off

The WRC is in Poland and after only one stage there are three Volkswagens in the top five. Today’s special stage at the Mikolajki Arena is the first stage, but the rally doesn’t begin in earnest until Friday. Today’s super special stage was less than two minutes long, and less than a second separates the top five drivers. Hyundai Motorsport’s Thierry Neuville tops the charts today, followed closely by Volkswagen’s Andreas Mikkelsen. Sebastien Ogier and Jari-Matti Latvala are in fourth and fifth, respectively. Expect Ogier to climb the rankings, though. Not only did he win the rally last year, he has won every year since 2013. And with rain expected on Friday, Ogier’s chances are even better. “If it’s a bit wet then I hope I can make some good times,” said Ogier earlier today. “The best would be some good rain during the night so it’s a damp surface and then not too bad weather during the day so specators can enjoy the show without being too wet.” If it is dry, though, speed is on ...
