US Tiguan to Debut Next Gen Engine

Volkswagen has revealed that the brand new Tiguan is coming to the US fitted with the latest generation of its EA888 four-cylinder engine producing 184 hp and 221 lb-ft of torque.

The 2.0-liter engine isn’t only expected to get healthy power figures, it’s also anticipated that it will be 20% more efficient than the current 1.8-liter version of the EA888 in the Beetle, Jetta, Golf, and Passat, although the EPA has yet to officially confirm that.

Volkswagen wasn’t just interested in making the engine efficient in tests, though. The new EA888 gen3B engine uses a modified Miller combustion cycle that’s unique to the automaker. The advantage of the so-called Budack-cycle is that the engine is more efficient during everyday driving.

That’s because the intake valves close earlier, effectively leading to longer combustion and faster air flow on the intake, which improves the mixing of the fuel and the air. That means more torque and more efficiency.

Thanks to variable valve timing, the engine can always choose the best valve timing, be it at idle, while humming down the highway, or under acceleration. That decision is made via VW’s quad core processor engine management unit.

As with all EA888 engines, max torque is produced low in the rev range, between 1,600 and 3,940 rpm, while max (184) hp is produced between 4,400 and 6,000 rpm, 400 revs faster than on the 1.8-liter unit.

The EA888 engine first arrived in the US in 2009 in the VW CC, and this latest generation will find its way into more engine bays than just the Tiguan’s. It is making its US debut next year in the Tiguan, though.

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...

Project SportWagen: Going Stage 2 with APR

When we last left you, the humble little SportWagen was fresh from the development process with our friends at AWE Tuning, sporting a new downpipe, exhaust and intake, allowing things to breathe a bit easier. The car sounded great, but there was no getting around the fact that our wagon was still quite, well, slow. While we realize that nothing we do to the Golf SportWagen at this point will make it a race car, we still felt compelled to do something . To put it bluntly, we had a fever, and the only cure was more power. Flash forward a few hours, and we found ourselves at Waterfest, staring down APR’s palatial spread and the numerous tuned vehicles surrounding it. Earlier in the year, APR had hinted to us that their 1.8 TSI files would be quite impressive, and based on what they were able to do with the 2.0 TSI found in the new GTI and our time in their Golf R, we knew it’d be worth the wait. So with this in mind, we lined our G...

Audi Teases A7 Details with New Video

Audi’s gearing up to unveil the latest iteration of the A7, and to get you excited they’ve released this teaser video focusing on the details. The lights, the lines, the interior are all teased here, and though on its own the video doesn’t give us a strong sense of what the whole car will look like, with all of the other details we’ve seen so far we now have a pretty good sense of what’s coming. As you might expect, the updated A7 will look broadly similar to the outgoing A7, but will differ in the details. Based on what we’ve seen, the changes look good. As was reported yesterday, we’re expecting a 3.0-liter turbocharged engine, a 4.0-liter V8 twin-turbo, a 2.9-liter twin-turbo V6, and an RS7 that could reportedly make up to 700 hp thanks to the Porsche Panamera’s hybrid drivetrain. We’ll know for sure, though, on Thursday, October 19, when the car is revealed. You can watch the livestream on our site or at audi.com at 2:00 pm.
