The brand new Audi TT RS appears like an more and more competitive prospect. Just like its rival Porsche 718 Cayman falls to four cylinders, the TT RS doesn’t only keep its charismatic straight-five, it will get a redesigned form of it. And much more power.
The headline is indeed a grabber – 500 horsepower. A minimum of that’s if you are ready to use metric horsepower, the PS sort. In bhp, it’s an untidier 395.
But there’s some underlying news that’s much more interesting. The brand new engine is really very new. It makes sense lighter compared to old, for much better handling, and keener to rev.
It’s switched from the cast-iron crankcase – although an extremely fancy compacted vermicular cast-iron – for an aluminium one. This transformation saves 18kg, and really the entire engine is 26kg lighter compared to old one. New intake systems and pistons mean it’s worth hanging to the gears longer, as peak power is sustained completely to 7000rpm. Within the former TT RS and also the current RS3 5-cylinder engine tails removed from 6500.
It’s significant that Audi’s RS division is ready to put money into an electric train engine it is not utilized in any non-RS models. An electric train engine that’s unfashionably large, unfashionably multi-cylindered and unfashionably special.
Fashion might be swinging back its way, a minimum of when the official fuel consumption test changes. Porsche dropped the cylinder count from the 718 series to look great in the present fuel test cycle. But it’s becoming more and more apparent this cycle is impractical, which a far more relevant cycle will come up before too long. Inside a real-world test, 5-cylinder could do okay.
We spoke to Annette Möllhof, the Ingolstadt product planner responsible for all of the five-cylinder Audis – RS3, RS Q3 and TT RS. Performs this engine mean 5-cylinder won’t die, as numerous had morosely predicted? She states it features a vibrant future, and also the Quattro division are ‘actively looking’ for other programs. She won’t say what, but states the brand new engine is identical physical shape and size because the old one.
Therefore it would appear incredible if your facelifted RS3 doesn’t have this engine promptly. And most likely any RS versions from the new Q2 and Q4, along with the Q3’s substitute.
Incidentally, you may remember in March 2014 in the Geneva motor show, Audi revealed an idea known as the TT Quattro Sport (pictured below). Lots of people thought its job ended up being to show us exactly what the TT RS would grow to be. It were built with a 420bhp four-cylinder 2.-litre engine, along with a body widened by 3cm.
TT Designer Dany Garand told Top Gear today he might have loved the TT RS to possess got the broader body, however it was too costly. We didn’t have that, but we ended up getting a 5-cylinder engine rather than a four.
