Its a nice engine though, with the benfits of a lot of torque at low rev and a lot of power fromt he turbo at high rev

Until I hear problems of it for myself, the 1.4TSI remains as an engineering feat for me.

Well, you first have to find somebody who owns a car with this engine...at especially with the 125kW version this is not easy.

And also, looking at every turbocharged engine with more than 100 hp / l you see that they are not highly reliable / have no long life...wether it's a Subaru, Mitsubishi, GM, VW or whatever engine.

Per Naruto's request to add this post in his thread:




SPECIFICATIONS (European model, US Specs TBA)

Basics

Type: 90 degree quad-cam four-valve V8.

Size: 4.0 Liters, a nice starting point for the first model year.

Torque: Only 295 ft-pounds of torque (400 N-m) at 3,900 RPM, sadly less than a BMW 540. Torque is at least 251 ft-lbs (340 N-m) from 2,000 to 6,500 RPM. BMW uses this weaker torque to let it use lighter drivetrain components to save weight. This V8's torque is barely 10% more than the old six.

Horsepower: 420 HP at 8,300 RPM.

Redline: 8,300 or 8,400 RPM, depending on where you read it in the press release.

Compression Ratio: 12:1.

Displacement: 3,999 cc.

Bore and Stroke: 3.62” (92mm) bore x 2.96" (75.2mm) stroke.
