This car is excellent. The quality, fit and attention to detail is great. The reliability is outstanding. Handling great. With 17" tires it sticks like glue to the corners. The car is leading edge producing 134 HP. It uses every bit of energy in the diesel fuel. Temper your MPG expectations, if based on these reviews. The EPA mileage rating is 27/38 and while some are stating solid numbers over 40, those come with caveats. For example, the quality of the diesel fuel. The west coast does not have the true high performance diesel like other areas. These high MPG are obtained on long highway runs. My personal best is 39 MPG. Average commute numbers are 32 MPG (30% city/70% highway).
The tiptronic transmission. It allows you to upshift and downshift at the push of the shift column for control. With the TDI you can downshift to slow the vehicle. This allows for engine breaking using the engine compression, there is no fuel used, which saves your brake pad without hurting MPG.
Turbo lag is noticable, causing a delay when taking off from a dead stop. You adjust to it, but for those used to an immediate acceleration it can be scary when trying to pull out in a hurried situation. Once the turbo kicks in you get pushed into your seat and the car moves wonderfully.
