As for "not rewarding" VW, I would think that the other 650,000 world wide VW employees might feel differently about that. This army of people happen to make quite well engineered cars these days with high assembly standards and not bad design. Get over it.
Fuel cost is only an additional $250 in 14,000 miles per year for the new 1.8t gasser. And, the gasoline 1.8 TSI has solid low end torque. But, that is not telling the whole story by a long chalk when it comes to the changes made to the 2015+ model Sportwagen. VW has just simply lost the thread when it comes to this concept.
In the case of the 2010-2014 Sportwagen, the fact that they were TDI was not the only selling point. In fact, these cars were so special, I sold our 2010 TDI and bought new 2014 TDI, just because of changes unrelated to TDI in the 2015-6 Mk7 Sportwagens.
Basically the 2015-16 Sportwagen is no longer a sport wagon.
1) No more DSG transmission. VW USA must be clueless how desirable this is for an experienced performance driver. 3 second per mile quicker than a manual gearbox and effortless. The gasser has a decent automatic 6-speed, but it is nothing like driving a DSG. I also short shift for excellent fuel economy in town. DSG is made for this use as well.
2) Loss of large, GTI sized front and rear brakes. There are times when smoke just pours off my brakes coming down a mountain. The bigger GTI brake surface dissipates more heat between slowing down for corners. Add ceramic pads, Audi TT front control arms bushings and these are serious performance brakes. There is a reason Bilstein offers their yellow "B6" sport shocks for the 2009-2014 chassis. It can do the job.
3) TDI Sportwagen lost its IRS (independent rear suspension) to a DEF tank. This was sinful. Put the tank up in the rear fender on the left side and keep the IRS. IRS tracks in corners, where the solid beam axle can cause unwanted surprises.
4) The 2015 MK7 chassis no longer has fold flat seats. I bring fitted boxes to job sites, and carry large RC aircraft in that 66 cuft. The 2009-2014 fits a 40 gallon water heater, the 2015-16 does not. Again, what was VW thinking.
I understand the 2017 Sportwagen will have DSG, but only with 4-motion. This only in a stripped model with cloth only, no heated seats, nor driver assist package available. A day late and a dollar short again. The ugly, totally poser AllTrack will also be way over priced. But, it has headed seats, and a better auto-control heater.
How I do wish Japanese and German car makers would just sell Japanese and German sedans without clueless attempts at translation for the American market. They also hire American sales executives who come up through the dealer chains and then trust them to make marketing decisions, all based on feedback of how the dealers want to pack their cars and increase their profit margins. Let those guys sell trucks and leave the sedans alone. Bummer.
