I try to set aside my own bias and have opinions of cars that are founded in fact. If I have never seen the car in the metal, I reserve judgement and speak only of what I can see.
I've never been inside a Passat. I don't know how huge or not huge it is. All I can see is that a 150hp, 236 ft-lb diesel engine is being priced similarly to (if not higher than) the V6 or Turbo models of its competitors. Yes, the diesel is considered an "upgraded" engine, but consumers are essentially asked to pay more to spend less (i.e. pay more for the engine to spend less on fuel). This makes sense when the diesel is far more expensive than the engine it replaces, but I question the cost of the TDI over the 1.8T...I mean, both are turbocharged, so you can't claim more expensive that way. Both have the same # of cylinders - and yes, the TDI will be more expensive for the thicker block, DEF treatment plumbing, etc.
I think VW is trying to become a "premium" brand over its competitors...positioning itself, like Buick, as above the masses, but below the luxury. That's fine, but then I have to see what 'more' you get for your buck. $36,000 is a lot of money for a bread and butter mid-size (or large, whatever blurred category it now falls into), diesel or not. I don't praise the Ford Fusion - I don't like a lot about it - but for $36k, you have every option ticked, including HIDs, AWD, the more powerful 2.0T, and others. So, my criticism of the Passat, which I have never seen, touched, driven, or otherwise experienced, is that its price alone would be a hindrance to it making my shopping list. If I came in with $36,000 to spend, and I wanted a mid-size car, I would look for the one that took my $ the farthest. Whether that's looking for high resale value (Passat, Accord), high feature content (Fusion, Sonata), AWD capability (Legacy, Fusion), etc., I would adjust the number of cars I test drive accordingly. At $32,000 for the loaded 1.8T, I'd be intrigued, but at $36,000 for the TDI, I feel like I'm getting ripped off.
I mean, don't get me wrong, I love diesels, and I am willing to pay a bit for them, but that's over and above the base 4-cylinder engines that are underpowered. When comparing prices, I will pay $3,000 more than the 170ish-hp engines for a 150hp diesel, but I won't pay $3,000 more for the TDI over the 240hp 2.0T in the Fusion AWD or the 3.6R in the Legacy AWD.
