Had yesterday off so attended the Chicago event in the early AM before it got too hot ... They had the cars (it looks the best in red IMO) parked right at the intersection of Michigan and Madison so lots of foot traffic; too bad that there is so much road construction downtown but they made the most of it. Inside they had some fairly decent tech set up to feature the new engine and battery tech being used. They also had a virtual reality drive in Recaro car seats that was kind of cool (can't wear glasses using it so a bit fuzzy for me).
As far as the A3 e-tron, quite nice, excellent interior materials, the MMI was pretty easy to use and despite how quiet our LEAF's are this Audi takes things to another level. The car is quite quick and pretty seamless as it switches between driving modes (all electric, combo gas/electric, charging the battery mode, etc.) , handles like an Audi should and in this 'sport back' mode, offers a bit more rear seat headroom over the A3 sedan plus some more cargo space.
It's not cheap, but then it's not in Tesla territory either, love the newer style front end grills that all the new Audis are sporting and like most German mfg's, these are solid, love the 'thunk' when closing the doors, etc.
Would I buy one ... well, the estimated 30 miles on 100% electric is more like 10 to 15 in highway driving, perhaps a bit more in stop & go traffic, as always YMMV. The neat trick it has is that the gas engine can charge up the battery while you're driving and the regen is adjustable on your driving mode and may be similar to what people have experienced on an i3 (to some degree); at least more aggressive than my '12 LEAF. If I could reliably get a true 29 to 30 miles on my daily commute, it could go all week without ever using gas, I'd not expect that on really hot or cold days with snow, but perhaps it's not quite there yet.
Also, ideally I'd like something perhaps just a bit bigger and would miss the higher ride height I've got with my trip car so plan to wait to see how they tweak this on the Q7 e-tron. It's Audi's first in the U.S. that's a plug-in so we'll see ... any one else take the drive, the guys who road with us just came from the NYC event so perhaps someone out east took advantage?
Overall, this was a well run event, the car offers another choice we didn't have before, I'm sure we'll have even more options as long as there is enough interest; in light of the cheap gas prices I'm sure they may question their timing but let's face it, eventually gas prices will go back up but that may postpone some mfg.'s from releasing some models we've only seen prototypes of.
Audi rep's say we should see these next month, hopefully they will tempt even more people considering PHEV's; if you enjoy driving, it's worth checking out.
