2017 Audi TT Available Features: Cons
Year	Comment
	This one could go either way depending on which features are important to you. I badly miss one feature in the new TT RS. The 2012-2013 TT RS was offered only with a manual transmission. The new one is offered only with an automated dual-clutch transmission (DCT). While a DCT can shift more quickly, and thus enables quicker acceleration, even the best of them--and those in the Audi and the Porsche rank among the best--are not nearly as engaging as a manual transmission. I didn't enjoy driving the new TT RS nearly as much as I did the previous TT RS, and the transmission change deserves the bulk of the blame. A manual transmission remains standard on the Porsche and the BMW. You, on the other hand, might care more about all-wheel-drive (AWD) than about a manual transmission. The Porsche, which lacks it, can be trickier to drive near its (higher) limits or on slick roads. On the BMW you have to step down from the M2 to the relatively softcore M240i for optional AWD. (And if you get AWD on the BMW, then no manual transmission for you.) Other than AWD, you can get quite a few features on the 718 Cayman that you cannot get on the TT. Notably unavailable on the Audi: adaptive cruise control, forward collision warning, automatic emergency braking, memory for seat settings, and ventilated seats. Porsche buyers can also select from a vast array of interior color and trim options. With the Audi, interior color options are limited to the choice between gray or red contrast stitching. Spend $900 on the RS Design Package, you you get red on the vents and seat belts. Inlays are aluminum or, for another $600, carbon fiber. The rest of the TT RS's interior is unavoidably black. The BMW's interior color options are much like the BMW, but with a choice between blue and orange stiching and without optional vent trim rings. see full Audi TT review
