In recent years Cadillac revived its focus on quality and interior refinement, and by nearly all accounts, the 2010 Cadillac CTS-V has a very impressive cabin.
Interior comfort is good in the CTS-V, especially if you’re sitting in front in the well-bolstered leather sport seats or the even better available Recaro seats—finished in a breathable and grippy microfiber—that add lateral support for high-performance driving and supportive thigh extensions for taller drivers. The 2010 CTS-V officially seats five, though four adults is more realistic. Up front, reviewers can't stop mentioning the optional Recaro racing seats, which Autoblog says "have adjustable thigh supports, as well as adjustable everything else." ConsumerGuide reports that the "standard sport seats are comfortable yet supportive in fast cornering," but the Cadillac CTS-V's "optional Recaro-brand seats have handy power-adjustable bolsters to dial in ideal comfort/support ratio."
The rear seats don't receive nearly as much press, but ConsumerGuide finds "adequate rear-seat space, though larger adults will feel crowded" and the "marginal headroom is further reduced by the available sunroof."
The 2009 Cadillac CTS-V is, for the most part, a practical daily driver. However, the Cadillac CTS-V suffers somewhat when it comes to cargo space. ConsumerGuide reports that the "usefulness of the boxy trunk is compromised by a small opening," although the "interior storage includes an average-sized center console and glovebox." Edmunds reviewers agree, claiming that "loading bulky items into the 13.6-cubic-foot trunk is hampered by a very short deck."
Most reviewers are very impressed with the assembly quality and materials used for the 2010 CTS-V interior. Edmunds notes that "materials are high in quality, and the level of detailing in this car is comparable to the top import nameplates." Other reviewers agree wholeheartedly, with ConsumerGuide claiming the "luxury-grade trim rivals the best in this highly competitive class." Road & Track reviewers "particularly like the piano black interior trim," while Automobile Magazine appreciates that "shiny black trim and bits of chrome keep things from looking too dour inside." Autoblog adds that the Cadillac CTS-V has "some upgraded trim like micro-fiber inserts in the seats and around [the] steering wheel that feel rich to the touch and look great."
The cabin is also among the quietest and most refined in this class, and at interstate cruising speeds, you'd hardly know that you're in one of the world's most powerful sport sedans. ConsumerGuide says that "wind noise is well muted, but engine and tire noise are relatively pronounced," but Autoblog differs, mentioning that the exhaust note on the Cadillac CTS-V is "louder than a base CTS but far less than a typical aftermarket exhaust system." Cars.com remarks that "there's a nice exhaust sound when you really lay on it, but the CTS-V is otherwise remarkably quiet for what it is."
