TrueDelta Reviews the Seat Room and Comfort of the 2014 Infiniti Q50

2014 Infiniti Q50 Seat Room and Comfort: Pros
YearComment
2014 Like the G37, the Q50 has one of the roomiest rear seats among BMW 3-Series challengers. On paper it offers the most combined rear legroom, 44.5 inches in the front seat and 35.1 inches in back, about 2.5 more than the BMW and Lexus. But the difference doesn't seem as large as this number suggests. The Audi S4 and Cadillac ATS remain more cramped. The Q50 doesn't come by its extra room through brilliant packaging. Instead, at 188 inches it's about a half-foot longer than a 3-Series or ATS. see full Infiniti Q50 review

TrueDelta Reviews the Seat Room and Comfort of the 2017 Lexus IS

2017 Lexus IS Seat Room and Comfort: Pros
YearComment
2016 For me, the front bucket seats in Lexus F Sport models provide a nearly ideal blend of comfort and support. Even when they don't lack lateral support, the seats in competitors don't fit my form as well. Infiniti doesn't offer the Q50 2.0t in Sport form. The standard car's front seats provide little lateral support. The instrument panel appears larger and more imposing in the Infiniti than in the Lexus. Still, I wish the view forward were a little more open in the latter. (The Cadillac ATS is better in this regard.) Lexus lowered the driving position compared to the previous IS to help the car feel sportier. I raised the seat some to compensate. Adding all-wheel-drive to the Lexus IS (and a V6 engine with it, AWD isn't offered with the 2.0T engine) adds another issue, a large hump beneath the driver's right calf. Some drivers might find they have to adjust how they sit to avoid this hump. see full Lexus IS review
