TrueDelta Reviews the Seat Room and Comfort of the 2013 Lexus IS

2013 Lexus IS Seat Room and Comfort: Pros
Year	Comment
2014	Following the Germans' lead, many car makers have been fitting firmer and firmer seats. Cadillac might have once been known for seats you could sink deep into, but those in the ATS are the opposite, with too little give and contours that are far from form-fitting. No fear, Lexus hasn't done the same with the IS. Even the more heavily bolstered seats that are part of the F Sport package lack hard points, which helps them provide a slop-free fit for a wide range of body types. (Oddly, you'll find seats similar to these in some Chrysler people haulers.) Personally, I wouldn't mind a little firmer support, but then I also prefer a firm mattress. Notably, the lumbar support in the Lexus IS is only two-way and the spread of the side bolsters is not adjustable. For four-way lumbar support and adjustable side bolsters (plus somewhat firmer support) you need to step up to the larger Lexus GS. see full Lexus IS review

TrueDelta Reviews the Powertrain of the 2013 Lexus IS

2013 Lexus IS Powertrain: Pros
Year	Comment
2014	Lexus hasn't changed the engines as part of the IS's 2014 revisions. So they continue to offer the same pair of V6 engines introduced with the second-generation sedan, a 2.5-liter good for 204 horsepower and a 3.5-liter good for 306. While the smaller engine adequately moves the IS, it's far less torquey than the turbocharged fours offered by Audi, BMW, and Cadillac. Also, despite weighing less than the 350, the IS 250 feels no more agile. Anyone who cares about driving will want the larger engine. (As such, it makes little sense that the F Sport package is offered with the IS 250.) Even with the big six, brute acceleration isn't the Lexus IS 350's forte. Though the new car can hang with the Cadillac ATS 3.6, you'll experience considerably more shove in an Audi S4 or BMW 335i. Rather, the IS 350 distinguishes with smooth, seamless acceleration. At this price point you won't find a more refined powertrain. An eight-speed transmission new for 2014 (and only offered in the rear-wheel-drive IS 350, not with AWD or the IS 250) lends an assist. Though this transmission promptly selects the optimal gear for the circumstances (aided by new G-force-based artificial intelligence), and fully locks the torque converter in every gear save first, shifts are always smooth, and quite often aren't even detectable. The F Sport package adds rev-matching with downshifts. The 3.5-liter V6 engine surges to a 6,600 rpm red line with a song that is at once refined and exciting. It's far from silent, but any noises that might prove objectionable have been tuned out. The V6s in the Cadillac and especially in the Infiniti sound unrefined in comparison. see full Lexus IS review
