TrueDelta Reviews the Seat Room and Comfort of the 2018 Audi A4 / S4

2018 Audi A4 / S4 Seat Room and Comfort: Pros
YearComment
2017 Before the 2009 model year redesign, the Audi A4's back seat was too tight for adults of more than average size, and marginal even for these. With the 2017 the back seat has grown yet again. Not only this, but the cushion is higher off the floor than in previous A4s or in competitors, such that it's now the most comfortable in the class. This said, the rear doors could open more widely, such that I struggled to get a decent photo of the rear seat. Since its 2014 model year redesign the Lexus IS has had a passably roomy rear seat, but it can't match the Audi's for comfort. see full Audi A4 / S4 review

Pressed to come up with another con, I might offer the front seats. There's nothing bad about them. There's just nothing outstanding about them, either. Those in the sport-trim Lexus provide more lateral support and feel more comfortable to me. (With seats personal impressions are bound to vary, so definitely evaluate them yourself.) see full Audi A4 / S4 review

TrueDelta Reviews the Powertrain of the 2018 Audi A4 / S4

2018 Audi A4 / S4 Powertrain: Pros
YearComment
2017 Audi led the way to turbocharging, fitting most of its cars with turbocharged 2.0-liter four-cylinder engines about a decade before everyone else followed suit, and the make's latest such engine will leave few drivers feeling the need for more cylinders. The new engine, rated for 252 horsepower (up from 220) but feeling stronger, accelerates the new A4 very quickly once its turbo has fully come on line. Magazines have achieved zero-to-60 times in the low 5s, a stat that required a V8 not too long ago. One downside with the new engine: boost doesn't come on as immediately or as seamlessly as in the old engine. This should be expected, since a higher output requires a larger turbo (unless a second turbo or a supercharger is also fitted, and one hasn't been), and larger turbos take more time to spool up. Last year's eight-speed automatic has been supplanted by a seven-speed dual-clutch automated manual transmission ("S-tronic" in Audi parlance, "DSG" in a VW). Though this tranmission sometimes feels a touch unsmooth when creeping (typical of the type), in most driving it responds extremely quickly and with the refinement premium car buyers expect. Lexus was nearly the last to hop on the 2.0T bandwagon, fitting the IS with such an engine only last year, and even now only with rear-wheel drive. Opt for all-wheel-drive (as in the tested Audi) and the Lexus gets an unboosted V6. The Lexus four doesn't feel nearly as strong as the Audi's despite a minor 11-horsepower difference on paper, and it's eight-speed automatic, while very smooth, isn't as responsive. see full Audi A4 / S4 review
