The 2009 Hyundai Genesis has an extremely spacious interior—especially in back. “Every single passenger dimension on a spec sheet is more ample in the Genesis than in any of its competition,” said Winding Road. Automobile mentioned that the Genesis qualifies as a "large" sedan according to the EPA, though it doesn’t quite have the rear-seat space of a long-wheelbase 7-Series or Lexus LS.
“The seats are as comfortable as they appear,” said Edmunds, regarding the front seats, “although they lack the kind of firm, highly bolstered Germanic treatment a sport sedan enthusiast might enjoy.”
The Genesis’s cabin is quieter and more refined than most entry-luxury vehicles, according to reviewers. Popular Mechanics mentioned the “thick levels of engine sound damping,” while Winding Road declared, “Wind, road, and engine noise are at or close to segment best.” Popular Mechanics also relished the isolation inside, saying that “there was very little noise intrusion inside the cocoon-like cockpit of this quiet sedan.”
Reviewers were at odds about assembly quality and the fine details of the 2009 Hyundai Genesis. “Fit and finish, stitching, touch, materials, and integration are all very good,” raved Autoblog, keeping in mind the under-$40,000 price tag for the V-8.
“The Genesis isn’t just the best-appointed Hyundai, it’s good enough to be judged against established marques,” raved Car and Driver.
Automobile also lauded fit and finish and the materials used, but pointed to the unconvincing “stitched leather” seats, saying that it would be more convincing “if it were French stitched, with two rows of stitching rather than one.” Popular Mechanics found fault with some of the details on their pre-production test car, including doors that shudder when slammed, and rear shelf speakers that were exposed to the trunk.
TheCarConnection.com's editors could only find a minor flaw or two in the Genesis' upscale cabin. It's heavily reminiscent of the Infiniti M, especially in the center stack, where a wave of silver buttons controls the major functions (there's also an iDrive-like controller that manipulates media and climate controls). The buttons can be hard to pick out from behind the wheel, when you just want to speed up the fan--but the look is sophisticated and rich. Hyundai's entertainment controller made connecting to music in an iPhone a breeze, and its navigation menus seemed far easier to use than some setups. Front seats have ample cushioning, and the back seat has truly adult-sized room; you can cross a leg over knee and still have enough room between it and the front seatback. A minor ripple in a pre-production V-8 sedan with the leather-trimmed dash was the only noticeable flaw on TheCarConnection.com's test vehicles.
