First Test: 2010 Hyundai Genesis Coupe 3.8 Track


Just a year ago, Hyundai pulled out the red carpet to launch the Genesis, a rear-drive, V-8-motivated luxury car with power and grace akin to that of a Lexus LS 460. Its pricetag, however, resembled the one dangling from the rearview of a Chrysler 300C. And wouldn't you know it, just as the original Lexus LS did 20 years ago, the Genesis garnered much attention, plenty of love, and due respect.

It certainly got ours. In fact, had it not been for the extraordinary Nissan GT-R, the Genesis would be reveling in Motor Trend Car of the Year glory for the next seven months. Suffice it to say, the Genesis is one of several top-notch products coming from the now formidable Korean brand.

Don't believe us? Well, Hyundai was one of only four automakers to sell more vehicles in January 2009 than it did in January 2008. In other words, in a month when such terms as "Great Recession" were floating around and Chrysler's sales were down 54.8 percent, GM's 48.9, and Toyota's 31.7, Hyundai's were on the rise. Baby steps? Hyundai is making giant strides.

One such stride -- and it's a big one, especially considering Hyundai's sportiest vehicle to date was the 172-horsepower front-drive Tiburon -- is the all-new 2010 Genesis Coupe. Just as the Genesis sedan's mission was to boldly lead Hyundai into the luxury-car arena, the Coupe's is to unabashedly storm the sports-car field. What's the formula? Try 300-plus-horsepower, rear drive, and styling that'll startle a Town Car. But does it work? Let's explore.

Transmission choices for the Genesis Coupe, which is built alongside the sedan at Hyundai's Ulsan, Korea, assembly plant, include a Hyundai-sourced six-speed manual and a ZF six-speed automatic. The manual utilizes a sporty 3.54 axle ratio while the auto, also used in V-8 Genesis sedans, gets an even more dynamic 3.73 as well as steering-wheel-mounted paddle shifters. Saddled with curb weights within just four pounds of each other (the 3478-pound manual vehicle, surprisingly, weighed more than the auto car), the two 3.8 Track models each hoofed from 0 to 60 in 5.5 seconds, with the negligibly lighter and more aggressively geared auto car clipping the quarter mile two-tenths sooner, at 14.0 at 101.0 mph.

This is a quick coupe, for sure -- a Jag XK needs 5.8 seconds to reach 60 and to 14.3 at 98.3 to nab the quarter -- but not as brisk as several others in its class. The 370Z, 135i, and Mustang GT all put up better numbers. Maybe the onus falls on the engine. The so-called "RS 3800" V-6 (for Rear-drive Sport), which does emit a pleasing growl as it revs effortlessly to the 6500-rpm redline, is no-doubt a refined engine -- arguably more refined than Nissan's VQ -- but it doesn't seem 306 horsepower strong. "I realize that on paper this is a 300-plus-horsepower car," says associate editor Allyson Harwood, "but it doesn't feel like it. It was pretty quick off the line, but I guess I expected a little more thrust."

The six-speed manual also was a bit of a letdown. Its rubbery feel generally led to imprecise experiences, especially when attempting to shift quickly, and its placement on the center console seemed an inch or so too rearward. An RX-8's gearbox will make you jealous. And as editor-at-large Arthur St. Antoine notes, our manual test car suffered from "Lots of driveline lash, making it very difficult to execute smooth shifts and throttle inputs." The manual, alas, left us feeling that the proven ZF slushbox is the transmission of choice, certainly in light of the standard paddle shifters and generally quicker acceleration times.

The last-generation BMW M3 was, and still is, a fantastic GT car. No person in his right mind could say its structure felt like soggy fettuccine. Well, according to Hyundai, the Genesis Coupe boasts a body 24 percent stiffer in bending rigidity than that of the E46 Bimmer. Better than an M3? In this instance, it appears so.

We all agreed the Genesis Coupe feels sapphire solid. Build quality seems first rate. The doors shut with a reassuring thump. Whether navigating a straight highway or a winding byway, the Hyundai comes across tight and well put together. This overall feel of solidity, of course, is a welcome plus, as it not only gave Hyundai engineers a strong starting point, but it also provides the driver with quicker and more communicative responses. Within these realms, the robust Genesis Coupe mostly succeeds. The front strut and rear multilink suspension can be best described as modestly stiff, thanks in part to our Track model's sport-tuned gear, which flaunts firmer springs, larger front and rear anti-roll bars, and 19-inch alloys with summer Bridgestones. The ride is never jarring, but it does act unrefined at times, occasionally crashing onto its bump stops and relaying a wee too much road granularity.

Present the Genesis Coupe with a curvy road, though, and the tautness of the track-tuned chassis pays dividends. The steering, with its relatively rapid 14.7:1 ratio, offers crisp turn-in and solid linearity, but disappoints with a somewhat gluey feel. When the pace quickens, the Hyundai displays modest roll and understeer, but its instinct to stay flat inspires confidence when exploring the limits. Speaking of limits, the Genesis Coupe's standard stability and traction control can be turned completely off. But unless you're impersonating drift champ Rhys Millen, it's probably best to leave that button untouched, as the Track's Torsen LSD can't cheat the laws of physics.

In our instrumented handling tests, the 3.8 Track cars recorded lateral acceleration of 0.90 g (manual) and 0.91 g (auto), and figure-eight runs of 26.2 seconds at 0.67 g and 26.3 at 0.68. Again, these figures outgun those of the upper-echelon Jag XK (0.89, 26.8 at 0.66), but not of its two main rivals, the Mustang GT and 370Z. Ditto for 60-to-0 braking, which, at 111 feet, is just shy of the spans from the Ford (108) and the Nissan (109). As usual, credit goes to the Track model's unfaltering Brembo braking system, which uses meaty monobloc fixed calipers and substantial 13.4-inch front/13.0-inch rear vented rotors.
