Car and Driver: 2010 Acura TSX V6 Review

How does a big V-6 affect one of our longtime favorite sports sedans?

Around here, we are all big fans of the Acura TSX—the lean, frisky, three-time-10Best-winning, first-generation version, anyway. With respect to the larger, more substantial second-gen 2009 TSX introduced just last year, our camp is split. Some of us believe that even despite the car’s newer and larger (but just 130-pound-heavier) body, the high-revving 201-hp, 2.4-liter four-cylinder carried over is still a great match, offering an excellent blend of power and prudence, especially with the available six-speed manual. The rest believe that along with the newfound size and substance, Acura should have added a heap of horsepower—and rear- or all-wheel drive.

In regards to the former group, nothing has changed on the four-cylinder TSX for 2010: it’s still the happy, front-drive, near-luxe sedan it’s always been. For the power-hungry bunch, the 2010 TSX V-6 will alleviate the horsepower deficit when it goes on sale in July. By slipping in the same, 3.5-liter V-6 from the base TL—tuned in the TSX to 280 hp and 254 lb-ft of torque—Acura turns its smallest four-door into a very quick sports sedan, even if it comes only with a paddle-shifted, five-speed automatic transmission.

BASE PRICE: $35,660
ENGINE TYPE: SOHC 24-valve V-6, aluminum block and heads, port fuel injection
Displacement: 212 cu in, 3471ccPower (SAE net): 280 bhp @ 6200 rpmTorque (SAE net): 254 lb-ft @ 5000 rpm

How quick is it? Well, we’ll have to wait until we track test it to say for certain. Acura says it is capable of hitting 60 mph in seven seconds. But considering we hit 60 in 6.7 seconds with the last manual-equipped four-cylinder TSX we tested, we’re sure Acura is waaaaaay off with that silly estimate. Stay tuned.


Keep Your Hands on the Wheel

But alas, as the saying goes, with power comes responsibility. And in this case, the driver must be responsible for managing the V-6 model’s extra thrust—and 200-plus pounds of additional beef, most of which takes up residence over the front wheels. With its 62/38-percent front-to-rear weight distribution, this is a recipe for eminent understeer. And sure enough, our preview drive on some of the most challenging mountain roads through Malibu, California—with almost no runoff room and very few guardrails—provided us with more than a few intestine-twisting moments. We came to realize that the V-6 model truly isn’t as tossable as the four-cylinder, despite Acura’s fitment of flared-spoke 18-inch wheels (one inch larger than those on the four-banger) and firmer front shocks. Torque steer, however, is very well managed considering how much power is being dumped upon the front axle. After all, the front tires have to steer, too.

The brakes were also worked up a bit, with a new master cylinder, brake booster, and uprated rear brake pads. The pedal, however, still exhibited some slop in the first inch or so of travel, and that only got worse during our admittedly harsh flogging. We also saw considerable fade. In every other respect, however, the TSX is unchanged. The only exterior alterations involve the aforementioned wheels, a slightly revised front fascia and the V-6 badge on the trunk. Inside, other than a new active noise-cancellation system, there is no difference whatsoever. And that’s just fine with us: the comfortable, spacious and exceedingly well equipped interior is one of the TSX’s strongest suits, especially dressed in a dark color and equipped with the Tech package and its solar-sensing climate-control system, 10-speaker ELS surround-sound stereo, and navigation with real-time traffic reporting.

Steep Price for Power
Well, there is one more difference: price. At $35,660, the TSX V-6 will cost a monstrous $5,540 more than the $30,120 2010 TSX four-cylinder that’s available now. That’s right, two extra cylinders will run a guy nearly $2,800 each. That’s especially notable given that the TSX has proven that it can do its job just fine with the four it was born with, to say nothing of that engine’s clear fuel economy advantage (21 city/30 highway mpg versus 18/27).
Hmmm. So how much is all that power—and understeer—really worth to ya?
