Acura Rl Alternator

"The most fun you can have with an Acura RDX is driving it through corners like a sports car. It does a really great job of this. The paddle-shifting transmission shifts smoothly and obeys your input, except when you downshift at an engine speed it thinks is too high, or upshift at one it thinks is too low. But at least it tells you that it's rejected your input by flashing; other systems indicate the car is in the gear you've chosen, even if they don't shift to it.

This is the first turbocharged car Acura has ever made. The 2.3-liter engine is about as high-tech as they come; Honda has been the technology leader with small engines for a long time. The turbocharger changes the power characteristics quite a lot from the more peaky Acura TSX, although it doesn't smooth out the engine. There's 260 pound-feet of torque, and no turbo lag, but when the transmission is in Drive, it kicks up and down when you're driving casually uphill. To stop it, you have to use the Sport, or manual, mode.

During that stop-and-go freeway traffic, we found it difficult to accelerate smoothly. Acura invented drive-by-wire throttle, and, because so many other cars with this electronic system also have hair-trigger throttles, we wonder if the system still has a ways to go.

A bigger flaw than a quick throttle or unsettled transmission is the ride. Our leggy passenger, now sitting in front, said she could feel every bump, especially on the freeway. We could feel them too. It was like a jolt, over the freeway ridges.

Of course, this firmness in the suspension enables the RDX to perform like a sports car around the corners. Acura boasts that it will out-corner a BMW X3, which was developed on the Nurburgring circuit in Germany. So, good for the RDX. But is it worth the trade-off, if the suspension can't also offer a comfortable ride on the freeway? Maybe; you decide.

We left our RDX in California and got in another RDX in the Northwest, just in time for snow and ice. We tested the ABS by slamming on the brakes going down a steep hill with hard-packed snow at 20 miles per hour. The response was beautiful; it took a long time to get stopped, maybe 100 feet, but we were able to steer anywhere we wanted to, without sliding, while our foot was mashed to the pedal (as we watched 10 inches of snow slide off the roof and down onto the hood). We should point out that the P235/55R18 Michelin Pilot tires are considered "high-performance all-season," meaning they weren't made for this sort of thing.

Then we went to a slushy parking lot, and tried to cut donuts at hard throttle, to test the stability control, called VSA. The RDX just turned its tight circles, 39.1 feet, without sliding. Pretty amazing."
