Yes, this is the diesel
Let me begin my review of the X5 Diesel with this: I’m not much of an SUV driver. I’d much rather drive a car, preferably one with a sporty nature. But I don’t think I’m an atypical enthusiast. You know what I mean. It’s much more fun to drive a car, even with just a hint of performance, rather than a truck or SUV.

The American market has struggled to accept diesel’s, unless it’s a pickup truck. The low-end torque makes diesel power ideal for towing trailers and hauling loads.

But when I heard I’d have access to a BMW X5 for a few days, I hate to admit it but I got excited. I have, of course, read a lot about the X5 and BMW’s take on the world of SUV’s. But I have never driven one, plus this was a diesel. Would driving a diesel be any different than a gasoline powered car or truck? What about the noise? And just how “green” would it prove to be?

What about today’s diesels?
Some years ago, U.S. auto makers introduced buyers to diesel-powered cars with mixed results. Those 70′s era Oldsmobile’s and Cadillac’s emitted such a clatter that it startled most potential buyers to dash the thought of better mileage for smoother running and quieter rides. Still land yachts, just not so noisy.

Any previous opinions I held regarding today’s diesel vehicles were quickly dashed with this X5. Diesel engines have come a long way and BMW has done much to quell consumers fears about engine clatter and smelly exhaust.

Can you tell its a diesel? Well aside from the X5′s graphics, you can when accelerating from a standing start. But the engine is at full grunt doing the job of getting the car up to speed. But standing outside the X5 as it idled or when at cruising speed, it was quiet and smooth.

The diesel X5 comes in two forms, the xDrive 30d or 35d. Each is powered by a turbocharged 3-liter in-line six, with the 35d bestowed with twin-turbos. The 30d has 235 horsepower and the 35d with 286.

BMW’s diesel produces a hefty 425 lb-ft of torque at a low 1750 rpm. It accelerates to 60 mph in 6.7 seconds, impressive for a 5111-lb SUV. For those wondering about mileage, the EPA rates the diesel X5 at 19 mpg city and 26 mpg highway. I easily achieved these numbers, particularly on the highway where my local freeways are relatively flat.

The X5′s handling easily rivals many “sports” sedans and is a ball to drive. The low end torque powers it through corners quite nicely and makes you think you’re driving something other than a heavy SUV. Fun, yes, but the weight will catch up with you with a nod to understeer that is easily controlled and expected.

Electronic gadgetry
Hallelujah, I was able to pair my iPhone with iDrive! Or, more specifically, with the Communications center of BMW’s disputed entertainment hub. I wasn’t so successful with the 3 Series I tested not long ago so I was pleasantly surprised by my success this time around.

What I was disappointed with was the quality of the system itself. The iDrive control knob is nicely weighted and feels like it should be linked to a grade-A entertainment system. Unfortunately, the expected BMW quality ended there. The other buttons used to access the system were a hard plastic that didn’t mesh well with nearby surfaces. The BMW standards guide may need a revisit.

I did find the iDrive system easy to navigate. BMW has taken much heat over the system since it was introduced and has simplified it. To those ends, they may have let the on-screen graphics suffer. A visual update is needed, especially in the age of computer gamers and hybrid “greenness” measuring dash displays.

How about the competition?
You can see how the diesel X5 faired against it’s competition in this comparison published by Motor Trend. Based on their results, Motor Trend favors Volkswagen’s Touareg TDI.

You benefit from German engineering in both the BMW and VW, but the Touareg seemingly wins out with a better designed interior. You want your time behind the wheel to be a great experience, not only in driving dynamics but in the quality of the environment. BMW may be lacking here, but first hand experience will be your best guide.

Any true-blue BMW fans out there? What do you think of a diesel BMW, particularly an SUV? Is it high time American buyers accept diesel, particularly with its miles per gallon advantage? Or will the higher showroom sticker price turn buyers away, not to mention the higher cost at the pump? Let me know what you think, especially if you are an X5 owner.
