DI engines have had this problem for several years, with the euro engines possibly having the most buildup.
 
That issue concerns me as well. My 2007 Mazdaspeed3 produces adequate power(287 bhp with a Mazdaspeed CAI) and returns good fuel economy(25 mpg-30 mpg, depending on driving conditions), but the valve deposit issue makes me hesitate to keep it past 100,000 miles.

#14 of 20 Ecotec II review by steve_ HOST

Good review of the new Buick Regal CXL Turbo engine in this Wall St. Journal story, but most of the info may be registration only.
 
"The engine—intercooled, direct injection, 16-valve—is punchy, eager, with ample low-end torque (258 pound-feet at 2,000 rpm) and the kind of seamless flexibility across the rev range you'd have expected from larger, naturally aspirated engines. You can thank the clever engine-management software, and variable valve timing, for that.
 
And the car is quick. If you stand on the gas, the Regal Turbo will chirp and wiggle its way to 60 mph in about 7 seconds, quite respectable for a car weighing nearly 3,800 pounds. At highway speeds it has surprising reserves of orneriness. "

Good article, Steve, but it contains a mistake; the Hyundai Sonata turbo displaces 2.0 liters, not 2.4, which is the displacement of the naturally aspirated Sonata. The Sonata turbo generates significantly more horsepower and torque than the Regal Turbo (274 vs. 220 and 269 vs. 258, respectively), while delivering better fuel economy. The Sonata also beats the Regal on price. All this doesn't necessarily mean that the Sonata is the better car, since the Regal may have some compensating attributes, such as refinement, over the Sonata. We'll soon find out, since I imagine there will be a comparison before too long.
 
Also, at 3800 lbs., the Regal is porky for its size, don't you think?
 
I wonder how many people will cross shop the Regal and the Sonata?

In my town, people will only shop Buicks. I see one foreign car for every ten Big 3 rides.

I live near Louisville, which has two Ford assembly plants, I'd say that the domestic/import ratio is 50/50.

And within a few hundred miles of us we have a huge Toyota plant (in state) and a huge Honda plant (Indiana)...I agree with you--somewhere around 50/50.

I know a couple of guys who work at the Chamberlain Lane Ford plant. Both guys have Ford pickups, but one guy also has a 3 Series and the other guy has a Camry.
