Tarted-up production cars revealed at the SEMA show aren’t exactly the stuff of shocked gasps and hurriedly sent text messages to friends, but there’s often some useful gear to come out of the annual trade jamboree.

The blue window tinting and wheels on the pair of Blue Line “concepts” trotted out by Chevrolet ahead of the show likely impressed no one, but it’s what lies beneath that matters. Starting next year, the bowtie brand will let owners of its newly redesigned compact gain some extra horsepower in a manner that won’t void the warranty.

Yes, the Cruze is joining the tuner scene.

Hello Sajeev,

This is my second time writing in about my Oldsmobile. I solved the cooling problem with a mechanical fan, however now I am having another problem. As you may recall I swapped in a ZZ4 GM Performance 350 CI motor, and now it will “diesel” for awhile after I shut it off. It only does this after it has had a chance to warm up. Do you have any ideas for fixing this?

Thanks,
Paul
