Nothing is more American than a high-horsepower V8 in a muscle car. Thanks to increased demand, roads are going to feature more of that familiar V8 rumble as Dodge ramps up Hellcat production.

2015 Chevy Silverado 2WD LT Crew Cab

Just a couple of months ago, GM quietly announced their factory 5 year/100k mile powertrain warranty was going to henceforth be downgraded to a 60k mile powertrain warranty because their cars are all fine now and customers don’t care about long-term warranties.

About 48 hours after this was announced, my wife found herself limping along the side of a major road in our 2010 Malibu with 90k miles on the odometer, engine revving, but little transmission of power taking place between the engine and the wheels.

Cadillac ATS-V

The ATS-V+ rumored by Motor Trend is definitely not happening according to Cadillac spokesperson David Caldwell. The proposed new model would encroach too much into CTS-V territory for comfort.

Here’s what happened overnight.

The 2016 Chevrolet Camaro was introduced May 16, 2015, at a special event in Detroit. The all-new muscle car is approximately 200 pounds lighter than the current model and offers more powerful V-6 and V-8 engines.

“From every angle, you’ll never mistake this for anything but a Camaro,” said Tom Peters, design director for the sixth-generation Chevrolet Camaro. That’s probably because it hasn’t changed that much, at least visually. Yet, under the skin, the new Camaro drops some 200 lbs thanks to its new Alpha platform bones and gains a new base engine – a 2.0L turbocharged Ecotec four-pot.

Sajeev:

Could you/somebody please explain what a “flat plane crankshaft” is in the new Mustang GT350, and older Porsches and Ferraris?

I have seen numerous references to it online and in print but nobody, including Wikipedia explains it in non-calculus terms.

Hi Sajeev,

I saw your call for reader questions for the Piston Slap series, and as a diligent and loyal TTAC supporter/Kool-Aid drinker, I will do my best to do my duty (did I just recite the Boy Scout motto?).

You’ve been kind enough to respond to my previous question regarding the failing health of my wife’s Subaru Outback. By the way, in the spirit of CarTalk’s Stump the Chumps question follow-up feature, we ended up dumping the ailing Outback via Craigslist at a discounted price with a full-disclosure of all the mechanical issues (Love. It’s what makes a Subaru a Subaru…or something like that…). We got a 2nd gen Acura MDX and we actually love it. Take note Subaru.

Anyway, to my question: my daily driver is a 2007 4Runner with the lovely Lexus-derived 4.7 V8. The V8 part is important because in the 4×4 variant, as mine is equipped, the power is delivered to the road through a full-time 4-wheel drive setup, rather than the part-time 2H-N-4H-4L system found in the 4.0 V6 4Runner. We’ll come back to that in a moment.

Hey Sajeev, I got one for you.

Several engines nowadays are set up to operate on half their cylinders under light-load conditions. Would the design considerations for piston rings vary from those normally used for such cylinders that are only used part-time? The question arises in the context of a 2009 V6 Accord that is currently in the Honda dealer’s shop to have the piston rings replaced at the manufacturer’s expense to cure a continual oil consumption and spark plug fouling problem.
