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.

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.
Road & Track has found evidence, courtesy of an SAE paper, that the 6.2L supercharged V8 from the Challenger SRT Hellcat, will make its way into the Charger.
For over a year, Fiat Chrysler Automobiles has been working on a Hemi V8 dubbed the Hellcat, which set to debut in a revised Dodge Challenger. However, the Hellcat could prove a challenge to the SRT Viper’s V10, possibly unseating the venerable monster from the throne.
114 car dealers. Every single last one of them looking for an impossibly good deal among the 150 vehicles at the auction on a near-Arctic Monday morning.
Even if it’s a seemingly bad deal. It doesn’t matter during this time of year.
This is officially tax season… which means that cars that couldn’t even get a $500 down payment during the post-Christmas drought will soon be picked up in earnest by the sub-prime, debt happy public. A $1200 down payment as their first financial tombstone of 2014 will be followed by a long line of bogus fees, and a note that will hopefully be flipped into funny money (now known as sub-prime asset backed securities) before the drowning debtor becomes financial roadkill.
Everything is high. But surprisingly not as high as in years past. Orphaned brands are mostly cheap. Minivans are cheap, and everything from older luxury coupes to younger hatchbacks can be had for decent money if they’re not sporty or popular.
Speaking of popular. Let me show you a little somethin’.
Car shopping used to be so simple: you could buy a truck or a car. Then came the wagon, minivan, sport utility and the latest craze: the crossover. There’s just one problem with the crossover for me however: it’s not a crossover. With a name like that you’d assume that a modern crossover blended the lines between a truck/SUV with a car/minivan. The reality of course is that the modern three-row crossover is just a front-driving minivan that doesn’t handle as well or haul as much stuff. In this sea of transverse minivans in SUV clothing lies just one mass-market vehicle that I can honestly call a three-row crossover: the Dodge Durango. Instead of a car that’s been turned into an AWD minivan with a longer hood, the Dodge uses drivetrains out of the RAM 1500 combined with a car-like unibody. While rumors swirled that the Durango would be canceled in favor of a 7-seat Jeep, Dodge was working a substantial makeover for 2014. (Read More…)

Hi Sajeev, I have something here for you and my fellow B&B to ponder over,
Back in May I bought a rust-free 1999 Dodge Dakota Sport (Extended cab, 3.9L Magnum V6, 5speed AX-15 manual, 2WD, 3.21 8.25″ open axle) for $2000 from a guy in South Philly. I bought it so I could take my rusty 1992 Dakota off of the road so my dad and I could fix all of the rust on it. Well now the ’92 is on the road (and growing more rust) and the ’99 is sitting on the street with a supposed ticking time bomb in the trans tunnel. When I bought the truck I was told by the previous owner’s mechanic that the throwout bearing was going out and would need replaced soon. Lo and behold, the next day while beating around in it I had to call AAA when I could no longer shift it (and when the clutch suddenly didn’t do anything, made stopping interesting). $600 later I had a whole new clutch kit and was on my way.

If you want a high performance SUV today, you’re left with relatively little choice. GM hasn’t dabbled in the market since their Trailblazer SS / Saab 9-7 Aero and Ford never even gave it a try with the old Explorer. That means your only options for ridiculously fast boxes on wheels come from BMW, Porsche, Mercedes… and Jeep. Is it possible that the “bat-shit-crazy” Chrysler that I remember and love is back?
My father and I are Pontiac Fiero people, as we have owned nine Fieros in the past ten years (my first car was a 1986 Fiero GT). We are quite mechanically familiar with them as we have done little to major work on all of them. My dad currently has a 1988 Fiero Formula that we did a complete restoration on about five years ago. That car is an absolute blast to drive as the stock engine was modified to make considerably more power. After spending last summer driving that car almost every day I knew that someday I wanted a Fiero like his. (Read More…)
