Dodge engineers trying to shoehorn Pentastar into Dart?

The fact that the Dart's launch has been a pretty dismal affair isn't what we'd call secret. Judging by its mounting inventories and poor critical reception, Dodge's successor to its unloved Caliber has struggled since it hit the market. And while both of those are difficult problems to address, at least their cause is well known - the powertrain.
Even Fiat-Chrysler CEO Sergio Marchionne has acknowledged that the powertrain options in the Dart are substandard, admitting at January's Detroit Auto Show that the powertrains are "less than ideal." Leading with the 1.4-liter turbocharged four-cylinder found in the Fiat 500 Abarth left a bad taste in the mouths of consumers thanks to the laggy engine and dead throttle response (to say nothing of the manual and dual-clutch gearboxes that needed more refinement). The addition of the 184-horsepower 2.4-liter Tigershark in the Dart GT has helped matters some, but apparently Auburn Hills doesn't think it's quite enough.
If rumors are to be believed - get that salt ready - a possible solution may be in the works. A report from Allpar is claiming that Dodge is considering fitting a Pentastar V6 into the Dart's engine bay. As the Mopar-obsessed website points out, the critically acclaimed Pentastar is available in three different sizes - 3.0 liters, 3.2 liters and the original 3.6 liters. We don't get the 3.0 here in the US, but the 3.2 can be found in the new Jeep Cherokee and the 3.6 has been seemingly fitted to every model Chrysler can shoehorn it into.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

Leno recalls '90s showdown with Tim Allen and his mullet

Not many of us have buddies with garages full of classic cars, but that isn't the case for Jay Leno and Tim Allen. Of course, one of the advantages for two guys with such vast collections is occasionally getting to pit their cars against each other. The two comedians did just that in the mid-'90s with a burnout battle on The Tonight Show between Allen in a race-prepped Mustang and Leno in a drag racer. After some time away from regular television, Leno is returning to the airwaves with a Jay Leno's Garage series premiering on Oct. 7 (tonight) at 10:00 p.m. ET on CNBC. Let this clip serve as another taste of what to expect for the new TV show's mix of comedy and cars. After reminiscing about the old days in a gorgeous garage, the comedians get into two modern machines to reprise the classic challenge – after a little trash talk anyway. Don't worry because the YouTube series isn't going anywhere, though.
