Before Jay Leno, this 1970 Dodge Charger was a SEMA star

When Jay Leno drives an awesome car, enthusiasts take note, and this week the internet blew up over the 1970 Dodge Charger resto-mod that starred in a recent Garage episode. But you might not remember: this strapping Charger, called "Tantrum," was one of the highlights of the SEMA Show in Las Vegas last fall. Here's another look at a true Mopar monster. The power: Yep, Tantrum has 1,650 horsepower. That's more than two Hellcats worth of power under the hood. It's a twin-turbo 9.0-liter Mercury Racing engine with a quad-cam four-valve setup. Basically, it's a V8 boat motor developed for cars. Mercury Marine is the crew that developed the V8 for the 1990s Chevy Corvette ZR-1. That all-aluminum LT-5 under the hood cranked out 405 hp – an astronomical figure for the time – and helped make the ZR-1 an icon. Take a listen to Tantrum's 9.0-liter Mercury mill below.

You might not know: Tantrum won the Best Domestic category of the GT Awards at SEMA – chosen by your author. The sinister looks were the hook, and the crazy engine solidified its performance cred.

25,000 Jeep Grand Cherokee, Dodge Durango SUVs recalled over brake feel

Chrysler has announced that it is recalling over 25,000 Jeep Grand Cherokee and Dodge Durango SUVs from several markets over concerns about brake feel under hard braking. The affected models are from the 2012 and 2013 model years, although the actual dates of production aren't available. 18,700 are in the US, while 825 are in Canada, 530 are in Mexico and a further 5,200 outside of North America.
According to a statement, Chrysler was informed of the issue by a component supplier for the Ready Alert Braking system, which primes the brakes in anticipation of an emergency stop. A component in the system was restricting the flow of brake fluid too much.
As Chrysler is quick to point out, the way the brakes functioned was in compliance with regulations and there are no reported cases of drivers losing braking power. Instead, the issue rests with what Chrysler calls a pedal feel that "was not consistent with customer expectations." So it would seem Chrysler is being proactive and fixing a problem not because there's a legal issue at work, but simply because it doesn't feel the way the manufacturer wants it to. Well done.

Hypermiling a Ram 1500 EcoDiesel to 38.1 mpg

You never quite know what Wayne Gerdes has up his sleeve. The man who coined the term hypermiling is always looking for adventurous ways to prove that anyone – even you... yes, you – can eke out more miles per gallon just by changing the way you drive. Saying that is easy. Proving it by going on outlandish cross-country drives is hard. But for Gerdes and his team of fuel economy fiends over at CleanMPG, hard is half the fun. Our latest adventure appeared, at first glance, to be nearly impossible. Which is why we always answer the phone when Gerdes calls. He likes to take journalists along on his drives, not only to try teach us how to hypermile but also to prove that we can be taught. The first time I 'helped' him and his team was when we got over 30 miles per gallon in a 2011 Ford F-150 XLT with the EcoBoost 3.5-liter V6. The EPA rated that truck with at just 16 mpg in the city and 22 on the highway. So, we'll count that trip as a success. Next up was a cross-country drive last fall in a trio of Audi TDI vehicles to prove that you don't need to drive extra slow to beat the EPA numbers. In fact, we made it from Los Angeles to New York City in just over 46 hours, cramped but not cranky. We had once again proven that how you drive is hugely important to your fuel usage. Our latest adventure appeared, at first glance, to be nearly impossible. The EPA says that the Ram 1500 EcoDiesel we would be driving gets just 22 combined mpg (19 city and 27 highway). Gerdes' idea was to drive it as far north from Houston, TX towards Detroit, MI as we could go on one tank. The day before we left, our itinerary got an extra stop. Instead of taking one of the official Shell Eco-marathon prototype vehicles to Detroit, it was decided to bring the winning diesel-powered prototype from the just-finished event to The Henry Ford Museum, where it had been arranged the car would be displayed. The winning car was built by a small team (just four students) from Sullivan High School in Sullivan, IN, who managed to beat a number of college teams with a score of 1,899.32 mpg. That target would be a bit out of reach for the Ram, but could we get 1,000 miles from the tank? Since the truck has a 26 gallon tank (officially, anyway), that would mean the EPA says we could only go 702 miles, assuming all highway driving. Could we make up 300 miles with careful driving? That spells both challenge and fun.
