Callaway debuts its new C7 Stingray at National Corvette Museum

Callaway showed off its first tuned version of the 2014 Corvette Stingray at the National Corvette Museum last week, giving the rampant enthusiasts of America's sports car a look at the roughly 620-horsepower, supercharged rocket.
Unlike the Corvette SC610 we showed you back in January, this Stingray packs a fair bit more oomph. Horsepower is only up ten ponies, but torque has jumped from 556 pound-feet to "at least" 600 pound-feet. Neither horsepower nor torque is official quite yet, although Callaway is expecting to know just what its creation can do once testing and validation is completed later this month.
The 6.2-liter, supercharged V8 now boasts a new, three-element intercooler, which Callaway claims only allowed the inlet air temperature to increase by ten degrees Fahrenheit during dyno runs. Previous designs saw a 35-degree-Fahrenheit jump. The exhaust system has also been fettled with, and now is even less restrictive.

Common Dodge Ram 1500 vs. Chevrolet Silverado breakdowns

These two trucks are famous for their ability to get the job done. Still, even the toughest vehicle can have mechanical problems at some time. What if we match the Dodge Ram 1500 and Chevrolet Silverado head to head? Let's find out more about common repairs for each model. Also, learn some tricks to pay for car repairs. Clunky Steering Both Dodge and the Chevy owners sometimes notice bumping and clunking when steering. This might be more noticeable when driving over bumps. The cause is usually different in each truck though. In the Dodge Ram, clunky steering is more likely due to a defective lower ball joint. Replacement costs around $300 - $400, parts and labor. Clunky Chevy Silverado steering is probably a steering rack failure. This problem appears more often in trucks with over 90,000 miles. Silverado steering rack repair will run you up to $1,000 or more. Starting Woes For the Chevy Silverado with over 130,000 miles, you might notice trouble starting. This problem may appear occasionally at first, but it typically gets worse. Excluding a weak battery, the culprit is usually the starter. Replacement will cost you around $330 - $500. Of the total cost, $90 is for labor only. Now the Dodge Ram might make a ticking sound when starting, especially on models with over 94,500 miles. The noise often disappears after the engine warms up. These symptoms may indicate a broken exhaust manifold. Repair costs range from $800 - $900. Burning Oil & Gas Gauge On The Blink Sometimes, the Dodge Ram burns oil much faster than normal. In models with over 125,000 miles, this often points towards a leaky intake manifold gasket. A knocking sound may also appear with acceleration along with possible engine misfire. The cost to repair is around $200 - $300. The Chevy Silverado has its own surprises, especially when you've filled the gas tank but the gauge still reads low. Or the needle fluctuates widely from low to full while driving. In trucks with over 120,000 miles, it's likely due to a faulty fuel sensor. You might need a full fuel pump replacement, which can cost you up to $820, parts and labor. Water Inside And Poor Heat The Ram 1500 rear window has been known to leak. You might notice the back seat and floor wet after a rainstorm. This is more common in trucks with over 65,000 miles. Resealing the Ram 1500 rear window costs around $150 - $250.

Autoblog's guilty pleasure cars

Guilty pleasures are part of life – don't even try to pretend like you don't have one (or two, or six). In the non-automotive space, this could come down to that secret playlist in your iPhone of songs you'll only listen to when you're alone; or think of that one TV show you really do love, but won't admit to your friends. I've got plenty, and so do you. Going back to cars, here's a particularly juicy one for me: several years ago, I had a mad crush on the very last iteration of the Cadillac DTS. Oh yes, the front-wheel-drive, Northstar V8-powered sofa-on-wheels that was the last remaining shred of the elderly-swooning days of Cadillac's past. Every time I had the chance to drive one, I was secretly giddy. Don't hate me, okay? These days, the DTS is gone, but I've still got a mess of other cars that hold a special place in my heart. And in the spirit of camaraderie, I've asked my other Autoblog editors to tell me some of their guilty pleasure cars, as well – Seyth Miersma, as you can see above, has a few choice emotions to share about the Mitsubishi Lancer Evolution. Read on to find out what cars make us secretly happy. Mercedes-Benz SL65 AMG This decadent convertible is the epitome of the guilty pleasure. It's big, powerful, fairly heavy and it's richly appointed inside and out. It's a chocolate eclair with the three-pointed star on the hood. Given my druthers, I'd take the SL65 AMG, which delivers 621 horsepower and 738 pound-feet of torque. That output is borderline absurd for this laid-back convertible. I don't care. You don't need dessert. Sometimes you just crave it. The SL line is about the feel you get on the road. The roof is open. The air, sun and engine sounds all embrace you. It's the same dynamic you could have experienced in a Mercedes a century ago, yet the SL gives you the most modern of luxuries. An Airscarf feature that warms my neck and shoulders through a vent embedded in the seat? Yes, please. Sure, it's an old-guy car. Mr. Burns and Lord Grantham are probably too young and hip for an SL65. I don't care. This is my guilty pleasure. Release the hounds. – Greg Migliore Senior Editor Ford Flex I drove my first Flex in 2009 when my mother let me borrow hers for the summer while I was away at college. The incredibly spacious interior made moving twice that summer a breeze, and the 200-mile trips up north were quite comfortable.
