Indications of 825 hp and emissions issues for Hellcat called 'speculation' by Chrysler

The 2015 Dodge Challenger SRT Hellcat is probably one of the hottest cars of the moment mostly because of its insane, 707-horsepower supercharged V8. However, there are conflicting reports coming out that the powerplant might be having problems with its emissions compliance and may be capable of even more power.
Jalopnik says that an unnamed source within Fiat Chrysler Automobiles told it that the Hellcat was having problems meeting emissions standards at its 707-horsepower tune. The person claimed that the automaker has been testing the V8 with different types of sensors, possibly to make it a bit cleaner in the future. Autoblog spoke to SRT spokesperson Dan Reid, and he said about the claimed poor emissions, "It's totally speculation."
The source also claimed that the Hellcat had been dynoed at a monumental 825 horsepower, internally. Based on the other rumor, though, it's hard to imagine the engine being emissions compliant like that. Autoblog also asked Reid about this speculation about more power and was told, "They are totally speculating about that."

Dodge Dart falls short of Consumer Reports Recommended, Caddy XTS and Lincoln MKS, too

The Dodge Dart, Cadillac XTS and Lincoln MKS all failed to earn a "Recommended" rating from Consumer Reports. When it came to the compact Dart, the organization's testers thought the vehicle offered a quiet cabin, solid-feeling chassis and nimble suspension, but the new model ultimately fell short of the coveted rating due to powertrain issues. The institute's reviewers found the base 2.0-liter four-cylinder engine to be underpowered and noted "drivability issues" when the available turbocharged 1.4-liter four was paired with the optional dual-clutch transmission (some of our editors disliked it paired with the six-speed manual). CR also dinged the latter powerplant for sounding "raspy." For what it's worth, we think the forced-induction engine offers an excellent and playful exhaust note, but that's just us.
As for the XTS, CR lauded the car for its luxurious cabin, but the vehicle's experience was dulled by its finicky CUE infotainment interface. Overall, the big Cadillac scored much higher than its cross-town rival from Lincoln. While testers found the American luxury sedan to offer a quiet ride and quality fit and finish, they felt the MKS delivered a "cramped driving position, ungainly handling, uncomposed ride, and limited visibility." Ouch. At the end of the day, both cars fell short of rivals from Japan, Germany and Korea. Check out the full press release below with more details, along with CR's musings on the Chevrolet Spark and Lexus ES.

Chop the top of your new Dodge Viper for $35,000

We have good news, and we have bad news. First, the good: It's now possible to get a brand-new Dodge Viper roadster, which is nice, considering we're in the dead of summer and many of us like wind-in-the-hair motoring. Now, the bad: This is not a factory option from the automaker, instead coming courtesy of an aftermarket company called Prefix Performance, and that means it's going to cost you some serious coin.
Called Medusa, this drop-top Viper was created without the knowledge or consent of Dodge, but that's probably fine because Prefix works with the automaker already for the final preparation of the American supercar, including paint. According to the company, the current, fifth-gen Viper was built with a convertible version in mind, so no chassis strengthening is required. From the looks of the somewhat grainy photos available, the conversion appears of very high quality.
Want one? Well, that means you're going to need to procure a Viper - Prefix has 10 units ready for transformation as it stands - and that's going to cost at the very least $102,485. Then, you'll need to write a check for an additional $35,000 for Prefix to surgically remove the car's roof. Thing is, for that kind of cash, a prospective owner could buy, among other very nice options, a Viper hardtop and a loaded Miata, or a Corvette Stingray convertible and several pockets full of change. Or, perhaps a new Viper hardtop and a used, first-gen Viper convertible?
