Mercedes-AMG GT vs. Porsche 911 [w/poll]

Mercedes-Benz designed the AMG GT to compete head-on with the Porsche 911. It's a clear, singular purpose, and Benz brings a lot of money, technology and race-bred expertise to the fight.
The AMG GT is Merc's followup to the awesome SLS AMG, the retro-modern, gullwing-doored coupe that took us by storm half a decade ago. But this new GT coupe is a more focused sports car than the SLS, rather than an all out supercar capable of extreme performance. It's got a brand-new V8 engine, and state-of-the-art technology that help it to not only be a proper Mercedes, but to be a serious performer.
Mercedes will sell its new baby in two models. The GT S arrives first, in spring 2015, followed by the standard GT in mid-2016. Of course, there's room to grow from there. And while Porsche may have already expanded its 911 range to include a vast variety of models, here's how Stuttgart's icon stacks up against Affalterbach's bad boy.

2017 Porsche Macan receives delayed CARB certification

Customers waiting for delivery of their 2017 Porsche Macans will soon receive their vehicles after several weeks of delays. The California Air Resources Board certified the performance crossover for sale Monday. Several outlets reported the certification had been held up in the aftermath of parent company Volkswagen's diesel woes, as regulators are now making much more thorough inspections of the vehicles. Without certification, Porsche could not deliver those vehicles to customers in 13 states that abide by CARB certification, including California, New York, Pennsylvania, and Florida, several of the largest markets for luxury automobiles in America. Not only did dealers need to stop sale of Macans they had on their lots, but an unknown number could not be released from port. Porsche Cars North America (PCNA) imports its vehicles through ports in Jacksonville, FL, Davisville, RI, Houston, TX, and San Diego, CA. A spokesman for Porsche told Autoblog the issue has been resolved, and that the Macans received certification Monday. "Shipping has already been initialized," spokesperson David Burkhalter wrote. Pressed for details on the circumstances behind the delay, he said the process was simply "now the normal business procedure for certification." The Macan is a pivotal model for Porsche, particularly in the US market, which accounts for 22 percent of its worldwide sales. Last year, the Macan was the second-best selling Porsche model in America. Its 13,533 units sold trailed only the 16,473 Cayennes purchased by US buyers. Diesel models of the Cayenne manufactured between 2013 and 2016 contained the defeat devices at the center of Volkswagen's emissions cheating, according to the Environmental Protection Agency. The company offers the Macan with a range of turbocharged six-cylinder engines ranging in output from 340 to 400 horsepower. While a diesel version is not offered in the United States, Porsche has now started importing a less powerful, but more accessible (and slightly more fuel-efficient) version with a 2.0-liter turbo four.
