Enter the 2016 Infiniti Q50S Red Sport 400. It’s the version we recently got to sample, and that three-digit number at the end of the name relates to the amount of horsepower the engine is cranking out. It comes by way of the twin-turbocharged 3.0-liter V6 engine. The VQ is gone so say hello to the new VR Series of engines. You might miss some of the old noise but the new power levels and they way in which it’s all delivered is great. This Q50 marks a return to the fun-to-drive G sedan and coupe we remember. It’s eager to spin its tires, get sideways, and have plenty of fun. Here we get a First Drive taste of the car, stand by for a longer review in the coming weeks. [Disclaimer: Infiniti wanted me to check out the new Red Sport 400, so it flew me to San Antonio and put me up in a hotel that used to be an old brewery. Food and drinks were had on the Infiniti dime as well.]
