The heart of the 2019 Ford Mustang Shelby GT350 continues to be a 5.2-liter flat-plane crank V-8 producing 526 hp and 429 lb-ft of torque, paired to a Tremec six-speed manual transmission. In our 2016 review, we recorded a 0-60 time of 4.1 seconds and a figure-eight performance of 24.2 seconds at an average 0.82 g. We'll report back once we've had a chance to see if the updates made for 2019 allow us to improve upon these figures.
