How Ferrari was able to keep their new toy under wraps for so long, we may never know, but all that matters now is that their 670-hp 488 GTB is officially here. Presenting more than just a visual make-over, the GTB - formerly known as the 458 M - is the latest prancing horse to boast a turbocharger, among a range of updates. Right off the top, there's now a twin-turbocharged 3.9-liter V8 engine putting out enough muscle to send it to 62mph in 3 seconds, 124mph in 8.3, and a top speed of 205 mph. All that power is controlled through a new seven-speed dual-clutch transmission with variable torque management and custom gear ratios. Visually, a large air intake scallop is a nod to the originals 308 GTB while the wider front spoiler and new diffuser are also very noticeable. Inside the supercar, the cabin should be familiar to the Ferrari faithful save for the addition of satellite control clusters and a refined instrument panel and infotainment system. Oh, and to top it all off, Ferrari promises the 488 GTB's exhaust has been tuned to "deliver a full, clear, and totally distinctive soundtrack."
