Like the California T, the Portofino is powered by a front-mounted twin-turbocharged 3.9-liter V-8, but with a new intake system, redesigned pistons, revamped connecting rods, an improved exhaust system, and new engine management software. These measures allow the high-revving V-8 to produce an estimated 591 horsepower and 561 lb-ft of torque, gains of 39 horses and 4 lb-ft. Ferrari says the Portofino will make its way from zero to 62 mph in just 3.5 seconds. That may be a conservative claim, considering our test of the California T returned a zero-to-60-mph time of 3.3 seconds. Ferrari says the new model will top out at “over” 199 mph, but doesn’t say how much over. That’s 3 mph better than its claim for the California T.
