After months of speculation and spy shots, Maranello has finallyrevealed the mid-engined V8 replacement for the Ferrari F430. Theall-new Ferrari 458 Italia won't be shown in public until September's Frankfurt Motor Show,but the official details were released early this morning. A newdirect-injected 4.5-liter V8 ups the ante underhood, pumping out 562horsepower and 398 lb-ft of torque. The redline? A screaming 9,000 rpm.Eighty percent of the F458 Italia's torque is now available at a low3,250 rpm, thanks in all likelihood to the new engine's 12.5:1compression ratio.
As with last year's California, the Ferrari458 gets a seven-speed dual clutch gearbox that directs power to therear axle. Much has been done to reduce internal friction within thenew V8, in addition aerodynamic drag improvements. As a result, theFerrari 458 Italia's gas mileage improves to a combined 17.1 mpg (US)on the EU test cycle. As this is a Ferrari, talk of fuel consumptionreally does seem somewhat pointless, anyway. No mention ofincorporating any type of KERS hybrid system has been made thus far.The KERS idea, you'll remember, had taken several spins around therumormill over the last year or so; maybe that'll materialize at alater date.
Like its predecessor, the Ferrari 458 Italia'saluminum structure helps keep weight under control -- it tips thescales at just 3,042 pounds dry. So, we know you're wondering: Howquick is it? Based on specs at least, this new coupe does't disappoint.Acceleration to 100 km/h (62 mph) takes just 3.4 seconds, and this willbe the first volume production Ferrari V8 to top the 200 mph barrier,with a top whack of 202 mph. Is it still too early to head to theairport for our flight to Frankfurt in September?
