Maserati will inject a little more performance into its stylish Jason Castriota-penned GranTurismo range next month at the Geneva Motor Show when it unveils its latest GranTurismo Sport coupe, which will replace the GranTurismo S in North America. Subtle body changes to the front bumper encourage airflow to a more powerful 460-horsepower version of the GranTurismo’s 4.7-liter engine. As a result of the power increase, the 0-60 mph sprint will take less than 5 seconds and the coupe can top out at a blistering 177 mph. With a completely reworked lighting system on both the front and back, as well as a new interior, the GranTurismo Sport is but a shell of its former self. Look for more details to emerge as the official March release date creeps ever closer.
