Nissan's heightening its presence on the royal grounds of Britain's (jolly) Goodwood Festival of Speed this year, unveiling a couple of juiced-up concept cars based on two current models. The Murano GT-C (pictured) will be powered by a 350 ps (345 hp) twin-turbocharged 3.5-liter V6 โ€” worked up by the company's tech center in Bedfordshire โ€” and be delightfully outfitted with some yet-unnamed interior and exterior tweaks. Headlining the event, however, will be Nissan's 380 ps (374 hp) supercharged 350Z GT-S concept. That car will also get better brakes and suspension, a body kit and 18" wheels. Nissan says it could build the cars "if the press and the public approve." Isn't that sweet of them?
