Mazda is prepping its own entry for the Subie-Mitsu rally wars—a 276-hp, 265-lb-ft Mazda 6 scheduled for a mid-2005 world debut. Spotted during hot-weather tests in the California desert, this sizzling prototype gets a twin-turbocharged and intercooled 2.3-liter four that is mated to a six-speed manual gearbox and sends power via all-wheel drive to 18-inch tires.
