With a turbocharger bolted to it, the 2.5-liter four-pot engine in the Grand Touring produces up to 250 hp and 320 lb-ft of torque when running on premium gas. This brings the 0-60 mph time close to six seconds and allows you to fully exploit the brilliant chassis. The addition of paddle shifters behind the steering wheel is another hint at the performance potential. In turbocharged guise, you definitely want more control. Mazda also includes auto-dimming side and rearview mirrors, wireless Apple CarPlay, and an 11-speaker Bose sound system at this level.
