• "Did anyone notice that the small block Chevy "pushrod" engine was named Europe's best engine of the year last year?"
• "Yes, it has a twin-turbo pushrod V8, eight-speed transmission, a steering wheel, a windshield, tires."
• "The choice to retain the old-school pushrod V8—with massive Mitsubishi turbochargers snorkeling the thing—instead of a 12-cylinder is plainly a bid for heritage cred, even though this unit is updated with variable cam phasing variable valve timing, if you like and fuel-saving cylinder deactivation."
