The MAZDA5's sole engine is a 2.3-liter DOHC inline four. Known as the L3-VE, this 16-valve engine is part of the MZR family, used by nearly all Mazda passenger cars. All MZR engines are all-aluminum, with an open-deck cylinder block for reduced weight and improved cooling; vibration-quelling counter-rotating balance shafts; chain-driven overhead camshafts; variable intake valve timing; and intake runners optimized for better mid-range performance. The L3-VE engine is undersquare, with a bore of 87.5 mm and a stroke of 94.0 mm, to improve low-speed response. The MAZDA5's version has a compression ratio of 9.7:1, and makes 153 horsepower and 148 lb-ft of torque.
