An induction-hardened steel crankshaft-secured to the block by twice the usual number of bolts-makes the engine strong and helps to minimize vibration.
These features combine to produce ready horsepower and torque for a quick off-the-line feel and impressive highway passing power.Ĭounter-rotating balance shafts quell the low-speed rumble and high-rpm tremble common to large, powerful four-cylinder engines. The aggressive camshaft profile, with increased valve lift and duration, enhances the engine's ability to "inhale" the fuel mixture and "exhale" spent fumes efficiently. The intake manifold runners are tuned for maximum mid-range response, yet contoured for effectiveness at both low engine speeds and wide open throttle conditions. This cooler, denser air charge helps produce more complete combustion of the fuel mixture and better power. Drawing air from above the radiator, rather than from inside the hot engine compartment, the cold-air induction system allows a cooler, denser charge of air/fuel to be fed to the cylinders. The large displacement and low-speed torque capabilities of the 4G64 minimize this engine's need for high rpm to make power as required in smaller displacement four-cylinder engines.įeatures that contribute to the 2.4-liter engine's responsiveness include torque-savvy cam profiles and an isometric intake manifold with cold-air induction system. The large-for-a-four-cylinder 2.4-liter in-line engine found in the Spyder GS produces 147 horsepower at 5500 rpm (140 horsepower when mated to the automatic transmission) and an impressive 158 pound-feet of torque at 4000 rpm (155 pound-feet with the automatic transmission). This powerplant is tuned to the sporting characteristics of the Spyder and provides ample torque for brisk acceleration from a standing start. The Eclipse Spyder GS shares the responsive 2.4-liter, SOHC, 16-valve four-cylinder engine with its Coupe sibling. Each of the Spyder's engines is designed to deliver superior torque while maintaining good fuel economy and meeting Low Emission Vehicle (LEV) standards. The Eclipse Spyder offers two engine options: a powerful 2.4-liter four cylinder and a spirited 3.0-liter V6.
The combination of bold styling, responsive power and exciting performance made the Mitsubishi Eclipse Spyder convertible an immediate success upon its introduction three years ago.
