General Motors has developed a new engine - the Chevrolet ZZ632/1000. This is the most powerful gasoline unit for passenger cars in the history of the Chevrolet brand, developing 1004 hp. and 1188 Nm of torque.
The novelty belongs to the Big Block family with a V-shaped configuration of 8 cylinders and is not intended for original equipment of cars, this is the so-called crate engine, “engine in a box”, i.e. it is planned to be shipped only to the secondary market - for use in individual tuning projects or track cars.
632 in the index is an indication of the displacement in cubic inches, in terms of liters it is 10.35 liters (that is, the volume of each cylinder is more than a liter). The manufacturer emphasizes that the intake and exhaust ports for each cylinder of the ZZ632 have the same cross-sections, unlike other Big Block motors, in which they differ from cylinder to cylinder. In addition, the ZZ632 is equipped with individual nozzles - this increases the performance of the motor. Maximum power is reached at 6600 rpm.
The block casting of the ZZ632 is the same as the 9.4-liter ZZ572 that debuted on the track version of the Camaro sports car this summer. However, the cylinder diameter of the ZZ632 is larger (machining is different).
The production of the new motor will start in 2022, the price has not yet been announced.
