The LeSabre Estate Wagon came standard with the larger 325-horsepower 401 V8 from the Wildcat and Electra 225 models. Replacing the old Dynaflow-based two-speed automatic transmission were two new Super Turbine automatics. The two-speed Super Turbine 300 (shared with the intermediate-sized cars) was available with the standard two-barrel 300 V8 while the three-speed Super Turbine 400 (shared with other big Buicks and Rivieras) was standard with the 300 four-barrel and optional with the standard engine as well as the 401 in the Estate Wagon.
