The newer Toyota Highlander's now come with an eight-speed automatic transmission, as well as 295 horsepower, in addition to the 3.5 L V6 engine displacement. They are the best in both worlds. The all-new, 2024 Toyota Grand Highlander HybridMAX comes with a 2.4 L turbocharged four-cylinder engine, which produces 362 horsepower and the six-speed automatic transmission. The Grand Highlander is much better and much safer than the regular one. Thanks.
