The ES 350 is powered by a 3.5-litre V6 petrol engine that is designed to deliver commanding acceleration and a stirring note. This impressively smooth engine benefits from an update to the D4-S fuel injection system and now develops 250 PS/183 kW of torque, marking significant increases on the performance of the previous generation V6 unit.

As well as the boost in power and torque, the ES 350 also gains a new eight-speed Direct Shift automatic transmission. This uses an ultra-thin torque converter and a multi-plate lock-up clutch to transfer power to the front wheels more efficiently. It is tuned to deliver crisp, precisely timed shifts with quick pedal responses. With a wider spread of rations, it can us high-torque gears at the low end for quick starts, and tall gearing at the high end of optimum efficiency.

High-speed combustion is a core element of the new engine’s ability to provide the most efficient use of fuel. To achieve this, the cylinder bores have been narrowed slightly (90mm to 87.5mm) and the stoke lengthened (98mm to 103.4mm) to create an optimal 1:1.2 bore-to-stoke ratio as well as reducing the distance the fuel must travel to reach the edges of the cylinder. The angle between the valves was also increased to create a more direct path for the incoming air while the intake valve seats use a laser cladding process that allows for a larger valve seat area, reduced seat face temperatures and a smoother transition from the intake port to the combustion chamber. The result is an optimized swirl pattern and the ability to run more ignition advance in lean conditions without approaching knock limits.
