Three Ways Toyota Could’ve Boosted the 2016 Tacoma’s MPG
The all-new 2016 Toyota Tacoma V6 and the mostly new four-cylinder truck are competitive with the gasoline powered Chevy Colorado and GMC Canyon mid-size trucks when it comes to fuel economy. The EPA estimates the 4WD V6 automatic Tacoma returns 20 MPG combined, 18 City, and 23 Highway. The Colorado has similar numbers and the same combined rating. The Duramax Turbo Diesel is only rated at 23 MPG combined, just 3 MPG better. Could the Tacoma match that if Toyota wanted to?

Tacoma MPG Improvement Area - Transmission
When the Tacoma entered its new model year, it received a new six-speed automatic transmission to augment the new 3.5-liter V6 engine. Six speeds are more than enough for comfort and fuel economy, but more gears do help. Rather than go to an eight-speed like the Lexus RX, or even 10-speed like the new Lexus LC 500, Toyota could have gone with a CVT to maximize the fuel economy gains of a broader gear ratio. We are not advocating Toyota does this because the feeling is not the same as a geared transmission. But if maximum fuel economy from an existing gasoline powered, non-hybrid drivetrain is the goal, this is the easiest change and the biggest bang for the buck.
Tacoma MPG Improvement Area – Electric Steering
The Chevy Colorado and GMC Canyon already switched to electric power steering (some call it electronic). By eliminating the hydraulic pump driven off the engine’s accessory belt, and by only using power when moving, electric power steering is a proven fuel saver. Toyota opted to stick with the hydraulic system for this generation to keep steering feel optimal and we applaud that. However, many popular models now have the best of both worlds and automakers are figuring out how to engineer a responsive electric steering system with great feedback. There is also the added bonus of never having to pay for power steering fluid changes. This one is a no-brainer.
Tacoma MPG Improvement Area- Lighten Up
When we first tested the TRD Off-Road I popped and lifted the hood and was shocked by how heavy it was. Our Toyota contact confirms there is a lot of steel in that hood. Tough trucks like the Silverado and Ford F-150 have used aluminum hoods now for generations. Aluminum is a great option, but non-metallic materials may be even better for a hood since it does not have much of a structural or crash responsibility. While we are on the subject of aluminum, Toyota could do the opposite of what Ford did and make its frame out of aluminum. Done right, the frame would be lighter, saving fuel, and also end Tacoma’s vexing frame rot legacy for good.
These three ways to save fuel were all possible on the 2016 Tacoma, and Toyota left them on the table for the next generation to improve on fuel economy. Other corporate average fuel economy credits from things like stop-start are also still open to the Tacoma, meaning the truck still has a way to go before it is at its peak fuel economy. That peak may well be better than 23 MPG in a V-6-powered 4WD truck. So now that you know all this, would you have wanted these changes or not?
