Chevrolet and General Motors are serious in their plan to overtake leading position on the market from Toyota’s full size pickup Tacoma. With a lot of improvements, such are lighter engines and construction, also direct injection, they get a lot better fuel economy. GM has a plan of a diesel version of the Chevrolet Colorado hitting 30 MPG. If 2015 Toyota Tacoma wants to keep up, they should consider this treat seriously. Current model of Toyota Tacoma EPA mile per gallon is 25. Can we estimate MPG average for 2015 model? We can only guess according to some facts, but we can’t know exact numbers until the unveil of 2015 Toyota Tacoma.
Lets start with engines. Ford’s Eco Boost engine with turbochargers has many fuel saving features. Also, GM has EcoTech3 engines which are made of aluminium. Direct fuel injection and continuously variable valve timing gives better fuel saving and with seamless cylinder deactivation it could shred consumption. We could estimate that all new engine upgrades could save up to 2.5 MPG on fuel economy.
Now we’re moving to transmission. Full size truck transmission changes are own of the hot topics between companies that produces these vehicles. Improving entire powertrain is the largest part of the fuel economy saving. Gearbox should be improved to 8-speed transmission on the way of fuel saves. Toyota is doing great in this area. With improved transmission, we can estimate that 2015 Toyota Tacoma could save up to 2 MPG more.
With all new materials used in making of full size trucks, weight drop is expected, and it should bring saves on the fuel. It is rumored that Ford’s, 2015 model vehicle – F150, could lose 700 pounds on new materials, lighter brakes and axle. It is rumored that the F150 will have fuel economy improved for 3MPG. GMC and Chevrolet are both respected to have similar weight drop, so as fuel consumption rate. The new 2015 Toyota Tacoma won’t have such weight losses, so it can’t be expected same MPG improvements. With all Tacoma’s upgrades, we can estimate an improvement of 1.25 MPG on weight loss.
Another fuel saving area is aerodynamic. GM is a leader in this. Their biggest advancement in aerodynamics is in the Dodge Ram 1500. The vehicle uses grille shutters to improve air flow at optimal times. When it isn’t needed, it is closing off air and all features. Ram 1500 improved its MPG rate from 20 to 25. Better aerodynamics and using of grille shutters, could add 2 MPG to the 2015 Tacoma. But with current improvements we could estimate it will be 1.25 MPG.
At the end, when we calculate all mentioned, we get : 2.5 MPG for the New Engine Technology, + 2 MPG for Transmission, + 1.25 on Weight drop and + 1.25 for Aerodynamics improvement, which gives total of + 7 MPG consumption. Current model of Tacoma (2012 year model, 2WD 4 cyl, 2.7 L, Manual 5-spd, Regular Gasoline) has fuel economy of 25 HW, 21 city and 22 combined. The 2015 and 2016 Tacoma could be at 32 MPG. If Toyota develop them as Hybrid, that could be easily converted to 37 MPG.
