Exterior design changes made to the refreshed 2014 Toyota Tundra can help you bring full-size pickup buyers to the Toyota brand, but with only carryover engines, the model is at somewhat of an obstacle against trucks with newer drivetrains. With updated engine options, the 2014 Tundra may be rather more than simply a cosmetic refresh. But what drivetrains should power Toyota’s full-size truck In preference to choosing practical, real-world options, we let our imaginations run wild. Listed here are some of our picks below.

• Diesel Hybrid Setup From Hino Box Truck: Many forget that Toyota has parts from its commercial truck subsidiary Hino at its disposal. One drivetrain specifically that may benefit the Tundra is the company’s diesel-electric hybrid system. That utilizes a 210-hp, 440-lb-ft turbodiesel I-4 paired with an electrical traction motor generating 48 hp and 258-lb-ft of torque. Considering Toyota’s experience and history with hybrids, an electrified Tundra might make sense for the logo. A diesel Tundra may also become the workhorse of the lineup.
• Lexus IS F 5.0-Liter V-8: A high-performance version will not be what the Tundra needs for fulfillment, nonetheless it will be pretty cool. The high-revving, naturally aspired 5.0-liter V-8 out of the Lexus IS F can make for one fast pickup, with its output of 416 hp and 371 lb-ft. The sort of truck may be positioned against the Ford F-150 SVT Raptor, or tuned for on-road performance just like the Jeep Grand Cherokee SRT8.
• Lexus LFA V-10: Though it won’t have a ten-cylinder Ram SRT10 to compete with, a Tundra packing the Lexus LFA’s 552-hp, 354-lb-ft 4.8-liter V-10 would probably be absurdly fun. With the LFA now out of production, Toyota has a worldwide-class sports car engine design just begging for a brand new home. Why not make it the Tundra
• NASCAR V-8: Another entry within the “why not” category, the Tundra race truck’s 5.9-liter pushrod V-8 utilized in the NASCAR truck series may be used as a basis for a production version. Granted, the carburetor and other non-road-legal parts would need to go, but adapting a race engine design for street use wouldn’t be impossible. TRD dropped such an engine right into a Camry many years back for the 2010 SEMA Show. If any NASCAR-powered Toyota model has a shot at production, though, it’s the Tundra.
