• SmartTruck engineering and design was born in the aerospace, motorsports and automotive industries:– Boeing and NASA Technology– Aerion Super Sonic Business Jet– Boeing MD 80 Winglet for aging aircraft– Racing and Motorsports
• Daytona Prototype development• Indy Car • NASCAR
– Ballistics– Ford Hybrid Concept Car– Bright Automotive Plug-In Hybrid Van
• SmartTruck’s mission: transfer technology and design techniques from the aerospace industry to the trucking industry to produce groundbreaking, rugged performance equipment for tractors and trailers

Fuel Performance Perspective
• 1977 Trans Am compared to now– HP, MPG
1977 Pontiac Trans Am •1978 CAFE std: 18.0 mpg
•Vehicle Specs:– V8 6.6L engine: 200 hp– ~14 mpg
The Car: 1977 to 2014
2014 Chevrolet Camaro•2014 CAFE std: 31.3 mpg
– (74% improvement over 1978)
•Vehicle Specs/Options:– Camaro 1LS
• V6 3.6L engine: 323 hp• 22 mpg (combined)
– Camaro 1SS• V8 6.2L engine: 426 hp• 19 mpg
– Camaro ZL1 (shown in photo)• V8 6.2L Supercharged engine: 580 hp• 14 mpg
The Tractor Trailer: 1977 to 2014
1977 Tractor Trailer Fleet•4.6 mpg (Argonne National Labs)
•Tractor:– No aerodynamic fairings– Exterior air cleaner and exhaust stacks– Square nose
•Trailer:– 48’ Trailer limit
2014 Tractor Trailer Fleet•6.5 mpg (41% improvement over 1977)
•Tractor:– Aggressive aerodynamic improvements
•Trailer:– 53’ Trailer limit

Opportunities for Fuel Savings
% Fuel Efficiency Improvements
Data from multiple sources: NESCCAF, ICCT, Calstart, Navistar
• DOE SuperTruck Program: ~10 mpg– 50% improved Tractor Trailer efficiency (compared to 2009 MY)
• 30/50% improvement achieved through vehicle technologies• 20/50% improvement achieved through engine technologies• Attain 50% engine brake thermal efficiency and demonstrate path to 55%
• EPA/NHTSA FE/GHG Standards: – Phase I (MY 2014 – 2018): ~8 mpg
• ~20% improvement by 2018 (compared to 2010)• Only address tractor and engine system (no trailers)• Also looks at vehicle efficiency: ton-miles/gal or g CO2/ton-mile
– Phase II (TBD): may include trailers
Future Performance Targets
Aerodynamics• Due to the amount of highway miles driven, the tractor trailer would
benefit more than any other vehicle on the road from advanced aerodynamic improvements.

• Testing and validating fuel performance
• Ensuring individual system improvements work with other system improvements
• ROI vs. CapX
• Trailer to tractor ratio: national average is 2.75
• Driver training and capability– Drivers impacts can be 30%
• Vehicle size and longer combination vehicles
