1. Good Jobs Green Jobs Conference Washington DC 2/10/2013 SmartTruck Systems A Look at Tractor Trailer Fuel Efficiency

2. 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 SmartTruck Introduction

3. SmartTruck’s focus is on advanced aerodynamics

6. 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

7. 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

Moving Forward

9. Opportunities for Fuel Savings % Fuel Efficiency Improvements Data from multiple sources: NESCCAF, ICCT, Calstart, Navistar

10. 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 CO 2 /ton-mile – Phase II (TBD): may include trailers Future Performance Targets

11. 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.
