Airflow Starship - High-Mileage Fuel-Efficient Truck
The Starship Initiative is an innovative, material step towards reducing emissions and increasing overall efficiency and fuel economy in the transport sector. This next-generation truck features a custom, aerodynamic design and aims to demonstrate improvements in fuel economy for class 8 trucks while lowering CO2 emissions.

The Next Innovation
The pursuit of significant fuel economy gains for class 8 trucks and trailers is a challenging process given the size and traditional construction of a tractor and trailer. However, with new fuel economy regulations on the horizon and the need for continuing advances in fuel economy, Shell Lubricants recognizes that a holistic approach to making fuel economy gains is important.
Shell Lubricants and AirFlow Truck Company joined forces to develop a hyper-fuel-efficient Class 8 tractor trailer, the Starship Initiative—and sent it coast-to-coast to see what kind of efficiency improvements could be made to the transporting of goods by road.
Making an Impact
If all trucks in the U.S. reached the overall fuel economy and freight ton efficiency performance of Starship, CO2 emissions from the U.S. truck fleet would be reduced by 60 percent.
What We Did
The Starship Initiative truck completed a test run of more than 2,300 miles across the United States. This journey marked the first time that a prototype Class 8 vehicle of this type with these combined technologies had driven coast-to-coast [Hyperlink to .pdf entitled NSR01124-Starship Journey Map_11in x 8pt5in FO] across America in real-world trucking operations and in real-world conditions including unplanned stops and torrential rains along the way.
The final total truck and cargo weight was close to 73,000 pounds, which is 28 percent heavier than the average total gross vehicle weight of 57,000[1] pounds for a U.S. on-highway Class 8 truck. The payload weighed in at 39,900 pounds, 77 percent more mass than the U.S. average payload of 22,500[2] pounds, and was comprised of clean reef material destined for a new offshore reef installation in Florida.
The Results
Despite far-from-perfect road and weather conditions, the drive itself was a success. Starship attained 178.4 ton-miles per gallon, nearly a 2.5 times improvement over the North America average freight ton efficiency of 72 ton-miles per gallon for trucks.
Freight ton efficiency is a more relevant statistic than miles per gallon for on-road transportation of goods because it combines the weight of the cargo being moved with the amount of fuel consumed.
For the entire journey, which included vastly different road, weather and terrain conditions, the Starship truck’s total average fuel economy was 8.94 miles per gallon, compared to the average U.S. fuel economy for transport trucks at 6.4[3] miles per gallons. The best fuel economy attained during the drive was 10.2 miles per gallon.
If all trucks in the U.S., 2 million of them, reached the overall fuel economy and freight ton efficiency performance of the Starship initiative truck, they would emit an estimated 229 million less tons of CO2 into the atmosphere per year. This would correspond to a huge, 60 percent, reduction in CO2 emissions from the U.S. truck fleet, highlighting the benefit of the enhanced economy and increased loading strategy adopted within the Starship Initiative.
Our Work Isn’t Finished
We are proud of the results of our first test run of the Starship Initiative truck. However, we feel there is more work to be done and the dialogue and the learning must continue. Check back in with us to see where we go from here. Join the conversation with #ShellStarship

[Dialogue]
{Enter Bob Sliwa}
{Creator of the The Starship Truck}
{In my generation, all the guys at 15 and 16 years old were just enamored with cars. The brute force of a muscle car, the acceleration, the G-force, the power. I can remember as a teenager, having a very important race coming up at the drag strip, working literally a 20 hour day. I was dog tired, but it was the nicest feeling of being extremely tired that one could ever imagine, because there was such an amount of achievement that we did in that 20 hours to get the car ready for the race. That is directly analogous to what we do today.}
[Animated Video Sequence]
The Starship Initiative Logo animation appears over the grill of the truck. Close-ups of the Starship truck and Bob working on the truck.
[Dialogue]
{Bob Sliwa}
{The number one goal is to get the best freight ton efficiency. You want to move several tons of freight, the most we can move on one gallon of fuel. We spent 18,000 hours to put just a tractor together. Anything that you can do to a race car to make it go faster, we've done that to this truck to save fuel. If you can improve efficiency of a truck just a little bit, you're going to help the ecology, lower emissions, and you're going to get a lot better fuel-mileage. I'm extremely grateful to Shell that has given me the opportunity of a lifetime. I couldn't have done this without them.}
[Dialogue]
{Enter Chris Guerrero}
{Shell Lubricants, Global HDDEO Brand Manager}
{When the idea first surfaced, it was really born of an exploration into this area around fuel economy. There was a story that stood out to us, and it was really the story of Bob Sliwa. We saw him make a big impact and we thought this is someone we can work with, because he has passion in this space.}

{Shell Lubricants, Global HDDEO Brand Manager}
{All right, let's do it. The goal of the trip is to measure freight-ton efficiency.}
[Dialogue]
{Enter Dan Arcy}
{Shell Global Solutions, Global OEM Technical Manager}
{How much energy is it going to take to move a certain amount of freight from point A to point B?}
[Dialogue]
{Megan Pino}
{We don't have a specific number we're reaching for, we really just want to see how good we can be.}
[Dialogue]
{Chris Guerrero}
{One thing that is probably the most underestimated contributor to fuel economy performance is the driver. And it's Bob Sliwa for us. It's the role that he plays in maximizing the delivery of that truck in terms of fuel economy.}

{The journey we're going to do on a transcontinental run will be from San Diego, California to Jacksonville, Florida. I travel with my constant companion, my 12 German Shepherd dog, Kayla. Kayla and I are inseparable, we're together 24 hours a day. And we're just buddies. She's my buddy, everybody needs a dog so they have a little bit less stress.}
[Dialogue on-screen]
{Megan Pino}
{We're ready to load in with reef material for the Coastal Conservation Association.}
[Dialogue]
{Bob Sliwa}
{It's as real-world as it gets, and we only feel that adds to what the kids call "street cred." That's how we do it. That's a safe load.}
[Dialogue]
{Megan Pino}
{What's interesting about a demonstration vehicle is that little things can go wrong that you wouldn't expect.}
[Dialogue]
{Bob Sliwa}
{The operational challenges, and there's obviously mountains between here and Arizona. I'm nervous that we've got a pretty tight schedule. No pressure for me. Right? We just have to get the best hopefully fuel-mileage and freight-ton efficiency in the world.
[Video sequence]

[Dialogue]
{Bob Sliwa}
{The country is wildly dependent on trucking and transportation, for everything. Anything you buy, the piece of paper in your hand, the cameras that we're using for photography, food every day in the store, any of the things you get, comes over the road on a highway in a big truck. If somebody pulls next to me with a traditional truck with a 600 horsepower motor, if I did want to race them, I would probably beat them and make them cry. There's so little holding this truck back. This truck is theoretically geared to do 114.5 miles an hour. We wouldn't go that fast, obviously, but that just means that we can run it at extremely low RPM and the engine would be so down-sped, we're going to save a lot of fuel that way.}

{We put 5000 watts of solar panels that generate electricity on top of the trailer. We support a full carbon fiber cab, aerodynamic side-skirting along the tractor and the trailer, and all the way back to the boat tail, managing the air that's coming off the back of the truck.}
[Dialogue]
{Chris Guerrero}
{It is the combination of all those parts that allows this truck to do what we want it to do.}

[Dialogue]
{Megan Pino}
{We've had a lot of interactions with truckers today. We're really providing them with some education, talking about the technology that we've built onto the Starship truck. This has been a great opportunity to just start that conversation with truckers around efficiency improvements in their own truck, in order to lower CO2 emissions.}

Super: Mile 2,410
[Dialogue]
{Bob Sliwa}
{39,000 pounds, that's a pretty gosh dang good load of freight. The brochures they've seen, the images, the pamphlets, even the video, doesn't really hold a candle to seeing the truck in person. They're just awestruck, and they can see the physicality of the truck. I think we're about two-thirds of the way. We've got a couple days left, and thank God. Arduous out there on the road sometimes. Right now, we're in 18th gear. We're doing 59 miles an hour, my feet are flat on the floor. We're only doing 914 RPM. So it's very quiet, you can't even hear the engine, you can just hear the tires. 5.8 miles, exit 343. Okay here we are at about 10 minutes after 6, through the evening, in Jacksonville.}
[Dialogue]
{Megan Pino}
{We made it! How do you feel? We finally made it! I'm fighting back tears, honestly. Just joy, excitement}
[Dialogue]
{Chris Guerrero}
{So here is to the vision and patience and perseverance, most of all, of Bob Sliwa. Congratulations on the run. Cheers. What an amazing feeling. A labor of love just means you finally got to the point where something really, really special has arrived. But now we have a responsibility to make sure it becomes even more than what it is today.}

The Team Behind the Truck
Robert Sliwa – Owner – Airflow Truck Company
After six years of regional trucking, Robert ‘Bob’ Sliwa opened his own over-the-road trucking company. After realizing how inefficient long-haul trucks were, (he could only average 4.4 mpg) Bob began modifying his cabover and tweaking one thing at a time until he reached 10 mpg.
He began work on a second super-aerodynamic and hyper fuel-efficient Class 8 rig, the BulletTruck, in 2009. He introduced it to the public and began weekly “real-world” freight hauling runs with it in 2012.
And for the last few years, Bob has been designing and building Starship with a small crew in New Britain, Connecticut.

Bob Mainwairing – Technology and Innovation Manager, Shell Lubricants
Bob is a mechanical engineer and leads Shell’s global automotive engine and lubricant research team for Starship.
Bob leads many co-engineering projects for Shell including the Shell Concept Car, an urban vehicle that uses less energy than other cars available today. The Shell Concept Car sought to explore the role that lightweighting, streamlining and lubrication played in personal transport, much like the Starship Initiative which explores the equivalent for freight transport.
