the first one was delivered on march 24 , 2015 and the second will be delivered on march 30 , 2015. the company responded on march 6 to a request for information and prequalification ( rfi ) from the united states postal service ( usps ) for its next generation delivery vehicle ( ngdv ) acquisition program . the usps anticipates making a single award in 2017 to a supplier for up to 180,000 ngdvs to replace its current fleet of mail delivery vehicles . delivery of the ngdvs to the usps is expected to begin no later than january 2018. the usps has stated that it expects to evaluate the submitted rfis and announce a short list of oems in april , who will then submit detailed specifications and build several prototypes for testing . there is no guarantee that the company will be invited to submit detailed specifications or , if it is invited , that the company will be awarded as the supplier . the company expects that it is competing against larger , better financed competitors . we recently announced that we filed a provisional patent for a new system that extends the range of electric vehicles while reducing the overall cost of the typical battery-electric power train . the new system , e-gen drive ( tm ) , is designed specifically for the package delivery vehicle market , in which the diesel and or gasoline-powered vehicles in use now , stop and restart hundreds of times a day . we believe that battery-electric technology is an ideal fit for urban and suburban delivery routes and we understand fleet owner 's concerns about range anxiety and cost . our e-gen drive system will enable them to complete the typical route on all electric power using smaller battery packs , thus reducing the cost of the entire system . our e-gen drive trucks , offer a three-year payback making them price competitive with gasoline-powered trucks . our e-gen has recently been approved by the environmental protection agency for on-road use . we believe this is a very significant step towards adoption of this power train by fleet operators . 24 our association with power solutions international ( psix : nasdaq ) provides us with multi-fuel engines that function as generators . when the ignition is shut off , the engine automatically turns on and recharges the battery pack . when the ignition is turned back on , the engine turns off and the vehicle reverts to all-electric power . the engine and the battery-powered motor are never in use at the same time . it 's not a traditional hybrid , but an emergency-range electric vehicle . as a result , we believe our new design has many benefits , including : · fleet management flexibility : depending on our customer 's driving patterns and fuel cost goals , our e-gen drive train can be remotely adjusted to use more electric power or internal combustion engine ( ice ) power at their choice . · energy efficiency and cost of ownership : we believe our trucks offer our customers an attractive cost of ownership profile when compared to similar products . using a single electric powertrain with a small ice enables us to create a lighter , more energy efficient vehicle that is mechanically simple . since we are able to use smaller battery packs , we can reduce the cost of the entire system . additionally , government incentives can reduce the cost of ownership even further . · high performance : we believe our trucks deliver an unparalleled driving experience with powerful acceleration for the most demanding applications with the added benefit of a very quiet operation . we also announced the second generation , full-electric truck “ e-100 ” which is a significant improvement to our first generation vehicle . the second-generation vehicle includes a single powerful electric motor with no transmission and new lighter , high-density lithium ion batteries giving the vehicle a range of up to 100 miles . in march of 2013 , we purchased the former workhorse custom chassis assembly plant in union city , indiana from a subsidiary of navistar international ( nav : nyse ) . with this acquisition , we intend to become an original equipment manufacturer ( oem ) of class 3-6 commercial-grade , medium-duty truck chassis to be marketed under the workhorse® brand . we will need to raise significant capital in order to commence manufacturing at the union city facility . ownership and operation of this plant enables us to build new chassis with gross vehicle weight capacities of between 10,000 and 26,000 pounds and offer them in four different fuel variants—electric , gas , propane , and compressed natural gas ( cng ) . we plan to offer commonly known workhorse chassis like the w22 , w42 , w62 , as well as a new , 88 ” track , w88 truck chassis that will be offered to fleet purchasing managers at price points that are both attractive and cost competitive . at the same time , amp intends to partner with engine suppliers and body fabricators to offer fleet-specific , custom , purpose-built chassis that provide total cost of ownership solutions that are superior to the competition . in addition to having the ability to build our own chassis , we design and produce battery-electric power trains that can be installed in new workhorse chassis for class 3-6 medium-duty vehicles from diesel or gasoline power to electric power . our approach is to provide battery-electric power trains utilizing proven , automotive-grade , mass-produced parts in its architecture coupled with in-house control software that we have developed over the last five years . story_separator_special_tag the workhorse custom chassis acquisition includes other important assets including the workhorse brand and logo , intellectual property , schematics , logistical support from up-time parts ( a navistar subsidiary ) and , perhaps most importantly , a network of 400-plus sales and service outlets across north america . we believe combination of amp 's chassis assembly capability , coupled with its ability to offer an array of fuel choices , gives amp/workhorse a unique opportunity in the marketplace . our unique horsefly line of drones is designed to be the ‘ last mile ' solution in delivery logistics . we worked with the university of cincinnati to develop the horsefly to meet the rigors of package delivery and to have eight rotors and redundant systems to ensure safety in the air . today , we estimate that it costs approximately $ 1 to move a 20,000-pound diesel-powered truck one mile . while we believe our workhorse trucks can reduce the standard delivery costs from $ 1 to less than $ 0.30 cents per mile based on current costs of fuel , we expect that having drones handle the last leg of delivery could further potentially reduce the cost to about $ .03 cents for the last mile . the all weather horsefly battery-powered drone will carry up to 10 pounds of cargo with a 15-mile range . it is designed to meet the anticipated faa drone guidelines expected in 2015 , of which there is no guarantee , and is differentiated from other drones as it is designed to work in tandem with a workhorse electric truck . horsefly will deliver packages , loaded on-route by the truck 's driver , to remote locations while the driver continues on the main delivery route . horsefly will then rejoin the truck at its new location after its delivery is completed , saving the fleet operator much of the time and fuel cost of the last , most expensive , mile . also while the horsefly is atop the workhorse truck , it can quickly charge its batteries from the truck 's large battery pack . we believe this implementation is superior to the proposed deployment of other delivery drones wherein the package is loaded at a distant warehouse and the drone must make a round trip flight to the delivery address and back to the warehouse . other applications for the horsefly include transmission line inspections and agricultural surveys . 25 results of operations our condensed consolidated statement of operations data for the period presented follows : replace_table_token_5_th revenue we generated revenue of $ 177 thousand for year ended

development expenses . research and development expenses during the years ended in december 31 , 2014 and 2013 were approximately $ 3.4 million and $ 2.9 million respectively . the $ 544 thousand increase is the result of higher engineering consulting expense as well as increments in motors and batteries for e-gen prototypes . interest expenses our interest expense is incurred primarily from our long term loan with navistar in connection to the purchase of the union city plant mentioned before in the property , plant and equipment and long term loan notes to the financial statements . interest expenses during the year ended in december 31 , 2014 and 2013 were approximately $ 399 thousand and $ 258 thousand , respectively , an increase of $ 141 thousand mainly due to higher
