Vancouver just played host to the Epic Expo, an exposition centered around sustainable living, and one of the exhibitors there might be familiar to dedicated AutoblogGreen readers. Last year in New York, we introduced you to the alé by Fuel Vapor Technologies which, at the time, was good for 92 mpg. However, to win the X-Prize, vehicles must get at least 100 mpg and so a few changes have been made since then, starting with the names of both the vehicle and the company. Keeping the same acronym, FVT wisely removed the word "vapor" from their name and are now known as Future Vehicle Technologies and the vehicle is now known as the "eVaro." Of course, changing the name won't net you 8 mpg and so the 3-wheeler displayed in Vancouver featured a series hybrid drivetrain where once a simple gas set-up once sat.
The new configuration blows the old away in environmental performance, yet retains a similar motive performance. It is said to skedaddle from a stop to 60 mph in 5 seconds and can hit speeds of 135 mph. Environmental-wise, it can travel between 65 and 90 miles on electricity alone and attain 275 MPGe in city driving (15-40 mph) and 165 MPGe at highway speeds (45-75 mph). Lots of mileage claims are tossed about nowadays, but FVT has third-party verification of their numbers from Simon Fraser University. Hit the jump for a transcript of a letter of testimony from that institution explaining the conditions and instruments used during their tests. You'll also find a bonus video of Lacey Elliot from Driving Television learning about the eVaro from Todd Pratt of the FVT team.

I attended a test session of the FVT eVaro on February 23, 2009. A series of test runs were conducted near Agassiz, BC on BC Highway #7, immediately east of Chowat Road.
All test runs were conducted between 1430 and 1730 local time. Each test run consisted of a 1km outbound leg, a 180 degree turn, and a 1km return. Battery voltage and current was acquired and logged during each run through the use of transducers and software provided by Motec Engine Management and Data Acquisition Systems.
Meteorlogical conditions for the test period reported at Aggasiz by Environment Canada show a temperature range from 10.0 to 10.8 degrees Celsius, winds were from the North between 6 and 11km/h, light rain though not reported by Environment Canada, was evident toward the end of the test session.
The section of highway used for the test session is a busily traveled portion of public highway, it is reasonably flat and the exact grade of the highway should be a matter of public record if it is required.
The accuracy of the onboard data acquisition system was verified both prior to the test runs and then at random intervals throughout the test session by comparison reading obtained using a Fluke 190 Series Scopemeter. The margin of error between the measuring instruments was very small, and the repeatability of the results was good.
The eVaro achieved an average of 275 mpge for city driving (20-60k) and an average of 165 mpge for highway driving (70-120k).
