What I found lacking in the article was a discussion on how non-hybrid cars performed under similar conditions. I believe that the owners reporting gas mileage well below the EPA city numbers is accurate. And I expect that the Consumer Reports study is also (under their testing conditions) is also accurate.
But what mileage would those same owner get compared to the city EPA numbers for conventional cars? And how would conventional engines fare in the same CR testing conditions?
It would be far more interesting to see the comparisons.
I agree with Lew, seems like a comparison to non-hybrids and stated gas milage is warranted.
Also, common sense needs to come into play here. If you drive your car at 65+ to work everyday, your milage will always be worse than driving at 55. I take a 30 min trip to work through mostly farmland, I can take back roads at 50 or the highway at 65. I notice the gas lasts a lot longer if I take the scenic route in my '96 Saturn. I haven't measured it, but I must get 5-10 more MPG at that generally lower speed.
Not everyone can choose how fast to drive to work or school (some places going slower than traffic can be bad for your health ), but conservation doesn't need an electric motor to be viable.
My Jetta TDI gets the as advertised 43 MPG in the city and 48-51 MPG on the highway at 80 MPH over slightly hilly interstates. The EPA shows 42/49 as the mileage estimate for the car.
I think i read somewhere that the optimum speed for most passenger cars is around 45 MPH, something about the motor's efficiency being too low at speeds below that and wind resistance being a factor at speeds above.
Are you drag-racing a Honda Rune or what? That mileage is terrible even for a lead-wrist that cruises at 80.
My Vulcan800 gets just under 50mpg I've found if I'm riding one-up in fifth gear at @65mph. I'll need to do much more "testing" at 75mph on the highway this summer before I can get an accurate number for those speeds.
I've read that hybrids need to be driven differently than conventional cars for maximum mileage. That under certain conditions, rapid starts can be beneficial for mileage, as slow speed relies heavily on electric motor torque. Then, from there, a light touch does the trick.
If you look at InsightCentral.net, there are guys all over the map with their lifetime mileages- anywhere from 40-80+mpg.
I'm also wondering if the EPA cycle that measures mileage favors electric motor assist. I -think- the battery has to end at the same level of charge as the start, but not sure.
I'm primarily interested in seeing hybrid technology make it into cars with balls. This fall, the Accord V6 is getting a 250hp, 3.0l V6 drivetrain, and supposedly will match Civic EX mileage. I'm a bit skeptical. I think real world numbers will be more like 30/30, which is still spectacular for a car with POWER. I'm after both.
Nah, around town riding with some super short highway trips. Course one was a 146 rwhp R1 and the other was an aprilia V twin, neither tuned for economy I bet I could get it down below 20mpg on the track, I never bothered with an average. I do remember riding to the gas station on the 'priller in full leathers with the bike track prepped Never into highway cruising, I took the aprilia for some long-ish trips to scrub off the 800 mile break in (varying the speed a BUNCH and lots of engine braking, all that jazz) and I probably got up into the mid 40's once, but that's keeping it under 4500 RPM and really babying the bike. I sure miss it.
Both literbikes would go 90-110 miles before the reserve light flicked on, and would take 4 gallons of fuel, give or take.
