Even my car could easily do 37mpg, and that is with the occasional spirited drive. On my daily commute to school i have to drive up and down hills and yet, i have driven about 600km on less than a full tank of fuel (40-45L it holds).
It's always confusing because I can never remember whether Canada uses US or UK mpg (It's UK), but I've noticed car ads using l/100km more and more (like they should, we've been metric since the '70s for Christ's sake) so it's become less of a problem.
My CEO and old team leader (we'll call Bob) had a chat once. CEO: "why do so many engineers say X piece of code is bad?" Bob: "there can only be 2 possible solutions. You either exclusively hire poor engineers or they're right, and i personally believe the prior cannot possibly be the case" If you're constantly being rebuttal from multiple people for displaying a lack of knowledge or even base common sense, what's most likely? That every single person is wrong, or that you're wrong. Have a think about that.
http://theflatearthsociety.org/home/ Plenty still do my friend, and to be honest, the evidence that the earth is flat is actually pretty good if you can get something a confirmation bias. The argument is still VERY much being made. To make this all worth it, my point is occam's razor is pretty much one size fits all.
Here's something I bet most, if not all, of you have never heard of. The AMC Cowboy concept, basically a Hornet based cruck, But it really wasn't, as it had a separate cab and bed, and therefore would have technically been a mini-truck. AMC could only scrape up enough funding to make one new Hornet based car, either the Cowboy, or the Gremlin, and obviously the Gremlin is the one they chose.
I really like the '68 Dodge Sweptline. But that is more of an entry level truck, and not like this thing or an El Camino.
Makes ya wonder what AMC would have looked like if they chose that instead of the Gremlin. Would the Pacer have existed? Would AMC still be alive today (no.)? We'll never know.
To add to earlier fuel economy discussions. You can get a Caterham Seven with a 0.6l 3cyl turbo engine that makes 80hp and gets 57.6mpg combined. Closer to 45mpg when driving it hard. It also does 0-60 in 6.9 seconds, available in both kit car and prebuilt. It's also 490kg (1080lb), giving it around 160hp per ton (per UK measurements)
