what's the LEAST efficient car in your fleet? Is it the 8.1L Suburban, or the Pontiac with the 454
That's why I bought the Metro last year. At that time, I was rotating my daily driving between the Wrangler, the Suburban and the Grand Prix... and none
of those vehicles achieves 15 mpg in day-to-day use. The Jeep was closest at 14 mpg, but I've modified it to the point that it doesn't like freeway/high-speed driving, so it was the one I drove the least. The Suburban has not only the 496 cubic inch V8 but also the optional 4.10 axle ratio, which makes it great
for towing (it's rated to tow 12,000 pounds, which is why I bought it) but I usually see 11-12 mpg with it. The Grand Prix weighs almost 3,000 pounds less than the Suburban, but it uses a comparatively crude FiTech TBI system.(old picture)
I also drive it more aggressively than I do the Suburban... so it only sees about 12 mpg in typical driving even with its overdrive transmission. It has a very effective Detroit TrueTrac limited slip differential, and it lacks all of the modern safety equipment we now take for granted. (Traction control? Stability control? That stuff is for sissies!) As a result, I don't ever drive that car if there is even a slight
chance for rain--it is hard enough keeping the tail end straight on dry roads, and darn near impossible in the wet.
I imagine all the above will make none of you surprised to hear I have been driving the Leaf everywhere since I bought it.
