No Devil's advocate play here. Toyota has climbed the sales ladder step by step and they now even surpassed GM in worldwide sales. You don't get to #1 by not serving your MAIN market.
I do not dispute your statement of fact of what
is and although it may not show at times, I do appreciate your contributions. But you don't stay in the front by merely staying mainstream. They could be selling much more Landcruisers if the diesel option was offered, just listen to how many americans here are complaining about their fuel costs...
Besides, we're not asking Toyota to develop a new engine, they already exist!
So I still believe you are playing Devil's advocate, meaning you try to convince us it's OK to guzzle gas at the rate you are doing, and that people are happy their trucks are using so much gas, or at least, don't mind that they do. That, I have a hard time believing!
By using a Diesel I save on average $1,500 a year in fuel and I'm not counting the savings in maintenance and repairs these diesels usually bring as a side benefit. It may not be much for some affluent owners here on these forums who essentially bought their Landcsruiser as a toy, but not everyone has tons of money to litterally burn and there are quite a few who bough these beasts simply because the transportation conditions they live in are so harsh that it would significantly affect their bottom line if they couldn't get these (originally utilitarian) wonderfully reliable and thrifty trucks to earn their livelihood.
Tonight I went to Montreal for the Jazz festival, a 200km ride both ways (approx 124 miles). I wasn't driving particularly slowly or carefully and was even stuck in traffic for 45 minutes. That smooth engine only sipped 22 litres for the whole trip, measured at the pump a few hours ago (about 6 US gallons). Now you can't possibly tell me that the average joe actually prefers burning an extra 3 gallons for the same trip just to keep using what... This inefficient, wasteful gasoline technology? Where's the beef?
If that is in fact true, we are doomed as a society, no doubt about it!!
