Hi Peter, not be
Hi Peter, not be argumentative (your points are all correct) but I think that engines blocks for diesels and some gasoline engines, even modern ones, are iron, not steel. They use cylinder liners in some cases. Iron is an excellent material and can be made in a huge variety of grades.
- - Your point is valid about the benefits of diesel, but a couple things to consider are that gasoline engines now easily outlive the rest of the vehicle in passenger cars (and light trucks). And that small turbocharged engines like the new one from Lexus/Toyota do in fact match the torque of diesels. For example the new Lexus engine in the NX has 258 lb-ft of torque from just 1,650 RPM. - - Here is a very good reason why I think that Toyota should offer a diesel Tacoma and Tundra - The buyers want it! If interested here is a link to the info on the new gas turbo from Lexus (Toyota is getting it too):
