Mazda inline 6 coming out too.
What's old is new again I guess. They saw BMW and Mercedes do it. Small turbo inline 6 can be put into an engine bay just fine. I guess that's also a part of it. The turbo is easier to package than say a V6 and it's smoother? |

I-6s package fine, longitudinally. If you like your shit sideways you have bigger problems.

Quote HistoryQuoted: That's a problem with DI only engines. Port injected and dual injected engines don't generally have that problem. Quote HistoryQuoted: Quoted: Quoted: Quoted: They never should have killed off the 4.0. One of the most bombproof engines ever made. ETA: first thing I would do is delete all that EGR crap. That's an interesting take. EGR systems have been on gasoline engines for decades, and they don't cause many problems. Deleting it would likely require thousands of dollars in hardware and tuning, and even if you somehow still think it's worth it, that stuff probably won't be available as the vendors producing it have been dick slapped hard by the EPA. EGR absolutely DOES causes problems, in the form of heavy deposits on intake valves, in modern engines. If by "thousands" you mean $500 for a tuner and a couple of block off plates, then yes. That's a problem with DI only engines. Port injected and dual injected engines don't generally have that problem. Name the modern engines that are NOT DI |

The main advantage of a straight six over a V6 is that there are fewer parts. Fewer parts = cheaper to build.

I liked the 4.0 and had two jeeps with it a Cherokee and a Wrangler. But it had a major flaw, it shat right next to where it ate. Making a proper turbo instillation impossible. This new engine fixes that. Intake on one side, exhaust on the other with the proper # of turbos for making good low-end power with limited lag. Whether the rest of the engine is made to tolerate MOAR BOOHOOHOOHOOOST or not remains to be seen.

Quoted: It must be one hell of an engine if they decided to adopt an inline 6 which is typically a packaging disaster. Only one bank = more room for turbos. I'd guess the packaging is the main reason there aren't more I6 engines in cars now, but Chrysler and Mazda are both releasing new ones soon. Seems like the smoothness and performance under boost outweigh the negatives for them. I think I6s are cool and most have a torque curve (line really?) that is arousing. Only thing better is a V12. |

With modern cylinder sizing (long and narrow) and the switch to electric accessories the space needed for the engine is reduced. A lot of the newer I6s are as long as older I4s.

Quoted: Name the modern engines that are NOT DI No DI period? Off the top of my head, the Chrysler Pentastar family and Hemi family, the Ford 6.2 and 7.3 in the Super Duty line, the older Toyota stuff (1GR and 3UR), and some random Korean engines that are still holding on. But that's only part of the picture... Quoted: There are plenty that are dual injected using both direct and port injection. His point was that those engines who utilize both tend to have less issues with carbon than direct injection only engines. Exactly. Dual injection systems were a little slow to gain traction, but they've really proliferated the last 4-5 years. Toyota opened that door with Lexus products around 2006 or so, but at this point, most of the Toyota corp portfolio and a whole lot of Ford's products (including the ones they really care about) use dual injection. |

There are these things called "gear ratio" and "horsepower". They determine the speed and acceleration of a vehicle, not peak torque. An 8-speed transmission helps a lot. That engine does great in the Jeeps and pickups for that reason. |
