  • Engine upgrade

    Hi Guys

    Just wondering if anyone out there has heard if Toyota is due to upgrade their standard engine soon?

    Cheers.

      Wooley, you crack me up :-)
      Geoff

      Im not Bogged - I've just lost traction. . . . . and now I'm showing the wife why I bought those Maxtrax, and the tyre deflator, and the compressor, and the bullbar, and the winch, and a lot of other goodies I've hidden in the Prado

        Happy to contribute but I currently have a Hilux. In the process of signing up for a prado and this was one answer I couldn't find. The dealer has told me there are no changes from MY12 - MY13.

        Oh, and by the way - thanks for the warm welcome woolley, very helpful. Can you remember back 2006 posts ago when you did your first one...

          I can actually... It was in the introductions thread...

          But seriously, welcome.

          As for new motor... why would you want one... the 4cyl is fine, and a new motor is likely to have teething problems.

          Also they usually test new motors elsewhere in the world first and everywhere else still seems to be using the 1kd?

            I'm wondering this as well. Toyota has signed a deal with BMW to use there diesels in future vehicles.

            The Altitude has just been released in April likely to get rid of old stock before the makeover/changes coming.

              I agree that the 4cyl is fine and seems to do the job, however I have heard that a higher kW engine is used in Europe. I'm no expert but it appears that Toyota has one of the lower spec'ed engine kW's on the market here in Aus...I also agree about the teething issues if it was a new motor...

                The D4D used in Europe is exactly the same engine, but with a shitty DPF. DPF cause more issues than they solve for some manufacturers (I'm looking at the CX-5, Mazda!)

                  the partnership with Toyota and BMW was only mentioned in regards to small capacity diesels for Europe.

                  It would be nice for the Prado to be fitted with a twin turbo V6 with a 6 speed auto, but who knows. Personally I am happy enough with the go of the 3ltr diesel for normal driving. But would like them to raise the towing capacity and then bit more grunt would be nice.
                  The Landcruiser is just too big a car now, that and the price rules it out for me.
                  stepped up the a 200 LC for towing,
                  but had a 2012 and 2010 150 Prado GXL auto diesel in Graphite with Bridgestone D697 A/T. Dobinson C59-300/325 and Bilsteins. Accessories : two baby seats. Sidewinder`s Dual Battery isolator and rear power outlet kit. Pirana Battery tray, Hayman Reese towbar with Toyota wiring kit and Brains`s guard.

                    A V6 diesel is my dream Prado complete with 3t towing capacity but that isn't about to happen as it will take too many sales away from the 200.The 200 is dearer but you sure can drive them for a bargain. Also have a look at the spec sheet for a size comparison it may surprise you. The 200 is only 15mm higher 20mm longer (prado has wheel on back door) but is 85mm wider and this makes it look so much bigger than the Prado,but they sure have got a lot of room inside

                      A diesel typically produces better torque via fewer larger pistons rather than more smaller pistons. So if Toyota were to put a V6 into the Prado with the same swept capacity of 3.0 litres, the pistons will get smaller, and this will make the engine more of a revver.

                      Look at the Nissan Pathfinder or Navara V6 turbo diesel which makes 550 Nm. Most of the useful output of this engine is at the higher rev range, and when pushed into the higher revs to extract that torque, fuel consumption suffers.

                      So the engineers will have to work out a way of getting more air into the engine at low revs to get the torque to come on early in the rev range - one way is via variable vane turbo technology. When the revs are low, the vanes close in on the turbo, making it spool up quicker, and when the revs increase and exhaust pressure increases, the vanes open up, making the turbo "larter".

                      A variable vane turbo will help but it'll never be as effective as sequential twin turbo setup, where there is a dedicated small turbo mated to a larger turbo. Small turbo spools up very quickly, but runs out of puff so that's when the larger turbo kicks in.

                      BMW have adopted this strategy with their twin (sequential) turbo in the X5 3.0 SD. Now it's getting quite a bit more costly and complicated because it's a twin turbo setup. Even Land Rover have adopted this approach - their 3.0 TDV6 is also a sequential twin turbo setup, to address the low rev torque delivery characteristics and yet maintain driveability all the way across the rev range.

                      Finally, there's a need to plumb the intake manifold to both Vee banks, so the plumbing gets long and convoluted, taking up valuable space in the engine bay that could make servicing the engine much more difficult and creating lots of heat discharge. In the case of a LandRover D4, the entire body is sometimes removed so that certain parts of the engine can be accessed for repair due to the lack of space to work on the engine. Not something that can be done in the back of Bourke and beyond.

                      A narrow V6 engine will also require counter rotating balance shafts to smooth out the inherent vibrations.

                      Now this engine becomes a lot more expensive to build - and Toyotas are already expensive enough as it is - notice how the Pathfinder and Navara TDV6 engine is significantly dearer than the 4 cylinder 2.5 TD motor.

                      A TDV6 Prado would be a fairly expensive vehicle, and the market may not want to bear that cost, and the complexity will make it a more
                      expensive proposition to maintain.

                      In certain countries, the swept capacity has a direct correlation with road tax. So the bigger the engine, the more expensive it will be to keep registered on the road. So Toyota need to be careful not to alienate their customer base, even though this isn't an issue in Australia.

                      Maybe Toyota should look at ways of increasing the output from the existing engine without increasing complexity of engine size. VW did this on the Amarok by fitting sequential turbos on their latest incarnation of their turbo diesel. More power but not a peaky engine to drive.

                        how about a 4L 4cyl... everyone loves a litre (or more) a cylinder

                          its the 85 mm wider that makes it a bit too big for normal running around duties. I could come at the 100Series, but the 200 is getting too wide.

                          from what I understand with 4cylinder motors, around the 3 to 3.2 is about the practical limit in so far that you need balance shafts etc. So I don`t think we will see a 4ltr 4cylinder.

                          and yes agree that a small capacity high torque diesel V6 would be expensive and technical and then would need to be reliable too.

                          What I can see happen is that they might leave the current D4D and tune it for more efficiency and fit a hybrid electrical system like they do on the Camry and Lexus etc. The systems are getting lighter and more capable all the time.
                          stepped up the a 200 LC for towing,
                          but had a 2012 and 2010 150 Prado GXL auto diesel in Graphite with Bridgestone D697 A/T. Dobinson C59-300/325 and Bilsteins. Accessories : two baby seats.

                            Or put the old 6cyl from the previous model cruiser in the Prado.......now that will make Roo happy!

                            FYI chaps I started a thread on this a while ago as rumours were out back then that the next engine was a V6 designed by Hino.

                              Having a litre (or more) a cylinder is fine, look at trucks.

                              The cummins b motors have a litre a cylinder on small displacements: 4 and 6 litres and they're fantastic.

                              That said, a litre a cylinder would end up with characteristics the majority of 4wd owners wouldn't like.
