I took a 2006 Kia (owned by Hyundai for several years) Grand Carnival people mover for a test drive yesterday and the salesman (at a Kia Dealer) said the 3.8L V6 engine is actually made by Mitsubishi. I have noticed in the past that Mitsi tech is used by a few manufacturers, e.g. Mitsi 3.5L v6 parts are the same as used on some hyundai engines. Mitsi onsells a lot of tech, even the cheap chinese utes GW are using old Triton tech.
It is specced at 185 Kw which is about 10kw up on the 380 and uses a 5 spd tiptronic gearbox, not sure who makes the box though. For a large peoplemover I was very impressed with the acceleration and the way it drove - the space was pretty impressive.
Anyway, does anyone know what gives it the extra 10kw? It seemed to rev more freely so I suppose the exhaust might be one possible area...

its the Hyundai Lambda 3.8
The Lambda RS 3800 (Rear-drive Sport) longitudinal Lambda engine variant can be found in the 2010 Hyundai Genesis Coupe. In this application power is rated at: 306 hp (228 kW) @ 6300 rpm, and 266 lb·ft (361 N·m) of torque at 4700 rpm. Another longitudinal version with standard output can be found in the Kia Borrego, but all other vehicles using this engine have a transverse mounting configuration for front-wheel-drive. The engine is an all aluminum mill, featuring DOHC and 24 valves.
So DOHC adds the extra 10kws??
Its not a mitsubishi engine at all, it is fully designed and built by hyundai and has no relation to the 6G75 380 engine.
The lambda comes in all manner of displacements, 3.0, 3.3, 3.5 and the big 3.8. Awesome engine

I'd like to inspect the block itself, I know Hyundai have been using mitsu short blocks for yonks...

Not in this one, its an entirely new design. The previous sigma v6 was based on the 6g74.

I should have also mentioned that the dealer was a Mitsubishi/Kia dealer so I don't know why the salesman would say otherwise ... they always tell the truth don't they ;-) ... I still suspect Mitsi involvement though, knowing the hisotorical use of Mitsi tech by Hyundai...

You might suspect it but you'd be wrong. In fact one gets the impression that the Mitsubishi Motor Corporation has been a ship without a rudder for some time and that it is Hyundai that are forging ahead with bold new designs (Genesis, Veloster and the whole I -series) in fact the R&D departments of HMC are significantly larger than that of the old master MMC and it may well be that we have reached the point that the Master has been overtaken by the student.

Exactly right
While the block is all new, there is speculation that the bolt pattern (bellhousing) is the same as a 6G7X. nobody has been able to confirm it though. The Delta was the same as the 6G7X for bolt pattern.

Just a little update...
I had to replace the TJ after it got rammed into the cars in front while stopped for a red light, it didn't look too bad but was enough for the insurance company to write it off. Anyway, got a Kia Grand Carnival with the 3.8 engine and have had it for a month. This motor is pretty dam responsive, would have been good to have something like this in the 380. It's a little scary in a van as the pick up is pretty dam agressive and it will wheel spin fairly easy. Fuel economy isn't that great around town but considering it weighs in 400kg heavier than a 380 and has a similar power output etc it is fairly proportional. Around 16-17 l/100kms around town (the 380 is around 13-14 l/100kms) and 11L/100kms on a trip. All the reports I have seen since seem to agree with the comments above, that it is a hyundai engine. It looks like it is a pretty capable motor with upto 230-240 kw in some versions, although it would be insane to do anything to the motor in the carnival as it struggles for traction, as it is. But in a sedan...

sounds a bit high to me.

I consistently get 11-12L/100kms around town. 9-10 on a trip sometimes even less

Never less than 14 around town for me but certainly under 10 on a trip. GT's are heavier maybe thats the reason

The 11L/100km was for the Kia - not bad for a 2000kg vehicle, the 380 is around 9-10 L/100kms. My around town at 13-14L/100kms for the 380 might be a little higher than most because Canberra has a lot of 80km/hr roads.

I reckon 13-14 L/100km on an 80kmh road you must be holding it in 2nd gear....

80km/hr is the sweet spot for the 380 for econ
Its the sweet spot for almost any modern car

If you have visited Canberra before you will know what I mean, most of the main roads connecting the suburbs are 80km/hr and there are lots of traffic lights and round abouts on those roads so you are always getting upto speed and slowing down again.
I believe there are actually quite a lot of similarities between the 6G7x family and the Lambda family. It appears that many of the design features are present in both, particularly the bottom end. There was a thread on here a few weeks back about using Hyundai V6 performance mods (cams etc) in 6G7x engines. I stumbled across some really good info on one of the US Mitsubishi Eclipse forums. Side-by-side, the engines are very comparable indeed. The major differences seemed to be in the heads, with the Lambda sporting new tech that allows the NA motor to produce very good power.

AAhh but good old Adelaide and roadworks. We have 110,100,90,80,60.50.40.25.
They have just changed some fast long stretches in the Barossa from 110 to 100 and 80 due to accidents.
