But lesser pumping losses and less friction than a V8, so even at 340-380ps in supercharged V6 format, it offered better fuel consumption and lower emissions (and thus lower annual tax bands in most countries) than a detuned V8. In any 4 stroke engine the majority of internal friction is due to the pistons sliding against the cylinder walls. More cylinders equals more friction.

I have always been a fan of the straight 6 design, perfect primary balance, which is evident, and lovely smooth power. The final iteration of the Ford Australia straight 6 from the 1963 Falcon, was progressively developed into a modern European style engine, and given its own well deserved name, 'Barracuda' at 4 litres was a better engine than the Ford USA supplied V8 unit, with a much lighter weight and such a high power output, so much so, that it was de-tuned in the turbo variant, because it produced more power than the V8, while providing better handling for the vehicle. It became known in racing and drag circles for its ability to produce 1000 BHP. With an upgrade to titanium piston rods, it could be run much higher with absolute reliability. A demonstration of what can be achieved by throwing away the pushrod concept. It had HYVO chain driven DOHC, 4 valve heads, with high compression heads. It was not a fuel guzzler, except when pushed, so a very tractable engine package all around. So, sadly, the Barracuda engine was lost to the world when Ford Australia was closed down by head office in the US. Those who are familiar with this engine around the world still recognise its unique development cycle, and earliest frail agricultural beginnings. The versions of the engine prior to full top end work, were also an engine I enjoyed very much from as early as the late 1970s.

The best approach is BMW's. Make engines with the same bore and stroke with only difference being the length of the block, so a 1.5L 3-cylinder, 2.0L 4-cylinder, 3.0L inline-6 and for a V8 two 4-cylinder blocks could be used but BMW builds a unique engine for that.

What a good idea to save development. And it really sounds the part too.

Apparently this is or was a common thing to do in certain types of racing to get around rule books for engine displacement limits, and to save costs while doing so.

The Rover (K)V6 was part of a project in the early 90s to replace the Buick-derived Rover V8 and Honda C27A V6. It K Series-based rev happy nature meant a V8 variant couldn’t produce sufficient torque to shift a Defender / Discovery / Range Rover like the Rover V8 could. Thus, sadly, the V8 wasn’t taken further but its 90-degree V6 little brother continued. Initially hand made on a mass production scale with questionable quality control, it was launched in 1996 as a 2.5-litre engine (2,497 cc / 80.0 mm x 82.8 mm) in the 825i, giving 130 kW (177 PS) @ 6,000 rpm and 240 Nm @ 4,000 rpm with the redline at 6,750 rpm. Rover engineers said it could go up to 2.7 litres (2,693 cc) - giving the stillborn V8 a maximum capacity of 3.6 litres (3,591 cc). In 1998 the V6 was heavily revised for the 75, becoming nearly a new engine in the process. The core block was carried over but everything else was changed. It also gained a smaller 2.0-litre (1,997 cc) with a shorter 66.2 mm stroke. This produced 110 kW (150 PS) @ 6,500 rpm & 185 Nm @ 4,000 rpm. Continuous redline at 6,750 rpm and an intermittent 7,250 rpm limiter. Maximum speed: 210 km/h (130 mph). The revised 2.5-litre (2,497 cc) gave 130 kW (177 PS) @ 6,500 rpm and 240 Nm @ 4,000 rpm. Maximum speed: 220 km/h (137 mph) - although owners have got them to 240 km/h (149 mph). For 2001 the 2.5-litre variant was given a small hike in power and torque to 140 kW (190 PS) @ 6,500 rpm and 245 Nm @ 4,000 rpm for the MG ZT 190 / ZT-T 190. Maximum speed: 225 km/h (140 mph). In 2004 MG Rover Australia went to Sprintex to help with a supercharged version: ZT 220S. This produced 165 kW (225 PS) @ 6,400 rpm and 290 Nm @ 4,100 rpm. Maximum speed: 234 km/h (145 mph). However, if Rover 75 2.5 [177] models (above) are anything to go by, it’ll probably go on to 250 km/h (155 mph). The 2.0-litre variant also appeared in 45 2.0 automatic models for BTCC homologation. MG Rover entered the ZS in the British Touring Car Championship in 2002 powered by a 2.0-litre V6 with 200 kW (272 PS). From 2004-2006 private teams ran ZS models with some success. *sorry…*

@@floydblandston108 It would have been better to have read my original comment in full before replying! Nowhere in my comment did I say the Buick-derived V8 and (K)V6 shared any design or parts commonality. To repeat my original comment, the (K)V8 and (K)V6 were a project to replace both the Buick-derived V8 and Honda C27A V6. The stillborn (K)V8 and production (K)V6 engines shared engineering concepts with the K4: sandwich design with long bolts holding the engine together under tension, block / cylinder liner design etc. As I said in my original comment, the (K)V6 was heavily revised, pretty much becoming an entirely new engine, for the 75. Julian Donald, engineer at Longbridge, explains one of the changes: "The cylinder head design of the early KV6 used in the 800 were basically just three-quarters of a four-cylinder K Series, but for the 75 the whole engine was redesigned to make it narrower to fit under the shorter bonnet." Another engineer, Brian Gunn, goes further: "The differences between the early and late KV6 are that the block/liners are dimensionally more accurate, with more tolerance bands. The heads are the same, although Rover changed the top covers." "The inlet manifold is totally different - it does not have the dual butterfly-type throttle body like the early one. The engine management has also been changed in favour of the Siemens 2000 system over the earlier MEMS 2J system.

It's down to emissions and therefore annual tax costs for owners in most countries. 8 cylinders is almost always worse on emissions than 6 cylinders so the V8 will almost always sit in a higher tax band. In most markets Jaguar operates in, and particularly the home market, V8s are deeply unpopular except in their halo-model form. Almost nobody wants less power, they want lower ownership cost. Even this V6 was dropped from the XE early on when a turbocharged 4-pot offering almost as much power for less cost was introduced. In the old X-Type the Duratec based 2.1 petrol V6 didn't survive long after the 4 pot diesel arrived offering almost identical acceleration but with much better fuel consumption - the 2.1 V6 was particularly stupid because it cost the same to build as the 2.5 and 3.0 engine, but Jaguar had to sell the 2.1 at 2/3rds the price of the 3.0 version!

Ford did something similiar with their cologne OHC V6. The heads were the same. So in effect both heads could be cast from one cast instead of a left and right mold. Just some changes in the water jacket and plugs iirc but both heads could be used interchangable with the exceptions of a few sensor plugs. But this did result in that rear side timing chain and jackshaft.

(bought for 600, put 200k on it and sold for 600, still running today) I have several cars with this motor and have rebuilt a few of them and if you take care of them even after hundreds of thousands of miles the internals look like the internals of most motors with like 60k. Plus, many of them came factory supercharged, which is super cool. My gtp with a supercharged 3800 always puts a gigantic grin on my face. 500 dollars in mods and it's making about 320 whp. Plus, cruising on the highway they all get about 30mpg. Don't get me wrong, the cars this motor came in are usually nothing special, but the gm 3800 is an absolute gem of a powerplant. Not easy to make crazy horsepower with them but they are very cheap to own, you can have plenty of fun with them, they are easy to work on and they last absolutely forever. A 3800 will run like shit for longer than most motors will run period. It's one of the only platforms to come out of the U.S. that competes with the stuff toyota and honda were putting out at that time. Had comparable and even better gas mileage in some cases, made more power, and keeps up in terms of reliability for sure.

VisioRacer actually made a video on the PRV engine kzread.info/dash/bejne/ia2am5SBhJPdqM4.html. My experience (as working in aftersales) on PRV is more that the earlier versions are difficult to tune (K Jetronic with breaking fuel lines, or multiple carbs hard to synchronize , dual ignition to time, CO2/CO to be adjusted on each bank of cylinder...) and oil leak prone. Once the engine received split crank, silicone based gaskets and Fenix fuel injection, the N.A. versions become bullet proof engines. Turbo versions if not abused will also be super reliable. Yet fuel consumption will never be great.

Learnt a new word. Lackadaisical 👍🏼

I was confused about what the problem was, until I saw the block casting for the 'V6'. Holy shit that is bad. No other manufacturer has even considered producing something like that, even if it saved money. I'm surprised I've never heard of this.

My question is: if removing 2 cylinders this way is good enough for most applications, why dont they sell the v8 with a low power mode to save fuel most of the time? Wouldn't a 250hp tune on this v8s be feasible instead of cutting 2 cylinders for better mpg?

It's because the problem with a V8 isn't adding fuel or not adding fuel to the cylinders, it's the friction losses of the pistons moving in the cylinders. It's the friction you're stuck with whenever the engine is running, no matter how much power you do or don't need at the time, which contributes most to the fuel consumption and emissions, the latter translating to tax bandings for most countries. Nobody wants low power mode, they want low running cost mode, and the best way to reduce ongoing costs (tax, fuel consumption) is to lose cylinders.

I had one of these supercharged 3.0 V6s in my XFS. It was fucking amazing. No idea it was a V8 in a previous life though!!

This is a really good, informational video. No matter how true it is, it brings a bit of a negative connotation that this V6 should be considered undesirable. That's just my take on the presentation. No slight intended. I own a Jaguar XE with this engine and it is an absolute THRILL to drive. The power is almost scary (full disclosure: Mods to computer map and supercharger overdrive put it just over 450 HP). The exhaust note is just fabulous too. If you ever get to drive or own a Jag with this engine, I guarantee you'll be in a M5 KILLER and have adrenalin overkill. Thanks for the nice video! --Fink

Wow, I already hated 90 degree V6 engines for various reasons, but this takes it to a new level. If a company wants a V6 engine, don't make the inherently unbalanced 90 degree type. Either make a 60 degree V6 or make a VR6. I hate balance shafts with a passion. To me it's like making an engine carry an extra weight continuously because the engine was a stupid idea to begin with. Some people like to talk about the size constraints of an inline 6 and V6 and how it affects car design. When they ask, I tell them to look at a Nissan 300ZX Twin Turbo and a Toyota Supra MKIV side by side. That makes it much easier to see the space an inline 6 takes up, and how a car must be be built to accommodate it.

@nerd1000ify

Жыл бұрын

To have a natural even firing order a V6 needs 120 degree bank angle. That's barely narrower than a flat 6, hence 60 and 90 degree sixes, which both need offset crankpins. V6s always need a balance shaft to cancel out the rocking couple that comes as a result of having an odd number of cylinders per bank. If you want balance shaft free operation you need an inline or boxer 6. But they have their own downsides, e.g. inline sixes need heavy harmonic dampers on their crankshafts because their length reduces the torsional rigidity of the crank.

@Skyline Fever well not huge necessarily, but carefully optimised so that the engine mounts won't amplify (resonant frequencies etc. are important) or transfer the vibration into the car. I think this is increasingly common these days, especially since many small cars are going to I3 engines that have the same balance issue but would experience even more of a penalty from the balance shaft due to their lower output. My original post I miss spoke a bit, the text implies a V6 must always have a balance shaft when I should have said it needs one if the rocking couple is too large to be dealt with by other means in our specific application. Obviously in a luxury car we would be more worried about some vibration than in a truck.

That would explain why the v8 and v6 engine covers looked the same under the hood.

Ya but it was a dog of an engine

It's not like you say with duratec story. The first v6s after 93 to 96-97 had 2564cc and 170hp. All 2.5l Duratec are equipped with the IMRC system - variable length and capacity of the intake manifolds, which increase the torque at low revs and boost the engine at high revs (operating similarly to the ram air system - the engine is charged with the momentum of the air-fuel charge reflecting inside the intake manifold) In facelift models after 97 mondeo mk2 2.5 l capacity was 2544 cm3, the power remained unchanged. A sports version of the st24 / svt with a power of 190 horses was created with an increased cross-section of the intake manifolds (these intake manifolds - black, not silver, are very sought after and are an easy way to increase the power in a regular v6). In 1997 (in cooperation with Mazda and the Ford Performance USA branch), the ST200 SGA version was created with a capacity of 2498 cm3 and an even larger throttle, increased compression ratio and a pwm controlled fuel pump that generated 208 horsepower. Engine parts are interchangeable with each other on all ford2.5L models except for the crank and piston system. The ST 200 also has more aggressive camshafts, but they fit a regular v6. On the other hand, the 3.0l MEBA version with mondeo mk3 and mazda is a completely new engine, with a different intake manifold, which from spare parts for 2.5l has only part of the engine accessories, e.g. feet, alternator, water pump, coil, timing gear. Engine 3.0 was designed by Mazda engineers - for Mazda 6, Tribute, MPV based on the ST200 engine and generates 226 horsepower. There was also a Duratec SE 204hp version - REBA - different camshafts and a smaller throttle. At the time of the Ford/Jaguar merger, Jaguar received the early 3.0L engine blocks, but decided to return the cylinder heads for rework in porsche. Depending on the application, jaguar 3.0v6 has from 234 to 244 horses (x type s type). There are no matching parts from the Jaguar to the Ford, they are very similar to each other and can even be mounted together, but they will not work properly, e.g. crankshaft bearings. In '98, Jaguar customers started complaining that their 3.0Ls were gas-guzzling, so Jaguar designed a 2.5L capacity of 197hp. However, this was not enough and Jaguar wanted a more economical petrol version in the x type model, so it created a 2.1l version with 156 horsepower. This version did not have the possibility of configuration with 4-wheel drive (only front-wheel drive, but the 2.1 engine fits the gearbox from the 4x4 version). Jaguar engines have also been put into late Ford Mavericks, it is a Mazda Tribute in fact, on Mazda engine accessories.

I like Jaguar and I own an XK X100 but Jaguar hasn't been the same for a very long time. They keep chasing BMW and missing the point of what made Jaguar desirable. Their sales figures for the F-Type and XK X150 reflect that with well under half the sales the XK X100 had. The V6 was a shit idea, whoever came up with that should have been sacked. No need to have so many engine options, the V8 was already very fuel efficient being able to get out 30+ mpg UK on the motorway and low to mid 20 mpg on normal roads. Only ever need the naturally aspirated V8 and the supercharged V8 in different capacities. They should have kept the 4.2 around for the more luxury cars and the supercharged engines in 5.0 versions for the more sporty or higher end performance packages. Should have offered a manual for the V8 instead of a V6. Lexus LC500 is what Jaguar should have made. They are just taking Jaguar sales instead.

One word. Cost effective. It's that simple. Tooling is almost similar. Manufacturing is almost similar. This means it can be offered at a "good" price.

Fuel economy was worse than AJ133 but in 2012 they were bankrupted and being sold to Tata they could not used the Duratec anymore. V6s can be as refined as I6s, just have a look at Busso's engine, or the V6 made by Alfieri in Maserati also with little money and derived by a V8.
