Car & Driver Article on V6-S
In the May issue, there is a 1-page article on AJ126 V6 and the block's common origin to the 5.0L V8. (Page 20).
I'll post a link if they put it on-line.
In net, the added block weight costs about 50 lbs. "Customer have nothing to gripe about, though...the F-Type owner would be wise to take a leave when the bar debate turns to engine design."
Hated the reference back to GM's crazy initial shared block V8/V6.

I don't see as having larger oil pan as a bad thing. Modern cars are under-engineered to have bare minimum oil pan capacity. I think larger pan will be a benefit during track conditions, so you won't have to worry about momentary drops of pressure due to Gs.

I see it as sad. the car does not warrant a purpose built v-6? I would never consider a v-6 version of the f-type after reading this.

The V6 is wonderful, reliable engine that's actually putting out more HP/liter than the 550HP V8s even in the base 340HP configuration.

Neither the V8 or the V6 are/were purpose built for the F-Type. They've both been around for years in virtually all Jaguar and Land Rover models, long predating the F-Type. However, they've both been continually developed.

regarding the v-8 hp/liter, I suspect the state of tune is quite conservative and could be making a significantly larger number of ponies if the rest of the drivetrain were up to the task?

I disagree. Good engineering is good engineering, regardless of how it's accomplished. The design has more than proven itself in the V6 configuration, and has also been used in many earlier model Jaguars and Land Rovers.
There is a long history of shared engine block family designs from virtually all manufacturers.

A compact V6 that didn't need counterbalancers, with a couple of turbochargers hung off of it would be pretty swell. Or maybe even a modernized version of the 3.5L twin-turbo V8 that Lotus used. They got 500HP out of that, but detuned to 350 to spare the transmission. Either one would have saved quite a bit of weight.
Then again, I didn't want a powered hatch or a glass roof. I'd like to see a Superlight model.
As an aside, I did drop by the dealer today. There were four F-Types in a row that looked like they were getting prepped for sale. One was a manual transmission. Then, as I was leaving, a Project 7 was pulling in. He blipped the throttle. It sounded like restrained fury.

do not disagree with much of what you say but block and engine sharing is not too common where the block of a v-8 is shared for a v-6 offering by simply not line boring the last two cylinders. maybe it was done by gm for the 3.8 but I would certainly not consider that the standard for which others should be judged.
I suppose that one could point to Porsche as having done similarly in the 4 and 6 cyl air cooled engines but they did only share a similar design and by no means did they share the block/cases.

I should not impose my will or opinion here as I am not trying to joust. my posts are just my opinion and I am new here so...I will stand down. I must say however, the f type both coupe and drop head coupe are simply the best looking sports cars on the market today. I also really like the large dual exhaust pipes exiting on the v-6 version. very aggressive!!!

The C&D estimate of extra weight was just a WAG, by their own admission. There is no question that the V8 does weigh more, as the front/rear balance of the V6 models is 50/50 and the V8 models are 52/48.

With regard to your comment in bold above, that's not what they did. The internal casting is different, and only the exterior dimension is identical. Internally, there's an empty cavity where the other two cylinders would be in the V8. The cylinder bores are obviously different, because you don't pick up 2 extra liters with just 2 more cylinders.

I think Toyota engines may have come with the Toyota chassis, but haven't investigated that. I did think about a later model Esprit Turbo for quite a while, but ruled it out as a daily driver when I drove one of the last I4models. Not that Toyota engines weren't worth considering on their own merit. That was hardly the case; they have a lot going for them.

Actually, it had quite a long run in its various incarnations. Rover got the design from Buick but it had substantial legs. Wikipedia indicates production, in its numerous variants, from 1960 to 2006. A modern version, with modern turbos and engine management, would be an interesting proposition.

Toyota chassis? I can't find any source that suggests Toyota ever had anything to do with any Lotus chassis.
I was talking about the Elise/Exige which had Toyota engines (Celica 1.8 w/ Yamaha heads) and Evora with the Camry V6. Everything I've read is that chassis design and development is where Lotus excels and is all Lotus. Lotus sold the Elise/Exige chassis to Elon Musk for the first Tesla.

OK, wasn't aware of the Lotus V8 engine's other incarnations.

I knew about the Tesla Roadster though. Tesla's just down the road. In fact, their current factory is across the street from the shop that made my last two sets of motorcycle leathers.
