Sad part is its still a st chassis design, just a very expensive one.
What, you don't like all the pre-arranged fail points in the pretty curved tubing?

I would guess this is titanium alloy rather than pure titanium?
Correct, I doubt it would be CP Ti (commercially pure). It would 3-2.5 (3% aluminium and 2.5% vanadium) or if they feel flush 6-4 (6% aluminium and 4% vanadium).

I chose Ti for my mountain-bike frame as it flexes longitudinally and therefore adds comfort without any weight penalty compared to CF and a little gain compared to steel. But the main benefit is that it doesn't rust unlike steel and is indestructible, unlike CF.

Flex is the presumably the last thing you want on a car chassis, so they must have reinforced it quite a lot hence the modest weight gain.

Never mind the titanium, why is that bloke wearing his wife's jeans?
rofl

Also looks like he needs to lose more the 7% in weight hehe

that does not help, but it's issues are somewhat more fundamental than that.

Like what? Have you driven or owned one?

the whole design from a chassis perspective is just wrong, (and no I am not about to detail it all as that would take a book).

Put simply, the basics are just wrong, kinematics are laughable, hence why they just don't handle/work outside of top gear bragging rights.

no, I have never owned one, yes I have driven a few and yes I have worked on a few.

Is that because of the nature of the chassis that restricts the positioning of the linkages and dampers ?

I own a few and seen them work VERY well on the track and off the track. I'll admit that I don't know much about chassis design or preparation, but I've seen some famous race drivers come off the track and say what a great car it was and put some impressive track times in. Not sure why you're a hater on them, they do what they say on the tin...just great fun.

Would be interesting to see a back-to-back test between this atom and the normal one on something like top gear to see just how much difference it actually makes.

never seen one post anything like a decent laptime... (you only have to look at TSL)

compared to a Caterham/Lotus/etc they are nowhere, even with a massive power advantage.
