From the way they respond and feed back information to the driver you'd swear the Evora is a quarter of a tonne lighter than the 911 rather than marginally heavier.
Now marginally the other way round, 1395kg vs 1430kg, advantage Evora.

I think the advantages of constructing the Evora from aluminium and fibreglass over pressed steel are probably more to do with tooling costs vs production volumes than lightness.
I'm sure that's right. As you say, it's a trade-off between tooling to build a production line or labour to build individual cars. The "problem" of that balance today is easily seen in the high retail price of cars like Ariel Atom and KTM X-Bow. Whether Alfa will ever make a bean out of the 4C remains to be seen but I reckon they'd have to sell a lot of cars to get there. Meanwhile Mazda and Porsche can churn out mass-produced steel sportscars by the bucket load with a very high level of engineering and quality control.

Yep. Low volume manufacturers can't compete by taking on mass manufacturers on their own terms - they have to play to their own strengths.

I would not be at all surprised if the 4C is never expected to pay for itself. I think it was largely a profile raising exercise, mostly aimed at the re-entry to the US market.

The Evora 400 is also something of a re-entry into the USA for Lotus - some of the extra weight can certainly be attributed to requirements of the USA - eg. Side airbags

was the case about 10 years ago and seems the always have been the trendy purist mantra,. but having owned many light and heavy cars.. I have to call boll o x on this.

it is just not the case in so many cars...

imo- there is a perfect weight for different types of cars. and that can be heavy, or light.

some of the most fun cars Ive had have been weighty,, and a couple of the very worst were the lightest.

.. this reminds me of the kind of old crap car sayings perpetuated by top gear and the like.. " you have to own an alfa at least once"

well I hired one for one week- and it was a piece of st.

yes The ability to actually stop without requiring a brake servo is another reason I like lighter cars. Sadly these days it's impossible to get type approval without ABS, which in practice means a servo, even on light things. frown
I dare say- but Sevens come without ABS which adds to the level of concentration required. That said I wouldn't dream of having a non ABS road car as daily driver(even if it were possible ) because I might be able to cadence brake but I know damn well I cannot do it anything even approaching as well as my car can do by itself.

And it's true about Alfas- I have owned not one but two. One was sublime and one appalling - and they were the same model ... (Sud Ti - and don't let anybody say they aren't proper Alfas..!)

I wonder how I've coped for the last 25yrs

I've only had a couple of cars with ABS and I disconnected it in one (a new 406) after it nearly killed me 3 times one winter by refusing to apply the brakes at low speed coming up to junctions and I rolled across them.

I can't remember the last time I locked my brakes, the only time I can remember, was 10+years ago when a dog ran out in front of my car and then just stopped - I stopped from 60 with millimetres to spare, then it wandered off.

Gotta love these "ABS doesn't work" myths.

I've got a special magnet attached to my fuel lines which gives me an extra 5 mpg..... biggrin

Yeah I made it up - WTF is wrong with you ?

Google will show it's far from a unique experience.

Ever driven a VX220 hard? Some ABS systems are truly dire. hehe

Any modern mainstream car's system can stop far, far better than me though.

One word that should describe a sports car is "nimble", IMO.

That crosses a lot of fast, good handling cars off the list, however competent they may be.

Actually I've always wondered about this saying too, I owned an Alfasud and for its time it was great, light years ahead of the rival Vauxhall Chevette or Ford Escort Mk2, but since then, most of the stuff served up by Alfa has been very, very average and backed up by awful owner satisfaction survey results. I think its time the "everyone must own an Alfa" quip is consigned to the dustbin.

With you on that. Mine I could steer on the throttle and the turn in was fantastic. I had the 10th car delivered to the uk and it was a great drive, but they did tone it down on later ones as people complained about how fast it responded !

Did flip mine end over end on the m6 though, wink

The Alfa quip is a backhanded compliment - the context was that of interesting cars which were a nightmare to own, hence you had to really love cars to put up with them. They've not been either of those things for a long time now.

Yup ABS is so crap that they banned it in F1; obviously because it was presenting unacceptable levels of danger to drivers. Same as TCS. Wish they'd ban paddle shifts in F1 though ...

I was unaware that the F1 cars used the same system as the 406 - can you give examples ?

I was further unaware that F1 took place with a powdering of snow or wet leaves on the track - when did this happen ?

Early ABS systems did come with an off switch for loose surfaces and snow. I had a moment in the Saab a few years back when it just slid slowly out of a junction on snow, abs pulsing ineffectually. I bought better tyres.

I should point out that the modern electronics have advanced to a point where - in the new Lotus range at least - you can bring a car to a dead halt in a straight line with one side of the car on tarmac and the other on sheet ice.

They used that demonstration at Prodrive with the RX-8 - two wheels on skid surface, two wheels on tarmac, hands off the steering wheel.

As an aside, the ABS isn't just about stopping shorter (though it does that if you're frozen in pre-crash rictus) but crucially about being able to steer while you're foot is planted on the (otherwise skidding) brake; ABS lets you steer with semi-rotating wheels rather than ineffectually turning the direction of the skid patch.

I loved the feel of the unservoed brakes, but if I'm tootling around with the kids then of course, ABS every time. Being aware of the lack of ABS kept me sharper on the roads and increased my safety bubble by some margin & agreed - some early ABS were shocking and difficult in extreme conditions; much better systems now I think.
