La Renault fa centro di nuovo. Articolo, come al solito, ben scritto.

[taglio la prova della verisone non "Cup"]
The Cup, thanks to its stiffer, lowered suspension, mechanical Limited Slip 
Diff and re-mapped ECU's feels an entirely different car to its sibling. The 
standard 250 is planted, secure and honest, while the 250 Cup adds an extra 
layer of enjoyment that is most noticeable through the steering, with 
turn-in sharpened up to the extent that it wants to go hunting corners with 
you.
How much that has to do with the more aggressive 235/35 Continental Sport 
Contact tyres on our test car's optional 19ins wheels, the 15 percent 
additional anti-roll stiffness, or the 35 percent stiffer springs I can't 
exactly say, but trust me, the Cup combination works a treat. With an LSD to 
all but eliminate wheel-slip that's already notably absent in the standard 
250 chassis, the overall package is an absolute delight when you fling it 
into corners. With a new Dynamic Management system offering three levels of 
ESP/traction intervention, you can play it safe, introduce some giggles in 
the form of increased slip angles, or throw caution to the wind and discover 
just how entertaining a well-sorted hatch can be in its unfettered state - 
the 250 Cup's back end moving around with delicious ease on the race track, 
as ably demonstrated for us by two-time French National Rally Champion 
Emanuel Guigou at the Ascari circuit, and rather less ably by me...
Yet in spite of all this raw ability, the ride maintains a fluency and 
underlying comfort that belies the ballistic efficiency of the machine 
around corners, which is why - for me - there can be no excuse at all to 
take the car without the Cup chassis. The story isn't about losing the 250's 
refinement to any meaningful extent; it's about losing its inhibitions.
That's in part due to a new version of Renaultsport's turbocharged 2.0 four 
cylinder engine, which is a pleasing thing in spite of its official 'F4Rt' 
designation. (Sorry folks, I was too busy being pleased with myself for 
noticing this unusual acronym to have noted down what it meant!) Anyway, it 
revs freely to its 250hp maximum output at 5,500rpm and even though torque 
and power drift away a little towards the 6,500rpm limiter, the engine's 
hardening roar brings sufficient reward for stretching every gear as far as 
it will go. (At 6,000rpm you get flashed by the shift light on the stand-out 
yellow rev-counter and beeped at, giving you a split-second to change gear 
and beat the limiter if you're sufficiently focused.)
Again, the Cup offers a bigger reward for enthusiast drivers here, as the 
throttle mapping feels considerably sharper - particularly in the Dynamic 
Management 'sport' and 'everything off' modes - and the exhaust sounds 
fruitier too. Major differences over its 230hp predecessor are limited to 
sodium filled exhaust valves for additional cooling, new intercoolers and a 
larger turbo but more than 25 percent of its parts are new, says 
Renaultsport, and the engine's specific output is an impressive 125hp per 
litre.
The engine is coupled to a six speed manual gearbox with a shorter shift 
than the version in the standard Megane, and taller ratios give a sportier 
feel as well as exploiting performance - 0-61mph can be achieved in just 
6.1secs and the 250 is flat out at 156mph according to the quoted figures.
With a solidity of build, and seemingly high quality materials the new 
Megane 250 Renaultsport has much to offer then. But while it's undoubtedly 
treading on German toes in many respects, there are one or two little 
foibles in its design and execution that you wouldn't expect to slip through 
a more 'ruthless' German development program. The ergonomics of the ICE and 
Nav switchgear leave something to be desired, for instance, and we found a 
glitch on both cars we drove that meant Nav system volume was inextricably 
linked to radio volume - you couldn't have one without the other, which was 
a nuisance.
Externally, too, I wondered about the 'stuck on' quality of the extended 
arches (with blacked-out fake vent behind the front wheel) and unusually 
raised sill extensions which look nice from the side, but a bit dubious when 
the door is open. (Our Renaultsport Clio's extended arches are bespoke 
panels, but that car was developed in times when there was a little more 
cash-flow around, it seems.)
But that's all a bit nit-picky really, because Renaultsport has definitely 
not skimped where it counts and the Megane 250 Cup is a terrific driver's 
car as a result, especially at the price (from �21,995). And that, unless 
I'm very much mistaken, is exactly what Renaultsport intended.

�21,995).
io lo diqui.
Peccato che per mantenere 250 cv tra bollo e assicurazione ci vuole un 
patrimonio.
