this is the Lamborghini Aventador SV J
now if you know your Lambos you'll know
that J denotes the most extreme one
always have done always will do I
suspect today I learned something
interesting and that is what J stands
for J stands for Jota you probably know
but it was first worn by the mirror back
in the 1960s and the reason it's called
the J is when they wanted to turn it
from a road car into a track car the
appendix they had to fill in was
appendix J and in Italian J stands for
Jota yota yota I think in Italian
there's no vero my Italian very much
anyway let's have a look at this now
what I have here is the cheat sheet
because I've been talking through it
there's quite a lot of talk to get
through bit of complication but this is
this is what I particularly like if you
look in here look they've covered up
some of the pictures here so you can't
see what's going on with the
aerodynamics we'll come on to that in a
second let's talk about the engine first
which obviously sits in the middle of
the car back here and is still a massive
six now liter v12 naturally aspirated
power to all four wheels through the
sequential manual gearbox not a twin
clutch it's a bit it is if this car has
a weak link because I've been driving it
today it's still the gearbox it's better
than it was still not brilliantly anyway
what we have here is 717 naturally
aspirated horsepower going to all four
wheels it's not a slow car it won't
surprise you to learn in the least now
the old sv there was one thing it was it
wasn't the best to drive one of the
reasons for that was that it didn't have
enough front end on it it didn't quite
buy into corners properly a major part
of that was the fact that it only had
about 20% of its downforce on the front
axle and about 80% on the back that has
now changed because what we have down
here is a new ala system we have an
ALICE system just like the Huracan
perform ante at the front and at the
back now this one can develop a maximum
of about 190 kilos of downforce on the
front end and v-max I think they said
the
career develops about 300 kilos so it's
much better balance is about 60% on the
back and 40% on the front now that has
enabled them to stiffen up the front
suspension and so on so you the car
comes across as much more balanced I
think the front anti-roll bar 50%
stiffer and the damper rate has gone up
by 15% so anyway the little Alice slots
open and close and they bleed the air on
and off so as it comes over the front
and then you can increase and decrease
the downforce accordingly you increase
their obviously through high speed
corners and you decrease it when you're
accelerating same on the back I'd love
this look at the size of the scoop
you've got now for them for the rear our
system so in there are two motorized
ducts which channel the air out both
sides so that when you're going around
corners you can keep downforce on one
side and bleed it off on the other so
you can keep the weight balanced on the
inserts they've got a downfall still
more on the inside than the outside new
tyres Trofeo are tires which have
developed specifically for this car one
of the things they really needed for
them was stiffer sidewalls to support it
put the car I'm not surprised weren't
Vala lunar out there the track
temperature temperature at the track was
62 degrees it's 40 degrees ambient in
the atmosphere 62 degrees it's been
hitting out there and they've rebalanced
the steering torque
they've improved the steering precision
they've got rear steering that's new for
this hurricane perform ante has rear
steering it's a first for the Aventador
then we've got LD VA that's lateral and
longitudinal dynamics 40% more downforce
than an SV and yet less drag 1% 1% less
drag but if you come around the back and
just look at how many slats and scoops
there are I mean I know it's camouflaged
at the moment but there's all sorts of
aero
outlets and channels and things going on
it's quite tricked so what's it been
like on track compared with er the
standard SV so if had us driving both of
them today and the standard SV the main
difference the big difference is
confidence you get in this car and from
the moment you get out of the pit lane
the extra positivity on the steering and
then they actually
the really quite remarkable trust you
have in the front end compared with the
the SV is really impressive
this thing bites into corners in a way
that for me I don't think any
Lamborghini ever has before that is
really encouraging so it's quite a
dramatic to drive and it's just how the
system's all work together far better
than they have before it feels a much
more cohesive car deeply fast but now
the power isn't quite so alarming you
can use all 770 brake and get away with
it most of the time so it's still
camouflaged at the moment they're not
taking the wraps off it yet all they're
saying is how fast it's going around the
Nurburgring and they let us have a very
early go in it which is quite exciting
you'll get to see what this looks like
after Pebble Beach 23rd of August
that's the date you need to keep an eye
on
