Here is my attempt from 2013 to redesign the F1 calendar...
here is the original post

http://www.gmap-pedometer.com/?r=5829795I have built the extension which you designed and I extended the
straight from Ascari to a new hairpin which now makes for a possible
overtaking spot at Senna.
Malaysia
http://www.gmap-pedometer.com/?r=5829820firstly, I decided to move turn 2 furthur away to try and promote
overtaking, I then added a 5th gear chicane between turns 3 and 4 on
the current circuit. I then rounded off turns 4 and 7 on the current
track before extending the run to turn 9 and rounding the tighter 2nd
apex from turn 10,the only other change I did after that was extend
the final hairpin slightly.
Bahrain
http://www.gmap-pedometer.com/?r=5829851I started by making a flowing esse bend on the straight between turns
3 and 4 before turning my attention to the endurance layout. The
endurence layout has been made more flowing with some paribolica's,
after this the cars brake for the turn 8 hairpin which leads into the
new turn 9 which is a lot faster than it is at the moment. The next
thing I did was make turns 12,13,14 a triple apex sweeper and to end
the lap the cars bake for a more rounded off final turn.
Shanghai
http://www.gmap-pedometer.com/?r=5829884I basically went from a clean sheet for this one as there was a lot to change.
Catalunya
http://www.gmap-pedometer.com/?r=5829898Firstly, I modified the first 2 turns to promote overtaking, then the
cars arrive at the Nissan chicane which can be taken in 4th/5th gear.
Turn 10 now has a sharper entry and a more sweeping exit, then the
cars enter a new extension as they go through a sweeping s bend into a
tight hairpin before the cars go down a straight into a tight chicane
built so that the cars can go through the final 2 turns as they were
meant to be taken.
Monaco
http://www.gmap-pedometer.com/?r=5829957The aim here was to make monaco faster and more demanding for the
drivers hence the new extension near the border with France.
Silverstone
http://www.gmap-pedometer.com/?r=5830619I made silverstone feel more like was in the in the 1980's but with a
new loop which ends in a tight hairpin leading the cars onto the
wellington straight providing 2 new overtaking opportunities.
Hockenheim
http://www.gmap-pedometer.com/?r=5830617The track is as per normal until turn 7 where the cars go straight on
into the driver training center for turn 8, the cars then proceed
arround the short circuit until they rejoin the gp circuit through the
stadium.
Montreal
http://www.gmap-pedometer.com/?r=5830026I made the end of the lap more demanding by adding some fast kinks to
the back straight and just before the hairpin.
Hungaroring
http://www.gmap-pedometer.com/?r=5830084I extended turns 1/6/14 and 15 to create 3 new overtaking
opportunities on a track famous for it's percieved lack of overtaking.
Spa
http://www.gmap-pedometer.com/?r=5830695The only 2 changes I made are the hairpin extension and the bus stop
chcane now actually resemballing a bus stop.
Monza
http://www.gmap-pedometer.com/?r=5830700The only change I made here was removing the first chicane and putting
it in just after curva grande.
Singapore
http://www.gmap-pedometer.com/?r=5830701I just went from a clean sheet for this one.
Suzuka
http://www.gmap-pedometer.com/?r=5830982The first thing I did was round off degner to make it a more flowing
corner, the next mod I did was I moved 130r closer to the wall and
making it curve a bit more before its hard on the brakes for a chicane
as the cars then go round the sweeping final curve onto the pit
straight.
Austin
http://www.gmap-pedometer.com/?r=5831083First of all, I modified the esses to make them a bit more flowing
than they are at the moment, next I removed the frustrating stadium
section as it really comprimises the lap in my opinion.
Abu Dhabi
http://www.gmap-pedometer.com/?r=5831099Firstly, used the chicane after turn 4 to keep the flow going, after
that the cars go through turn 5 which is now a hairpin, the track
follows a short straight into the hairpin at turn 6 which is now
followed up with another short straight back onto the gp circuit.
Turn 10 has now become a hairpin which has a fast esse bend flowing
it, the final mod is the final 2 turns which have been rounded off to
create 1 sweeping turn.
interlagos
http://www.gmap-pedometer.com/?r=5831119The cars start the lap by going around the old curva 1 and curva 2
before blasing down the retao straight, the cars then enter a tight
chicane before the old curva 3 due to the lack of run off, the cars
the follow the the old track to feradura which has been moved forward
because after that, the cars come through the sweeper at subida do
lago before its down the reta opista. Ater that there is the longer
curva do sol before the new sweeping senna s leading directey into
sargento, the cars then come around the sweeping laranja corner onto
the current track. The final mod I made is a chicane on the
arquibancadas to slow the cars for the first 2 turns.
Now the 2 new tracks from this year... (2014)
Austria
http://www.gmap-pedometer.com?r=6465124I tried to invoke some of the spirit of the old Osterreichring but with some 2 chicanes to try and keep the speeds somewhat in check.
Sochi
http://www.gmap-pedometer.com?r=6465127I am such a big fan of the original design by Tilke but I had to do something. So I did.
enjoy and please comment and tell me if any thing can be done to make them better

Just not realistic nowadays. 
). Any results that had anything to do with the old race had no pictures whatsoever. Anyway, I was looking through my dad's collection of local history books and came across
