Which Type ? – Lotus Esprit X180R

In 1990 Lotus built 2 racing cars based on the Peter Stevens designed Esprit Turbo SE X180 which became known as the X180R and everyone appears to agree that the car was given the Lotus Type 105 number. These cars were built to be raced in the Sports Car Club of America (SCCA) Escort World Challenge by Doc Bundy and Scott Lagasse and won 4 times in 8 races.

Flush with success Lotus then built three new 300hp versions of the X180R’s the following season for the IMSA Bridgestone Super Car Championship in 1991 which Doc Bundy duly won in 1992.

There is some disagreement amongst internet sources about the type numbers of the 3 cars built in 1991 which some sources suggest were given the Type 106 number while others have it that all five race cars built in 1990 and 1991 are Type 105’s and that 20 road going versions of the X180R racer were given the Lotus Type 106 type number. Other sources suggest the 20 road going versions of the X180R are actually Type 105’s.

To confuse the identification issue further it would appear the 2 1990 race cars were updated to 1991 spec so technically these might be Type 105/106’s.

If you are a Lotus historian and can definitively put the record straight on the type 105’s and 106’s please do not hesitate to chime in below. I’d be most grateful.

The car seen above driven by Doc Bundy at Goodwood Festival of Speed carries the later 1991 spec body work differentiated by the splitter (green) that runs into extended lower front wheel arches (also green)

Chassis or Aerodynamic Aid – Lotus Ford 88

3 Replies

The Lotus 88 was a development from the ideas tested with the twin chassis Lotus 86. It differed, and was developed, in two crucial respects from the Lotus 86 it was designed to run with out skirts to seal the flow of air and would meet the 6 cm minimum ride height mandated by rules around late in 1980 for the 1981 season.

By having a secondary independently sprung chassis Lotus hoped to avoid the need to run their car with solid suspension which aided the road holding of ground effects pioneered by the Lotus Ford 79 which were sucked to the road surface as they moved through the air.

Gordon Murray designer at Brabham also came up with a solution to the 6 cm ride height rule which involved using hydraulic rams to raise the car above the minimum ride height in the pits, the only place the measurement could be checked, and lowering the ride height out once out on the track. This left the Brabham running effectively solid suspension once out of pit road.

All of the teams protested that the second Lotus chassis was in fact an independently aerodynamic aid and eventually the ruling body changed it’s mind having accepted the idea of a twin chassis car before the season started.

As a consequence after being protested during practice for the the United States West, Brazilian and British Grand Prix Lotus withdrew the 88 bodies with out ever having raced and used the more conventional Lotus 87 which used inner Lotus 88 chassis but with conventional side pods to generate ground effect and a similar hydraulic ram system for the suspension as used by Brabham.

Colin Chapman is said to have been disappointed that the twin chassis Formula One cars developed with Peter Wright, Tony Rudd and Martin Ogilvie were never allowed to compete believing that Formula One was supposed to be a proving ground for new innovation.

Engineering Adventure Get Involved – The BLOODHOUND Project

Leave a Reply

Earlier this year a team of 300 workers in the Hakskeen Pan in the Nothern Cape of South Africa set about clearing rocks and obstacles from 9,500,000 square meters of desert, by hand, in order to prepare a 19 km long surface 500 meters wide in anticipation of the arrival in the new year of what may well prove to be the biggest land based engineering adventure of the decade.

The Hakskeen Pan was chosen by former World Land Speed Record Holder Richard Noble, 633 mph in 1983, and present World Land Speed Record Holder Wing Commander Andy Green, 763mph in 1997, and their BLOODHOUND Project team as the most suitable venue to realise a £15 million pound dream in just over 80 seconds by driving their six and a half ton vehicle at a two way average speed of over 1,000 mph in 2 consecutive runs.

In order to achieve this goal some lateral thinking was required in order to get some basic backing. The BLOODHOUND project was announced in 2008 as one who’s primary mission is too inspire future generations of engineers with a program of school projects in both the UK and South Africa which are designed to inspire youngsters to see the possibilities and realise their dreams through engineering and team work. One school has already broken the Land Speed Record, for a model car.

Serving RAF pilot Wing Comander Andy Green will be taking the wheel of the BLOODHOUND SSC when it gets to Hakskeen Pan and to train for the 2.5g he will experience during acceleration and 3g he will experience during breaking he will be engaged in stunt flying exercises that expose his body to similar forces.

To propel the 6.5 ton BLOODHOUND SSC to 300 mph the team have acquired a prototype Eurojet EJ200 jet engine which produces 90 kN / 20,000 lb/f of thrust with the after burner on.

Allegedly the motor was destined for a Museum before getting reassigned to Land Speed Record breaking duties.

Two such motors are usually to be found in the Eurofighter Typhoon.

In order to accelerate another 700 mph this device will pump a ton of High Test Peroxide (HTP), highly concentrated hair dye, at 820 psi in 20 seconds through a silver catalyst which instantly decomposes the HTP into a 600°C stream of steam and oxygen which ignites the rockets fuel grain hydroxyl-terminated polybutadiene, like rubber pellets which will generate another 111 kN / 25,000 lb/f of thrust.

Already dubbed the most expensive fuel pump on a four wheeled vehicle in the world the pump is powered by a 2.4 litre / 146 cui Cosworth CA 2010 V8 motor which was designed for Formula One applications where the revolutions are restricted to 18,000 rpm.

The 18″ rocket was designed by Manchesters Daniel ‘Rocket Dan’ Jubb a self taught roketeer who has been building rackets since he was 5 years old. The first test of the BLOODHOUND SSC rocket were carried out earlier this year and the results exceeded expectations.

The vehicle shown here is a full scale mock up of the real thing which is being built a few miles down the road for me here in Bristol next to the SS Great Britain.

The 95 kg / 209 lb , Alimex aluminium wheels have been designed with the help of Lockheed Martin, at 1000 mph they will rotate at 10,000 rpm and the rims will experience 50,000 radial G !

In order to take the world record over 1,000 mph the car will have to make two runs in opposite directions with a combined average timed speed over the flying mile of over 1,000 mph. With only 19 kms of straight desert on which to play with stopping the car safely and turning it around, with in one hour, is crucial to slow the car down air brakes will be deployed once the car has slowed down to 800 mph and once the car has been slowed to 600 mph parachutes will be deployed with disc brakes available at speeds below 250 mph.

Early next year should see BLOODHOUND SSC being given it’s first test runs in the UK before being shipped to South Africa for a crack at setting a 1000mph Land Speed Record.

If you’d like to get involved with this Land Speed Record Engineering Adventure check out the BLOODHOUND SSC website linked here, the legend ‘psychoontyres’ will be appearing on the car as part of the Name on the Tail Fin program.

Wishing all GALPOT readers and contributors all the best for the New Year.

Hot Rover #3 – MG ZT-T

4 Replies

Like the MG ZR and MG ZS models the MG ZT was based on a Rover model in this case the Rover 75 and like the smaller ZR and ZS it was launched in 2001 and face lifted in 2004.

The ZT-T is the estate / station wagon version of the ZT and today’s face lifted car is said to have been completed on the 20th of January at 13:19 making it the 11th ZT to be built in 2004.

The cars chassis plate shows this car to have been intended to be biomorphic green however it was finished in shot silk chromescent, like only two other ZT-T models, one of which also has a chassis plate showing the intended colour was biomorphic green.

On 5th April 2004 the car was registered to MG Rovers Press Fleet and was subsequently used by MG Director Dr Chris Millard who had many updates and extras retro fitted to keep the car up to date with all the latest developments barring an electric sunroof.

Shot Silk Chromescent paintwork was part of MG Rovers Monogram Personalisation Programme which offered customers an exclusive opportunity for MG and Rover customers to realise their personality through automotive style.

Power for this car comes from a 129hp Turbo Diesel motor which is connected to a 5 speed automatic transmission which gives a rest to 60 mph time of 11.4 seconds and a maximum speed of 117 mph.

Just over a month after MG Rover called in the receivers in April 2005 ownership of this ZT-T transferred to the Royal Bank of Scotland before being sold on to a salesman.

My thanks to The Rover 75 and MG ZT Owners Club for the details about today’s car which is seen at the The Classic Motor Show held at the NEC, Birmingham a couple of weeks ago.

Nothing Better – Ferrari 250MM Pininfarina Berlinetta #0353 MM (0239 EU)

After beating Phil Hill on the second stage of the 1952 Carrera Panamerica Mexican hot shot Efrian Ruiz Echeverria skidded of the road while in 10th place overall on the third, of five, stage of the race in his Ferrari 212 Inter Berlinetta chassis #0239 EU.

He sent the car back to Ferrari for repairs and while it was there Efrian asked if the factory would build him a Ferrari 250MM like the one used by Giovanni Bracco which had proved to be the fastest car in the 1952 Carrera Panamerica field although transmission failure 300 miles from the finish handed a 1-2 victory to the Mercedes Benz Team.

Ferrari were happy to oblige going so far as swapping the identity from Efrian’s old 212 Inter #0239EU to that of the new 250MM chassis #0353MM at the owners request so that import duty would not have to be paid on the new car.

The 1953 Panamerica entry list included five works Lancia’s with Juan Manuel Fangio in the lead car and five non works Ferrari’s. Fangio led a 1/2/3 finish for the Lancia Team and Efrian came in as first privateer in 7th place. A result that remains the best for any Mexican driver in the original series of Carrera Panamerica races run from 1950 to 1954.

Thanks to William (WDH74) at The Nostalgia Forum I have found out what the meaning of the legend “Como 123 no hay dos” which appears to be a sponsors strap line on the bonnet of the car. “No hay dos” translates to “nothing better” from Mexican in this case nothing better than products from sponsor Industrias 1-2-3 owned by Santiago Ontanon who’s products include vegetable cooking oil and laundry detergent.

The 1953 Carrera Panamerica was #0353 MM (0239 EU)’s only in period competitive outing, the car passed through various hands and 3 restorations later the car is seen above at Goodwood Festival of Speed where it was entered by Nick Mason for his wife Annette to drive.

My thanks to WDH74, Arjan de Roos, Doug Nye, Regazzoni and Tmeranda at The Nostalgia Forum for lessons in Mexican and Mexican house hold product marketing.

Mario & Ronnie Show – Lotus Ford 79 #79/2 & #79/3

4 Replies

John Player Team Lotus hit the track running in 1978 with Mario Andretti winning the opening race of the season in Argentina and his team mate Ronnie Peterson winning the third race of the season after a thrilling last couple of laps in South Africa. Both of these victories were achieved with the previous seasons Lotus Ford 78 ‘wing car design’ for 1978 Colin Chapman and his engineers came up with something even more refined in the shape of today’s featured car the ‘ground effect’ Lotus Ford 79.

The Mario Andretti first raced a Lotus 79 in the non championship International Trophy race at Silverstone a race well remembered because the front row qualifiers Ronnie Peterson and Niki Lauda both spun of on the warm up lap leaving Andretti and James Hunt to start at the front of the grid despite qualifying 3rd and 4th. Andretti only lasted two laps before he spun out with Hunt spinning out one lap earlier at the same spot.

However for the Belgium Grand Prix there were no mistakes Mario qualified on pole and won, driving I believe from Ronnie who started 7th in the older Lotus Ford 78. At the Spanish Grand Prix Mario was I believe given the #79/3 seen above while Ronnie took over Mario’s Belgium winning #79/2 seen below. Mario qualified on pole and Ronnie 2nd and that is how the Spanish Grand Prix finished.

Mario retired from the Swedish Grand Prix after qualifying on pole leaving Ronnie to finish 3rd behind the controversial Brabham fan cars of Lauda and Watson. Bernie Ecclestone chose to withdraw the Brabham BT46 fan cars after just one race. At the following French Grand Prix Mario qualified 2nd and Ronnie 5th, however they finished 1st and 2nd respectively for the 3rd time in the 1978 season.

For the British Grand Prix it was Ronnie and pole and Mario next to him but both cars retired. In Germany Mario qualified on pole with Ronnie sat next to him on the grid and by now unsurprisingly that is how they finished the race. In Austria Ronnie was again on pole with Mario starting second however Mario retired leaving Ronnie to take an unchallenged win which would prove to be his last.

At the Dutch Grand Prix Mario qualified on pole in #79/3 with Ronnie beside him in #79/2 and the pair duly took their fifth and final 1-2 result of the season. This would prove to be Mario’s last Grand Prix win and indeed the last for any American driver and Ronnie’s last ever finish too. Ronnie crashed #79/2 during practice for the Italian GP and started the race from fifth in an older Lotus 78 while Andretti started from pole in the latest #79/4. Ronnie was involved in a start line accident which broke his legs, unfortunately during the night bone marrow from his injuries got into his blood stream and he died the following morning. The race was restarted and a subdued Mario finished sixth which was enough to claim the championship, but in truth Mario was far more concerned for Ronnie with whom he had been good friends since there time as team mates driving Ferrari sports cars in the early 1970’s. Ronnie for the second time in his career finished second in the World Drivers Championship.

The success of the Lotus 79 was largely due to what was happening to the airflow beneath the bodywork, by building the monocoque just wide enough to hold the driver with fuel tank behind him and the motor behind that, Colin Chapman and his engineers Peter Wright, Geoff Aldridge, Martin Ogilvie and Tony Rudd used the side pods to create venturi by using a low wide neck at the front entrance to the side pods and tall wide exit, with side skirts sealing airflow under the car. When the car was moving air was guided into a partial vacuum created between the venturi side pods under surface and the surface of the road and this had the effect of sucking the car to road which allowed the car to negotiate corners at higher speeds than their competitors, most of whom had still not got to grips with the wing car aerodynamics advanced by the previous years Lotus 78.

For the last two races of the 1979 season perennial Formula One under achiever Jean Pierre Jarrier joined Mario in the team Mario qualified on pole in the USA with J-PJ 8th but neither car finished in the US Grand Prix. The final race of the season was held in Canada where Mario could only qualify 9th and Jean Pierre sat on pole. During the race Jean Pierre looked set for a win until he retired with an oil leak.

Mario finished tenth. The Lotus 79’s were set to be replaced by even more radical Lotus 80’s in 1979 but everything did not go to plan and so the 79’s were pressed into service again for most of the season but were out classed by their competitors who were getting to grips with ground effects aerodynamics.

A little post script courtesy Barry Boor, Mario Andretti was invited to drive the inauguration lap of the next home of the United States Grand Prix at Circuit of the America’s on October 21st, the car he drove was naturally a Lotus Ford 79 with which he won his world Championship, you can see how he got on in this linked youtube clip.
