Pole Sitter & Sister – Shadow Cosworth DN5 #DN5/1A #DN5/2A

1 Reply

Things were looking up for reigning Can Am Champions Don Nichols Shadow team in 1975, the Can Am series folded, but the team kept a strong US presence with a Dodge powered DN6 Formula 5000 team which used a similar Tony Southgate designed chassis to today’s featured DN5 design.

Following the dominant trend in F1 design the DN5 was built around a slimmer lower monocoque, than the previous years DN3, but with a longer and wider wheel base and track than many.

Jean Pierre Jarier put the DN5 #DN5/1A, seen here in the first third and sixth photographs at Silverstone Classic 2013, on pole on the cars debut in Argentina, but the car never started having stripped the crown wheel and pinion in the gearbox on the warm up lap.

Jumper was on pole again at the 1975 Brazilian Grand Prix, but retired seven laps short of the finish after the fuel metering unit failed.

The non championship Race of Champions at Brands Hatch saw the DN5’s run with a new TV test card like colour scheme and Tom qualified the sister #DN5/2A, seen in the close ups at Donington Park Museum, on pole and then ran away with the race while Jean Pierre finished 4 laps down from 3rd on the grid classified 8th with a fuel pump issue.

Further highlights of the season came in Spain where JPJ finished a season high 4th from 10th on the grid and at Monaco where still driving the two original chassis Tom and JPJ qualified 2nd and 3rd respectively, but both retired with accident damage which would be the final appearance of JPJ’s #DN5 1A.

At the British Grand Prix run at Silverstone Tom won his only career championship pole but retired after an opening lap accident, by now having scored two 6th place finishes in Belgium and Holland.

In Germany Tom still driving #DN5/2A converted 16th on the grid to a fourth place finish.

Meanwhile keen to find another engine supplier the similar Shadow DN7 with a V12 Matra engine, which I looked at a couple of weeks ago, had been built up for JPJ to drive in Austria and Italy.

While the Matra proved not to be quite the fillip to the team’s fortunes that were anticipated Tom drove #DN5/2A to the teams season high 3rd place finish in Austria from 15th on the grid.

At the non championship Swiss Grand Prix run at Dijon in France JPJ was once again on pole with the Cosworth powered #DN5/4A, Jumper looked like he was going to break his F1 duck, until the 34th lap from 60 when the transmission broke and he retired from the lead.

At the Italian Grand Prix Tom once again drove through the field coming home 6th from 14th on the grid.

#DN5/2A’s final appearance came at the 1975 US Grand Prix where Tom qualified 7th but finished unclassified 7 laps down.

Having failed to convince Matra of their suitability as a partner for the 1976 season Shadow also lost their sponsor UOP meaning Tony Southgates new Shadow DN8 was put on hold while the team continued running the DN5’s in B spec, which I shall look at next year, that was introduced to meet new regulations from the Spanish Grand Prix.

Serviceability – Aston Martin Vantage V8 GTE

Leave a Reply

In 2012 Aston Martin returned to racing a GT programme with up to three Gulf sponsored works cars, split between the Pro and Am subdivisions, appearing in last seasons Le Mans Series races.

The GTE is similar to the previous GT2 incarnation of the Vantage V8 though it is lighter, features improved cooling for the driver, has improved aerodynamics and also improved serviceability which means that the motor can now be changed in an hour without altering the suspension settings where as previously the same operation took four hours.

The dry sump lubricated 4474 cc / 273 cui V8 motor produces 600 hp that is transmitted to the rear wheels by a six speed X-trac sequential semi automatic gearbox that is operated by paddle shift from the steering wheel. A carbon fiber prop shaft is fitted between the gearbox and rear axle.

To bring the car to rest ventilated disc brakes are used with six pot calipers on the front and four pot calipers at the rear.

Helping to keep the dry weight down to 1195 kgs 2634 lbs are a lithium battery, carbon fibre body panels and seat.

At Le Mans last year two GTE’s were entered the #97 Pro car driven by Adrian Fernandez, Stefan Mücke and Darren Turner finishing 19th over all 3rd in class while the #99 Am car driven by Danes Allan Simonsen, Christoffer Nygaard and Kristian Poulsen after 31 laps.

Last season Aston Martin finished 2nd in the LMGTE Pro series with one class win and six further class podiums. At the time of writing the week before Le Mans Aston Martin are leading both the Pro and Am 2013 LMGTE series.

The #99 featured today is seen at a test day at Donington Park prior to the Silverstone Six Hour race where the car driven by Jonathan Adam, Andrew Howard and Paul White failed to finish.

In Law’s Instrumental Help – Ligier Matra JS17

1 Reply

At the end of 1978 Chrysler Europe was taken over by Peugeot and almost immediately rebranded the French Simca and British Hillman models as Talbot’s resurrecting a name that had last appeared in Formula One in 1951.

In 1972 MATRA, who were taken over by Simca, withdrew from Formula One to concentrate on a successful sports car program which was itself discontinued at the end of 1974 after MATRA had won three consecutive Le Mans 24 Hour races and two World sports Car Championships under the direction of Gerard Ducarouge.

Laffite, Ligier MATRA JS 17, British Grand Prix, Silverstone

Ducarouge went to work for Ligier to design a Matra powered Formula One car in 1976, the JS5 was quite successful for a new comer and the following year Jaques Laffite won the 1977 Swedish Grand Prix driving a MATRA V12 powered Ligier JS7. MATRA stopped developing their V12 in 1978 and Ligier suffered a consequent dip in their fortunes.

For 1979 and 1980 Ligier opted for the popular Cosworth DFV V8’s and immediately returned to victory lane with two surprising wins for Laffite in Argentina and Brazil with the JS11 model, but the team lost it’s direction did not present the anticipated championship challenge. In 198O Laffite won just one race but the team scored enough points to finish second in the constructors championship.

Tambay, Ligier MATRA JS 17, British Grand Prix, Silverstone

By 1981 Peugeot returned the Talbot name to Formula One by teaming up with Ligier and an updated version of the MATRA V12 was used to power the JS17’s featured today. Laffite was to be teamed up with brother in law, ex Renault refugee, Jean Pierre Jabouille who was recovering from injuries sustained when he crashed his Renault Turbo in the 1980 Canadian Grand Prix.

Jean Pierre Jarrier stood in for Jabouille for the first two races but when Jabouille returned to the cockpit he failed to qualify for two races in five attempts so he was replaced by Patrick Tambay seen at the wheel of the #25 here for the second half of the season, but crucially Jabouille remained with the team acting as an engineer. Patrick qualified for all of the remaining races but did not finish any of them.

Laffite meantime scored a couple of 2nd place finishes in Spain and Sweden along with 3 third place finishes in Monaco, Britain and Germany. Just before the French Grand Prix Gerard Ducarouge was fired by Guy Ligier.

At the Austrian Grand Prix Jabouille was instrumental in helping Laffite choose the correct tyre to suit both the Ligier and the track which resulted in the car qualifying 4th behind two turbo charged Renaults and Villenueve’s turbocharged Ferrari.

During the race after passing Villeneuve and his quick off the grid Ferrari team mate Didier Pironi, Jaques chased down the leading Renaults. Alain Prost in the lead car retired with collapsed suspension before Jacques passed the second Renault for the lead and eventual victory when René Arnoux hesitated over taking a pair of back markers.

Jacques then retired in Holland and Italy before bouncing back with a win from 10th on the grid in Canada to put him 3rd in the championship table, 6 points off the leader, with a slim chance of winning the 1981 Drivers Championship going into the Caesers Palace Grand Prix held in Las Vegas. In the event Jacques qualified just 12th behind Championship leader Carlos Reutemann who was on pole in his Williams and 2nd in standings Nelson Piquet who was 4th in his Brabham.

Reutemann inexplicably choked under the championship pressure during the race to finish 7th out of the points while Piquet salvaged a fifth place finish, one spot ahead of Jacques, enough to win the Championship. Alan Jones won the race in his Williams thereby depriving Jacques of a third place finish in the Championship, so for the third consecutive time Jacques Laffite recorded what would be his career best 4th place finish in the final championship standings.
With only the #26 scoring any points all season Ligier finished the season 4th in the Constructors Championship.
