Sold for $381,000 at 2006 Bonhams. This vehicle is a 1974 AVS Shadow/Chevrolet DN4 CanAm Sports-Racing Spider with chassis number DN4-2A. It is the chassis driven by British racing star Jackie Oliver in which he won the 1974 CanAm championship title. Oliver's racing career began with front-drive mini saloon cars, progressed to a wooden-chassised Marcos GT and then a Jaguar E-Type. Through time, he went to single-seaters, then Formula 3 and International Formula 2. In 1968 he was World Champion Driver Graham Hill's team-mate in the Formula 1 Lotus program. He raced in Formula 1 for a number of teams, including BRM, McLaren and Shadow cars. In 1969, he won LeMans while driving a Gulf-JW Ford.
In 1969 he raced in the CanAm series in Peter Bryant's Autocoast Ti22. From 1972 through 1974 he drove for Don Nichols in his AVS Shadow CanAm cars. He also drove their F1 single-seater cars at the time as well.
The fuel shortage of the early 1970s had CanAM change their regulations considerably, limiting fuel to just 37 gallons per race. The gas tanks shrank in size, many had been over 80 gallons. As a result, the cars decreased in size as well. The DN4, in comparison to the DN2, was considerably smaller, now just 100-inches in length. The AVS team claimed their V8 Chevrolet engine produced 735 horsepower. It is believed that the real figure was closer to 800.
Jackie Oliver kicked the season opener at Mosport Park, Canada to a wonderful start. He drove his DN4 to pole position with a qualifying time of 1 minute, 14.5 seconds. He and his teammate George Follmer finished first and second. Behind them were a McLaren M20 of Scooter Patrick, Bob Nagel's Lola T260, the Motschenbacher's Mclaren M8F and Gene Fisher's Lola T222.
At Atlanta, Follmer qualified ahead of Oliver for pole position. The race, however, was won by Oliver with Follmer finishing in second. At Watkins Glen, the same scenario played out again. Follmer qualified for pole position but finished in second. Oliver won the race while starting second. Olive won for the fourth time at Mid-Ohio. Follmer qualified ahead of Oliver at Elkhart Lake, and both he and Oliver ran uncontested through most of the race. Both cars suffered mechanical difficulties and retired prematurely. The race was won by Scooter Patrick in his 1972 McLaren M20.
At the close of the season, Jackie Oliver had 82 points and emerged as the 1974 CanAm Champion Driver. This car, driven by Oliver, was offered for sale at the 2006 Bonhams & Butterfields auction held at the Quail Lodge in Carmel, California where it was estimated to sell between $240,000 - $280,000. Considering the history of the car and its dominate season, it was not a surprise to see bidding exceed that estimated value. The high bid landed well above the estimate, winning at $381,000.

This is the car that won the Can-Am series in 1974-which was the last year of the Can-Am. The DN4 was a new design for 1974 and proved to be an extremely quick car, that was relatively easy to drive. It dominated the series winning 4 of the 5 races [Read More...]
In 1971 Don Nichols founded Advanced Vehicle Systems and began producing the cars known as Shadows. Mr. Nichols was very familiar with innovation in the automobile industry. This would lead Nichols to become quite influential in the Far East, which e [Read More...]
The Advanced Vehicle System (AVS) began in 1970 and created by Don Nichols. The cars were called Shadows. The company was established with the purpose of creating racers that had limited aerodynamic drag through minimal front area on the cars. Nichols approached Firestone with a request to have tires created that were smaller in diameter to conventional race tires at the time. The reasoning for the request was to help in the reduction of aerodynamic drag. When other manufacturers were using 24-inch tires in the front and 26-inch in the rear, Nichols wanted to use 17 in the front and 19 in the rear. There were flaws to this thinking; the smaller tires meant smaller brakes and rotors which meant less stopping power. Another side effect of smaller brakes was that they were unable to dissipate the heat fast enough and this lead to various other tires.
A Chevrolet big-block enginge was chosen as the power unit for the car. Due to the design of the car there was no room for the radiator to fit into the body. Trevor Harris had designed the car. The only logical place to fit the radiator was to mount it on the rear wing. This did not work well. Though many of the ideas were innovative in concept, they were failures in reality. The car, driven by George Follmer and Vic Elford, failed to finish many of the races that it was entered.
In 1971, personnel from a company named Autocoast merged with AVS. Autocoast had debuted their Ti22 racer in 1969 at Laguna Seca. It too was propelled by a Chevrolet V8 powerplant. It had been designed for CanAm competition by designer Peter Bryant, who created a very aerodynamic design. The chassis was a monocoque structure comprised of aluminum and titanium. This marked the first time that titanium was used extensively in a car. The name of the car was rather fitting, as 'Ti22' is the atomic symbol and weight of titanium.
At its inaugural debut, the Ti22 was driven by Jackie Oliver and finished in 13th place. The next race was at Riverside where the vehicle qualified fourth but retired prematurely during the race. The car's sponsor was Titanium Metal Corporation so when the titanium suspension piece broke, the team officially documented the problem to be related to the transmission in order to elevate any potential sponsorship conflicts.
For 1970 Jackie Oliver again drove the Ti22. The second race of the season ended in a tragedy for the team as the car flipped off the track on the first lap. Oliver was ok but the chassis was destroyed. The team was unable to get another car ready for most of the season. By the time a replacement car was ready, there were only two races left. Oliver drove the car to a second place finish in both of those races.
When the personnel of AVS and Autocoast joined forces, they agreed upon creating a racer that utilized the strengths of both of the cars. Jackie Oliver was chosen as the driver. Universal Oil Products became the teams official sponsor.
The car, dubbed the MKII, was given larger tires than the one used on the original AVS car. In the front, the tires measured 18.8 inches while in the back they measured 22.3 inches. Though larger than the AVS car, they were still smaller than the tires used by other CanAm cars. Titanium was used in the car, though not in any major quantities.
The car was ready for the 1971 seasons. Oliver qualified the car very well for many of the races but he was unable to finish nearly all of the races. The car finished only race and that was at Edmonton where it achieved an impressive third place finish. For the following season the team made the change to conventionally sized tires. In order to accommodate the larger tires, the body was enlarged where needed. This version of the body was dubbed, the MK III.
The Shadow team mimicked the design of the McLaren M20 of the prior year by moving the radiators to the side of the car and placing wings between the front wheels. To gain an advantage against their competition, the team began experimenting with forced induction. The turbocharger system never made it past the experimentation stage.
The 1972 season was similar to the 1971 season. Oliver was able to finish only one race. The race he did finish, he crossed the line in third place just as he had done the year prior.
By this time the Shadow team had begun competing in Formula One Competition. Their entry into the series was the DN1, 'DN' for Don Nichols initials. The car had been designed by Tony Southgate. The DN1 gave Jean-Pierre Beltoise a victory at the Monaco Grand Prix. For the 1973 season, the team created the DN2 for CanAm competition. Southgate designed the car and drew inspiration from the Lola T310.
When the Shadow DN2 made its racing debut, it was powered by a 1200horsepower Chevy V8 engine. This massive amount of horsepower was generated with the help of a turbocharger. The system was used for three races and then switched for a naturally aspirated unit. The use of turbochargers had not worked well; in naturally aspirated form the Chevy V8 produced 735 horsepower which was enough to keep the car on pace.
The team finished the season in better standing then they had done in years past, but no where near what they had wanted to accomplish. The team finished only two races out of the eight that they entered. One was at Edmonton where the team finished in third and a second place at Laguna Seca. The team had been plagued by mechanical issues.
For 1974, Shadow entered their newly created DN4. It was very similar to the DN2 but smaller and lighter. Rule changes required the cars to get 3 mpg so the reduction in weight and size was done in an effort to comply with these new regulations. There were two cars; both were powered by Chevrolet V8 engines that produced an impressive 800 horsepower. Jackie Oliver drove one of the DN4 racers and George Follmer drove the second DN4.
1974 was a very successful season for the Shadow team. Follmer finished in second place in three of the races. Oliver won four races and went on to secure the championship. It should be noted that McLaren, Porsche and Lola had retired from competition and did not field new race cars for the 1974 season. 1974 also marked the final year for the CanAm series.
The Shadow team switched their attention to Formula One competition. They were met with little success and went out of business during the early 1980's. The company was absorbed by Theodore Racing. Lack of money meant that the team only lasted half-way through the season. Prior to the company's demise, a few members had left to form the Arrows F1 team. Alan Jones had left to work with Williams.

Heading into 1972, the team's original design was reworked and improved substantially. This was helped to some degree by the fact it was a titanium car. By 1973, Shadow grew to be one of the more competitive teams in the dying series of Can-Am racing [Read More...]
