Film: The Spark Plug Story

This short film offers an excellent 15 minute history lesson into one of the internal combustion engine’s simplest but most important parts: the humble spark plug.

The first patents for what we would today call a spark plug were filed in 1898 by Nikola Tesla, Robert Bosch, and Frederick Richard Simms, however the invention of the spark plug is widely attributed to Étienne Lenoir.

The name Étienne Lenoir is probably already familiar to you as he was the Belgian-French engineer who developed an internal combustion engine design that used a spark plug back in 1858.

The internal combustion engine itself was invented by the Franco-Swiss inventor Isaac de Rivaz back in 1804, however it was the Lenoir design that would develop the ancestor of the engines we use today.

This film does an excellent job of charting the history of the spark plug and tracking its development changes over the years.

Spark plugs themselves have outwardly looked quite similar for over 100 years, with early designs looking like short stubby versions of modern plugs, but internally the materials and construction has completely changed over that time.

The Dodge Firearrow II: A Highly-Influential 1950s Concept Car

The Dodge Firearrow II was one of four influential concept cars built by Italian coachbuilders Ghia under the direction of Virgil Exner, one of the most celebrated (and most copied) American car designers of the mid-20th century.

Unlike the earlier Dodge Firearrow I which was a static model for display only, the Dodge Firearrow II was a fully functioning and drivable car built as a potential precursor to a production run.

Sadly the production run would never get the green light, leaving the Firearrow I, II, III, and IV, as the only examples of what might have been.

Fast Facts – The Dodge Firearrow II

  • The Dodge Firearrow II was built in 1954, it has a body made by hand in Italy by the craftsmen at Ghia, and it rides on a 119 inch Dodge wheelbase.
  • Power is provided by a 241 cubic inch, 150 hp “Red Ram” Hemi V8, and power is sent to the rear wheels via a Gyro-Torque 4-speed automatic transmission.
  • The styling of the Firearrow concept cars was revolutionary for the time, and some styling elements would make it into production cars, however the Firearrows themselves never made it to production.

Virgil Exner And The Forward Look

The Firearrow program was run by automotive styling icon Virgil Exner, who is perhaps best known for the “Forward Look” design program he launched in 1955.

Above Image: The styling of all four Firearrow cars would have a notable influence on other car designs from the manufacturer throughout the 1950s.

His designs included the use of tail fins, which he wind tunnel tested at the University of Michigan, he also preferred lower rooflines and he created sleeker, more modern “slab side” designs that helped set the Jet Age styling trend in motion.

Exner’s early life had been dominated by his fascination with both art and automobiles, two passions that would guide the course of his entire life. As a young man he was hired by General Motors styling legend Harley Earl and before he turned 30 he was already in charge of Pontiac styling.

Just before the onset of World War II Exner joined Raymond Loewy’s industrial design firm, Loewy and Associates, where he would spend much of the war designing both military vehicles and cars for eventual post-war production.

Exner Moves To Chrysler

In 1944 he joined Studebaker where he penned the 1947 Studebaker Starlight coupe, then in 1949 he would make what was almost certainly the most important change of his career, when he started working at Chrysler’s Advanced Styling Group.

It would be at Chrysler, working alongside the likes of Cliff Voss, Maury Baldwin, and with Luigi “Gigi” Segre of Ghia, that Exner would make his biggest impact. It would be during this time that the four Dodge Firearrow concept cars would be released, from 1953 to 1954, before the famed Forward Look program kicked off in 1955, heavily influenced by the Firearrow vehicles.

In 1957 Exner and his team were given the prestigious Gold Medal Award by the Industrial Designers Institute (IDI), thanks largely to their Forward Look cars including the Chrysler 300 series and the 1955 Imperial series.

The Dodge Firearrow Concept Cars

The release of the four Firearrows in 1953 and 1954 signalled a new design direction for the company, and today the cars are each celebrities in their own right. The first of the cars, the Firearrow I, was a rolling display model that wowed crowds but was unable to be driven.

This all changed in 1954 with the Firearrow II, it was clearly influenced by the design of the earlier car but unlike its forebear it was 100% drivable and roadworthy, with a 241 cubic inch, 150 hp “Red Ram” Hemi V8 giving it plenty of power by the standards of the era.

The styling of the second car in the series would be closely based on its predecessor, the main differences were the change to two headlights rather than four, it had round taillights, chrome wire wheels, a new “toothed” grille, and trim that stopped at the sides, instead of wrapping around the front and rear of the car.

The “slab sides” of the car would become a feature on many new production cars, people have marveled over the frameless windscreen, the sleek rear fins, and the integrated quad exhaust tips for decades since the car’s introduction.

The Firearrow II would be followed by the Firearrow III, a hardtop couple, the and Firearrow IV which was described as being a production ready car – a good indication of just how close it came to car dealer floors.

The Firearrow II was restored to original condition in the 1990s when it was part of the concept car collection of Joe Bortz.

The car is now due to be offered for sale by RM Sotheby’s on the 13th of August with a price estimate of $900,000 – $1,200,000 USD. If you’d like to read more about it or register to bid you can click here to visit the listing.

For Sale: A Ford GT40 RCR Stunt Car From “Ford v Ferrari”

This is one of six GT40s built by RCR for the Oscar winning film Ford v Ferrari starring Christian Bale and Matt Damon. The car was built to 1966 Ford GT40 specifications for the movie with very close attention to detail.

Interestingly this is the only one of the six stunt cars that has a VIN and a title, meaning it can be road registered. The car is powered by a 5.7 liter V8, power is sent to the rear wheels via a 6-speed manual transmission and it was stickered No. 88 William Wonder for the 24 hours of Daytona scene in the film.

Ford v Ferrari would go on to be a major success for 20th Century Fox, earning almost a quarter of a billion dollars at the box office and receiving four Academy Award nominations – eventually winning two Oscars for Best Film Editing and Best Sound Editing.

Fast Facts – A Ford v Ferrari GT40 Stunt Car

  • The original Ford GT40 was developed by Eric Broadley and his team at Lola Cars in Britain with additional input from Ford.
  • The GT40 was developed with a single purpose in mind – to beat Enzo Ferrari at the 24 Hours of Le Mans and claim the world title.
  • The Hollywood film Ford v Ferrari is based around the battle between the two automakers, centering on the story of Carroll Shelby and Ken Miles.

The Ford v Ferrari Battle

The story behind the Ford v Ferrari film will already be a familiar to many classic car buffs, but to cut a long story short, Ford was in negotiations to buy Ferrari in 1963 as the Italian company was struggling. Enzo Ferrari used the impending Ford acquisition to negotiate a better deal with his Italian compatriots over at Fiat – a deal that allowed him to keep both ownership and control of Ferrari.

When Ford executives, including Henry Ford II and Lee Iacocca, realized they’d been used they formulated a plan to beat Ferrari where it would hurt most – at the world famous 24 Hours of Le Mans endurance race. Ferrari had won every 24 Hours of Le Mans race from 1960 to 1965, so beating them there would make headlines around the world.

How To Beat Enzo Ferrari

It would take a special car to beat Ferrari around the Circuit de la Sarthe in western France, the storied home of Le Mans. By the mid-1960s it seemed clear that for a car to be competitive it would need to be rear-mid engined, it would need excellent aerodynamics, and it would have to be capable of running flat out for 24 hours straight.

Ford didn’t have a car like this on hand, but an Englishman named Eric Broadley did. Broadley was the founder of Lola Cars based in England, and he had developed a car alongside John Frayling that just happened to be an aerodynamic, rear-mid engined endurance racer with excellent aerodynamics – it was called the Lola Mk6. Funnily enough it was already powered by a Ford V8.

The project to build the Ford GT40 was rapidly put into action, Eric Broadley agreed to work with the Americans on the project and he sold them two examples of the Lola Mk6. Former Aston Martin team manager John Wyer was brought onboard for the project, Wyer had guided the Aston Martin team to a Le Mans victory in 1959.

The final key addition to the project would be American engineer Roy Lunn who was sent over from Ford in the USA. Lunn had previously designed the rear-mid engined Mustang I concept car, and he was the only Ford engineer with experience working with this engine configuration.

The three men and their team rapidly developed the Ford GT40 chassis and body design, unveiling it only a year or so later in England followed by an exhibition in New York. Due in large part to the rapid development timeframe the 1964 year wasn’t successful for the GT40, there were many mechanical failures and other issues that eventually led to John Wyer being removed from the project (fairly or unfairly), and Carroll Shelby taking over.

Above Film: This is the official theatrical trailer for Ford v Ferrari.

Ford would get their Le Mans victories over Ferrari in 1966 and 1967, after this John Wyer would return and take over the Ford GT40 production facilities and the team would go on to win Le Mans twice more, in 1968 and 1969 – a final vindication for Wyer.

The Ford v Ferrari Stunt Cars

Given the subject matter, it was clear that Ford v Ferrari was going to require a number of GT40s for filming. It was also clear that the historic and monetary value of the original cars was going to be far too high for them to be used.

Fortunately there are a number of companies that build near-indentical replicas of the Ford GT40, including RCR (Race Car Replicas) of Fraser, Michigan. It would be RCR that were chosen to build many of the stunt cars for the film, they produced six in total and as mentioned above, the car you see here is said to be the only one with a VIN and a title.

This GT40 was named the Dan Gurney car as it was the No. 3 car used in the Le Mans race scene, it was also used for the 24 Hours of Daytona scene with a new No. 88 livery. Anyone who’s seen the film will have seen this car on screen being driven in anger.

The car is now due to roll across the auction block in early September with Mecum, there’s no price guide at the time of writing, and you can click here to visit the listing if you’d like to read more or register to bid.
