1949 Kurtis/Deidt-Offenhauser FWD Special

Offered by RM Sotheby’s | Monterey, California | August 17-19, 2023

Here’s a handful of names that once dominated at Indianapolis: Frank Kurtis, Emil Deidt, Fred Offenhauser. Combining all three into one car? Should be pretty special. And that’s kind of what happened here.

So, what happened here was: owner Gil Pearson commissioned Deidt to build two front-wheel-drive race cars. Frank Kurtis built the body and frame, and then they stuffed a 4.4-liter Meyer-Drake-Offenhauser inline-four up front to drive the front wheels. They took it out to the Muroc dry lake bed and hit 176 mph.

It was then used in some movies before being parked with its sister car behind Gil Pearson’s house until the 1990s. It was then restored before being invited to Pebble Beach in 2001. Now it has a pre-sale estimate of $350,000-$500,000. Click here for more info.

Update: Not sold.

1996 Champ Car

1996 Reynard 96I

Offered by Mecum | Monterey, California | August 17-29, 2023

This is what race cars are supposed to look like. Team Rahal Reynards. The main chassis producers for the 1996 Champ Car season were Reynard and Lola. Team Rahal ran Reynard 96Is for Bobby Rahal and Bryan Herta, the latter of whom drove the Shell-liveried car you see here.

Back in the day, these were powered by a Mercedes/Ilmor 2.7-liter V8. This one is currently engineless. Unfortunately no competition history is provided for this chassis, but the catalog insinuates (a bit disingenuously) that this was the car involved in “The Pass” by Alex Zanardi at Laguna Seca.

Anyway, even without an engine this remains a fine example of the glory days of Champ Car. It has an estimate of $50,000-$80,000, and you can find out more about it here.

Lotus 107C

1993 Lotus 107C

Offered by Bonhams | Goodwood, U.K. | July 14, 2023

Lotus has a long history in F1. From the days of Colin Chapman and Jim Clark to dominance in the ’70s and Mario Andretti’s only F1 championship. Lotus survived into the ’90s, selling out to what would become Pacific Racing, a team that disappeared after one season. The name then returned in the 2010s for a few years, which basically a holding place after Renault left and before they returned again.

Anyway, the Type 107 was designed by Chris Murphy (and team) and debuted for the 1992 season. The car was updated to “B” spec for 1993 and then to “C” specification for the first half of 1994 before it was replaced by the 109. Power in period was from a Ford-Cosworth V8 in ’92 and ’93 and a Mugen-Honda 3.5-liter V10 in 1994. Output was 725 horsepower for the Honda.

The history for this chassis, 107C-01 includes:

  • 1994 Pacific Grand Prix at Aida, Japan – 8th (with Pedro Lamy)
  • 1994 San Marino Grand Prix – 10th (with Johnny Herbert)
  • 1994 Monaco Grand Prix – 11th (with Lamy)

Lamy then used this car in testing at Silverstone when it suffered a catastrophic failure and was essentially destroyed. After Team Lotus failed in 1995, the remnants of this chassis were purchased by the current owner in 1997 along with some spares and rebuilt to show-car status. The Mugen-Honda V10 is long gone, but a mocked-up Judd V10 without internals is in there. The estimate is still $90,000-$125,000. Read more about it here.

Update: Sold $124,208.

Tyrrell 014

1985 Tyrrell 014

Offered by Bonhams | Goodwood, U.K. | July 14, 2023

Tyrrell was an innovative F1 team, especially in the 1970s. Ken Tyrrell started campaigning cars in other Formula in the late 1950s, arriving on the F1 scene in 1966. The team’s peak occurred in the late 1960s and early ’70s. Their final win came in 1983, and the mid-1980s were not kind. Their last season was 1998 before being bought by BAR, which became the Honda F1 team.

The 014 was the replacement for the 012 (which was a car that got Tyrrell disqualified from the 1982 championship season). The 014 was used for the latter half of the 1985 season and the first few races of 1986. The team’s drivers during that span consisted of Martin Brundle, Stefan Bellof, Ivan Capelli, and Philippe Streiff.

This car was raced with power from a Renault-Gordini turbocharged 1.5-liter V6. Only four 014 chassis were made, and the history for this one, 014/3, includes:

  • 1985 Italian Grand Prix – 8th (with Martin Brundle)
  • 1985 Belgian Grand Prix – 13th (with Brundle)
  • 1985 European Grand Prix at Brands Hatch – 18th, DNF (with Brundle)
  • 1985 South African Grand Prix – 7th (with Brundle)
  • 1985 Australian Grand Prix – 13th (with Brundle)
  • 1986 Spanish Grand Prix – 10th, DNF (with Brundle)

This car is described as being “in as-last-raced condition” and does not have an engine. But the gearbox is there! So you can sit in it and pull through the gears making revving noises. The estimate here is $63,000-$100,000. Click here for more info.

Update: Sold $73,933.

Koenigsegg GT1

2007 Koenigsegg CCGT GT1

Offered by Bonhams | Goodwood, U.K. | July 14, 2023

The Koenigsegg CCX was introduced in 2006 as the company’s third-ish model. The company decided they wanted to go GT racing around this time, so they developed this, the CCGT GT1. It was aimed at the FIA’s GT1 class in their GT Championship. This would’ve put it up against the likes of Chevy’s C6.R, the Aston Martin DB9R, and the Maserati MC12 GT1.

It’s powered by a 5.0-liter V8 that made over 600 horsepower. It also had a carbon-fiber monocoque – which the FIA outlawed for the upcoming season shortly after this car debuted, thus rendering it illegal and immediately obsolete. The FIA also then stipulated that 350 road cars had to be produced to homologate the car for racing. I’m not sure Koenigsegg has produced 350 cars to date, total. It’s like the FIA wants to keep their fields small and uninteresting.

So this was the only example built. One of Koenigsegg’s shareholders took the car home, and has had it ever since. Now it’s coming up for sale for the first time with an estimate of $3,750,000-$5,000,000. More info can be found here.

Update: Sold $4,267,570.

Nissan R90CK

1990 Nissan R90CK

Offered by Artcurial | Le Mans, France | June 30, 2023

Nissan’s Group C program gave us some pretty spectacular prototype race cars. Especially those in their red, white, and blue livery. The R90C was their car for the 1990 World Sportscar Championship season, and there were a few subvariants.

This is an R90CK, which featured a low nose and two massive inlets up near the base of the cockpit. It’s powered by a twin-turbocharged 3.5-liter V8 that could produce up to 1,000 horsepower in qualifying trim. This chassis is the last of 13 R90C cars built and is one of six of the R90CK variety. The race history for this chassis, #07, includes various races in the All Japan Sports Prototype Championship in addition to the:

  • 1992 24 Hours of Daytona – 8th (with Volkert Weidler, Mauro Martini, and Jeff Krosnoff)
  • 1993 1,0000km Suzuka – 2nd (with Martini and Heinz-Harald Frentzen)

For that last one, the car had been upgraded to R93 specification, but afterward Group C was pretty much done. The car was put away for about a decade before being purchased by someone looking to race it in historic events. It now has an estimate of $550,000-$875,000. Click here for more info.

Update: Sold $587,060.

Porsche 910

1967 Porsche 910

Offered by Bring a Trailer Auctions | June 2023

If only Porsche went in order with their model name/numbering scheme. That would make the 911 the follow up to this, the 910. Imagine what a street-legal follow up to this car would’ve looked like. Instead, they are entirely unrelated.

The 910 was an evolution of the earlier 906 and for some reason slotted in between the 906 and 907 in terms of P-car prototype racers. The 910 was produced in 1966 and 1967. Just 27 were built, and this one was never raced under the Porsche works factory banner. It was used as an R&D car before being sold into private hands and later raced, including at the:

  • 1973 24 Hours of Daytona – 38th, DNF (with Ed Abate and Bill Cuddy)

It is powered by a 2.0-liter flat-six that made around 200 horsepower. At one point during its life it had a 2.2-liter flat-eight installed that made closer to 300 horsepower. That engine, which is extremely rare and valuable on its own, is included in this sale. This car was recently repainted and was previously used on European tours (so there’s a hope of getting it road registered). You can read more about it here.

Update: Sold $2,500,000.

Saleen S7-R

Boutique supercar manufacturers sometimes (and rightly so) feel the need to prove their cars at the track. It doesn’t happen all that often anymore, as the cost of entry with a halfway-decent GT-class entry at Le Mans is usually prohibitive for start ups. But that didn’t stop companies like Lister, Spyker, Saleen, and others from giving it a go.

Saleen’s S7 was sold between 2000 and 2009. The racing variant, the S7-R (and not the S7 LM, which is a re-launched road car) was produced until about 2008. Initial cars were built by Ray Mallock Ltd before Saleen took over production, with the final prep work being done by Oreca. This is the final of 23 example built, and it is powered by a 7.0-liter V8 that made 600-760 horsepower depending on the state of tune.

The competition history for this chassis,082, includes:

  • 2009 1000km Nurburgring – 23rd, 1st in class (with Roland Berville, Sebastien Dumez, Laurent Groppi)
  • 2010 1000km Spa – 31st (with Gabriele Gardel, Patrice Goueslard, and Fernando Rees)
  • 2010 24 Hours of Le Mans – 13th, 1st in class (with Berville, Gardel, and Julien Canal)

After that, the car remained with its campaigner: French racing team Larbre Competition. And that’s who is selling it. You can read more about it here.

Update: Sold $1,421,287.

Spyker C8 GT2-R

Offered by RM Sotheby’s | Le Mans, France | June 9, 2023

Ferrari might have “Scuderia Ferrari” but aircraft-themed company Spyker had the best factory racing team name of them all: Spyker Squadron. Spyker competed at the 24 Hours of Le Mans from 2002 through 2010, only missing the 2004 race. They entered their C8 sports car in the GT2 class.

What’s even cooler is that their second GT2 car was actually based on their Spyder road car. Meaning it was essentially an open-cockpit race car. Because why not. Power is provided by a 3.8-liter version of Audi’s V8, with output somewhere around 450 horsepower. The competition history for this chassis, 3046, includes:

  • 2005 12 Hours of Sebring – 31st, DNF (with Tom Coronel, Donny Crevels, and Marc Goossens)
  • 2005 24 Hours of Le Mans – 40th, DNF (with Coronel, Crevels, and Peter van Merksteijn)
  • 2006 12 Hours of Sebring – 18th (with Jeroen Bleekmolen and Mike Hezemans)
  • 2006 1000km of Spa – 38th, DNF (with Crevels and Jonny Kane)
  • 2006 1000km of Nurburgring – 20th-ish, DNF (with either Coronel or Crevels and Kane)

Spykers are weird. And that’s part of what makes them cool. They are also art. And the fact that the company decided to actually take that art racing? Awesome. Read more about this car here.

Update: Sold $307,101.

Jaguar XJR-12

1991 Jaguar XJR-12

Jaguar got into Group C early, and by 1990, they were on the XJR-12, which when fielded by the factory, wore Silk Cut liveries. The cars were introduced in 1990 and some competed in 1991 and 1992 before being supplanted by the XJR-14.

This chassis was built new for 1991. While the 1990 cars were powered by 7.0-liter V12s, the 1991 cars were powered by 7.4-liter V12s, which presumably made more power than the 730-horsepower, 7.0-liter units. The XJR-12 won the 1990 24 Hours of Le Mans. The competition history for this chassis, J12C-891, includes:

  • 1991 24 Hours of Le Mans – 4th (with Derek Warwick, John Nielsen, and Andy Wallace)
  • 1992 24 Hours of Daytona – 2nd (with David Brabham, Scott Pruett, Scott Goodyear, and Davy Jones)
  • 1992 12 Hours of Sebring – 4th (with Brabham and Jones)

…a fairly successful run. This car remained with Tom Walkinshaw Racing until being purchased by its current owner in 2017. It’s been used at the Le Mans Classic and is ready to go. Click here for more info.

Update: Not sold.
