The car split in half with the cockpit flipping several times. Andretti was extracted from the car and suffered only a fractured metatarsal bone in his left foot. 49 year-old Unser appeared headed to his first Pocono 500 win since 1978 until he suffered ignition failure while leading with 28 laps remaining. Unser had led

165-496: A privateer-engine supplier. As a result of Jack Brabham's long-standing relationship with Honda , Judd was hired by them to develop an engine for the company's return to Formula Two in association with Ron Tauranac 's Ralt team. After the demise of Formula Two at the end of the 1984 season, Judd continued to develop new engines for Honda. The first was the Judd AV, a turbocharged V8 engine built for Honda's CART campaign. It

220-567: A race-high 79 laps. Bobby Rahal assumed the lead after Unser's retirement. He led the final 28 laps and beat Al Unser Jr. by 17 seconds. The race was slowed by 11 cautions for 65 laps. Rahal's average speed was 133.713 mph, the slowest average speed in 18 races at Pocono. It was the first and only Indy car win for the Judd engine. It was the only race in the 1988 CART season that the Ilmor Chevrolet Indy V-8 didn't win. Criticism of

275-470: A third at the season finale at Miami. The engine became known for its reliability and superior fuel mileage (particularly in the 500-mile races). However, it was at a decided power disadvantage compared to the top engine of the time, the Ilmor-Chevrolet . In 1988, Truesports with driver Bobby Rahal took over as the primary team, and the "Honda" name and support was dropped from the powerplant. During

385-576: The 1988 season , Rahal took advantage of the engine's reliability in the 500-mile races, finishing fourth at Indy and second at the Michigan 500 . He then scored the first and only Indycar victory for the Judd engine, at the 1988 Pocono 500 . His ten top-10 finishes led to a third-place finish in the season points standings. Judd continued to build upgrades to the AV into the early 1990s, even after Honda had stopped badging

440-597: The 2004 24 Hours of Le Mans . It also won the LMP2 class championship in the ALMS in 2005. Both victories were for Intersport Racing, installed at the back of their Lola B2K/40. In 2002, Judd introduced a variant of the GV4 known as the GV5. The engine capacity increase to five litres was an attempt to reduce rpms, increase torque, and increase reliability. The GV5 quickly proved its superiority over

495-700: The Judd engine in Indy car racing. It was also the last win for the Truesports team. Rick Mears won his third Indianapolis 500 in May. Danny Sullivan won the Michigan 500 . The 1988 CART Season was dominated by the Ilmor Chevrolet Indy V-8 engine. The first nine races were won by the Chevrolet engine while Cosworth and Judd were winless entering the Pocono 500. During practice on Thursday, August 18, Mario Andretti posted

550-567: The San Marino Grand Prix . Judd's agreement with Scuderia Italia ended following the 1991 season, leaving the GVs to be used by the Brabham team and newcomers Andrea Moda Formula in 1992. Neither team scored a point all season and Judd Engines pulled out of Formula One. Following Judd's withdrawal from Formula One in 1992, John Judd turned to Yamaha to continue production of his engines. Using

605-546: The (mostly smaller) teams competing to the new rules. The first Formula One engine developed by Judd, the CV, was built to the 3.5-litre engine formula for naturally aspirated engines .

660-572: The 1989 season, Judd developed the all-new narrow-angle Judd EV, with a more compact 76-degree V angle, rather than the more conventional 90 degrees of the Judd AV/BV/CV, and the Cosworth DFV series. Construction of the CV continued as a cheaper alternative for smaller teams. Team Lotus and EuroBrun were the only CV customers, with Lotus finishing sixth in the Constructors' Championship. EuroBrun

715-584: The 3.4-litre layout but included technology developed from the GV series of engines to increase revs and performance while reducing weight. The XV675 debuted in 2004 with mixed success. Ray Mallock Ltd. earned the XV675 one of its few successes, winning the LMP2 class at the 2005 24 Hours of Le Mans , but the team later switched to the Advanced Engine Research turbocharged LMP2 engine which had become dominant in

770-841: The 4-litre version. The engine made its race debut in April 2013 at the Hockenheim circuit in Germany, scoring a double victory on its debut. The engine was expertly installed in the Benetton chassis by Kevin Mansell. Further success has followed in the 2014 , 2015 and 2016 seasons . In 2001, the Automobile Club de l'Ouest (ACO), organisers of the 24 Hours of Le Mans, announced new regulations for Le Mans Prototypes . The smaller LMP675 category would allow naturally aspirated V8 engines up to 3.4 litres. Using

825-613: The 600 bhp (447 kW; 608 PS) Judd V8 was commonly the fastest of the non-turbo engines, and the Marches of Ivan Capelli and Maurício Gugelmin regularly recorded higher speeds through the speed trap than the Cosworth DFR - and DFZ -powered cars with Gugelmin recording the fastest "atmo" speed trap of the season when he hit 312 km/h (194 mph) during qualifying for the German Grand Prix at Hockenheim (though this

880-470: The GV10 from a few years earlier. Expanded to four litres and upgraded with new technology, the new GV4 became a favorite choice for teams not running the dominant Ferrari 333 SP , eventually winning the championship with Racing for Holland in 2002 and 2003. In 2000 a Doran Ferrari 333 SP-Judd hybrid appeared, the performance of the Judd engine being deemed superior to that of the six-year-old Italian unit, which

935-558: The GV4, when it took second place in the teams' championship in the Rolex Sports Car Series in its debut year with Doran. Pescarolo Sport later went on to finish fourth at the 2004 24 Hours of Le Mans with a GV5. The following year, Pescarolo finished in second place at Le Mans and won the teams' championship in the Le Mans Endurance Series . The GV5 received an upgrade in 2006, using lighter materials to decrease

990-464: The HV) reduced to 3 litres, although the architecture of the engine was generally the same. Tyrrell's performance fell off again however, as the team scored five points and finished eighth in the championship. 1996 saw the same points total from Tyrrell, although the new Yamaha OX11 (Judd JV) engine was an all-new design. After 1996 Tyrrell switched to using Ford-branded engines. An updated C-Spec version of

1045-556: The Judd GV V10 as a base, Yamaha developed an all-new cylinder head and branded the motor as the OX10, for use by Tyrrell Racing in 1993 . Once again, Tyrrell were unable to score any points all season. An improved OX10B for 1994 boosted Tyrrell's performance, as the team scored a podium and finished sixth in the Constructors' Championship. Rule changes in 1995 saw the OX10C (known by Judd as

1100-612: The Judd GV5.5 S2. In an attempt to displace Ford and Cosworth as the only supplier of engines in the Champ Car World Series , Judd proposed a variant of the KV675 for use in the series through an agreement with MG, who would badge the engine. The deal did not come to fruition, but the development work performed based on the KV675 to adapt it to Champ Car was transferred to sports car racing. The improved engine, known as XV675 , retained

1210-597: The OX11 was used by Arrows in 1997 . Featuring a new bottom end, with changes consisting of a revised sump, crankshaft, oil pump and water pump; the OX11C had an extremely low centre of gravity (and a dry weight of 105 kg vs the Renault RS09's 121 kg) but was underpowered (708 bhp vs the RS09's 755 bhp) and most of all unreliable. Consequently, a D-Spec was introduced for

1265-625: The back of the numerous Lola B08/80 LMP2 cars in the LMS championship where it competes against the Zyteks and the rare Porsche RS Spyders . In 1997, Engine Developments was chosen by Nissan Motors to lead their engine development program on the Primera for the British Touring Car Championship . Nissan went on to win the constructors' championship in 1998 and 1999, with Laurent Aïello winning

1320-455: The class. It was used until 2008. On September 12, 2007, Engine Developments announced their plans for a replacement for the XV675, termed the DB. Although it retained the 3.4-litre engine capacity, the unit was entirely new. Judd planned to work closely with a top LMP2 team in order to get better testing out of the DB in 2008 before the engine was released to any customers. The engine is now found at

1375-561: The command to start engines in Polish and English. The pace car was a custom Ferrari Mondial built at a cost of one million dollars as a gift to series sponsor, PPG . It was driven by Kevin Cogan who was missing the race due to a broken left forearm suffered at Toronto in July. Polesitter, Rick Mears held the lead on the start. On lap two, the caution came out when Dick Simon's engine started smoking. On

1430-565: The design of the Formula 3000 KV V8, Judd expanded the engine to the maximum of 3.4 litres and reinforced it for endurance racing , creating the KV675. In its debut year, the KV675 won the LMP675 championship in the American Le Mans Series for Dick Barbour Racing. However, factory-supported efforts by MG and then Zytek were the dominant efforts in LMP675, so the KV675 only won its class at

1485-530: The driver's title in 1999. As part of MG's involvement with Judd elsewhere, the two worked together on MG's return to the British Touring Car Championship in 2004. Judd developed the K2000 engine for the MG ZS , with Anthony Reid finishing fourth in the driver's championship in their debut year. However, MG's financial troubles forced the company to drop out of the championship soon after, leaving

1540-584: The endurance requirements necessary in the World Sportscar Championship. As financial troubles hit other teams, the Judd V10 became one of the few privately funded engines for the top C1 class. Mazda was forced to turn to Judd to replace their outlawed rotary engines, although the GV10s would be rebadged as Mazda MV10s. Euro Racing, also purchased GV10s for their Lola T92/10s . Mazda finished third in

1595-474: The engine RPMs had to be reduced to ensure it survived the race. The 4.2-litre GV V10 engine was designed and developed for the 2013 season as a result of the remarkable success of the GV4 engine in the Boss series. Compared to the 4.0-litre GV V10 engine, the 4.2-litre GV V10 has been modernized; with lighter cylinder heads, twin-barrel throttles, and a lower centre of gravity. The engine is also 10 kg lighter than

1650-585: The engines that every Formula 3000 team used, although Zytek was tasked with maintaining the over 80 engines after they were built. Judd stopped production of the KV and the Formula 3000 series ended in 2004; contrary to rumour, Zytek did not use the KV engine as a basis for the A1 Grand Prix units in 2005, but used their own V8 designed by ex-Judd engineer Hiro Kaneda. In 1988, in conjunction with March Engineering , Judd made

1705-479: The engines. When Honda moved into the new Formula 3000 series, Judd again developed the company's engine. Based on the architecture of the AV, the new BV V8 was a naturally aspirated variant, and would eventually form the basis for the Judd CV Formula One engine. After the company's departure from Formula One, Judd returned to Formula 3000 in 1995 with the development of the 3-litre KV V8 engine. Judd built

1760-408: The fastest speed at 199.358 mph. Derek Daly was second fastest at 196.083 mph. Phil Krueger and Rich Vogler crashed in turn one in separate accidents but the cars were repaired. An estimated 10 tires were cut during practice, blamed on Pocono's boiler-plate metal wall that did not sit flush with the asphalt surface like a concrete wall. Debris was able to get under the wall and roll onto

1815-430: The first two laps. Tommy Byrne took the lead on lap three. Michael Greenfield , in a car co-owned by Chip Ganassi and Pat Patrick , took the lead on lap eight and led for the next 29 laps. A spin by Beekhuis and Mike Snow set up a four-lap run to the finish. On the restart, Byrne passed Greenfield entering turn one and pulled out to a sizable lead. On the final lap, Byrne caught a slow car in turn two and had to let off

1870-591: The fourth race, at Imola , with significant improvements in the airflow management of the combustion chamber area, which permitted the OX11D to gain 20 hp, which along with superior Bridgestone tyres propelled Damon Hill to a second place at the Hungaroring , the 11th race of a year that otherwise was pretty lacklustre with Pedro Diniz 's 5th place at the Nürburgring as a last high point before Yamaha consequently pulled

1925-412: The lead on lap 87. It was the first time Foyt had led multiple laps in an Indy car race since Michigan in July 1984. Foyt led 14 laps before gearbox issues put him out after 132 laps. It was the last time he would lead an Indy car race. On lap 117, Dick Simon and Mario Andretti collided entering turn three. Simon, who was 18 laps down, failed to see Andretti passing inside and cut him off. The two cars hit

1980-446: The move into the recently reintroduced normally aspirated variant of Formula One , which would completely replace turbocharged cars in 1989. By using the existing BV V8 as the starting point for their new F1 engine, Judd saved cost while at the same time producing a customer engine that could compete on track and in the marketplace with the Ford - Cosworth V8s that were standard equipment for

2035-579: The plug on the failing project. ( key ) (Races in bold indicate pole position) (Races in italics indicate fastest lap) In 1991, the World Sportscar Championship introduced an engine formula nearly identical to Formula One. This was an attempt to decrease cost by allowing sportscar teams to purchase Formula One engines, while at the same time encouraging major sportscar manufacturers to enter Formula One. This allowed for Judd to offer their GV V10 to customers following modifications to meet

2090-441: The restart, Danny Sullivan took the lead. Before one lap was completed, Arie Luyendyk crashed in turn three. He was hospitalized for a fractured right heel. On lap 28, Michael Andretti blew an engine and brought out the third caution. Sullivan pitted after the restart, which gave the lead to Al Unser . Phil Krueger crashed after completing 42 laps. Rick Mears hit debris and damaged his suspension. 53 year-old A. J. Foyt took

2200-548: The team's championship while Euro Racing took fifth. The World Sportscar Championship was cancelled in 1993, quickly ending Judd's first brief involvement in sports car racing. After engine involvement with Yamaha in Formula One, Judd returned once again to sports car racing. Believing that a large naturally aspirated engine would be fitting for use as a customer supply in the Sports Racing World Cup , Judd resurrected

2255-466: The throttle, allowing Greenfield to catch and pass him. It was Greenfield's first win in the series. A 24-lap, 60 mile race for the SCCA RaceTruck Challenge was held on Saturday afternoon. 19 year-old actor, Jason Bateman , was making his second start in the series, driving a Mitsubishi Mighty Max . On lap one, polesitter, Richie Agresti spun in turn two. Agresti slid across the track and

2310-499: The track conditions became more vocal in 1988. Drivers were upset with the bumpy and weathered asphalt and openly hoped that the track would be repaved. Race-winner Rick Mears said "this is a great place to come to race, provided they do resurface it. The drivers think it's a fun track, a great track." Danny Sullivan said, "It would be nice if they would resurface it like they're doing at Indianapolis now." Emerson Fittipaldi said, "If you want my opinion, we shouldn't run here. The surface

2365-423: The track. Andretti was quoted as saying, "if you had a concrete wall, you wouldn't have that problem." In Friday morning's practice, Rick Mears posted the fastest speed at 205.761 mph. Early in the afternoon qualifying session, Danny Sullivan posted a speed of 203.358 mph. Sullivan's time was the fastest until Rick Mears went out late and took pole position with a speed of 204.564 mph. Bobby Rahal

2420-576: The wall, collecting Danny Sullivan who wrecked trying to avoid the debris. The 54 year-old Simon was heavily criticized by both Sullivan and Andretti, who suffered a bruised right thigh. "He was in the way all day," Andretti said. "He should be more concerned with the leaders. He should not be running, in my opinion." Sullivan asked, "How many times does he have to cause something like this before someone realizes that something has to be done?" Simon only drove one more Indy car race before retiring. During green flag pit stops on lap 168, John Andretti broke

2475-524: The weight of the unit by 20 kg. The GV5 S2 showed its performance by taking the Pescarolo to second place once again at Le Mans behind Audi 's R10, as well as winning every event in the Le Mans Series season. The engine was further upgraded in 2007, with an increase in displacement to 5.5 litres to produce more torque while attaining the maximum power at lower rpms and improving fuel consumption, as

2530-410: Was disqualified due to the rear wing being set back too far. Krueger was allowed to start the race with a promoter's option. Dale Coyne qualified at a speed of 167.835 mph. He was not allowed to start the race because his speed did not meet CART's rule that all qualifiers must be within 115% of the pole speed. The 40 lap, American Racing Series event was held on Saturday. Jon Beekhuis led

2585-555: Was first used on the CART circuit midway through the 1986 season , fielded by Galles Racing and driver Geoff Brabham . It was initially badged as the Brabham-Honda , and scored a fourth-place finish at the 1986 Michigan 500 . In 1987 , the engine was used for the first time at the Indianapolis 500 . Brabham scored second-place finishes in 1987 at Pocono and Road America , as well as

2640-438: Was hit hard by Bateman in the left front. Bateman's truck got airborne and landed on its roof. The impact pushed the left-front wheel back into the cockpit and broke Bateman's left ankle. Driving a Jeep Comanche , Al Unser led the first seven laps before dropping back to 19th. Tommy Archer beat his brother Bobby by 0.06 seconds to win the race. Sławomir Wałęsa, the 15-year-old son of Polish statesman Lech Wałęsa , delivered

2695-404: Was later forced also to turn to Judd, after they lost their supply of Honda engines for 1988. In addition, Ligier also bought CVs for use in the 1988 season. Judd-powered cars finished in podium positions four times during their debut season, with Williams' lead driver, Nigel Mansell , scoring Judd's first podium when he finished second at the 1988 British Grand Prix . During the 1988 season,

2750-520: Was no longer supported by Ferrari. The GV4s also became powerful enough to contest for overall wins in the 24 Hours of Le Mans , with Oreca Dallaras running the GV4 finishing fifth and sixth in 2002 as well as an overall victory for Doran Lista at the Rolex 24 at Daytona the same year. The engine's reliability record at Le Mans was still patchy and, while it could challenge for the pole in Domes and Dallaras,

2805-507: Was originally the only team to continue with the CV unit into 1990, but Life eventually bought CV units to replace their failed in-house W12 engine design. The previous Judd CV was designed with a conventional 90-degree engine block. Following the 1988 season it was decided that a narrower vee-angle would be adopted to give a more compact engine; the original intent was a 75-degree vee, but limitations in Judd's CNC equipment (it could only work in even-degree increments) meant that 76 degrees

2860-508: Was still considerably slower than the turbo-powered McLaren - Hondas which were timed at 333 km/h (207 mph)). At the 1988 Japanese Grand Prix Capelli's Judd-powered March 881 became the first naturally-aspirated car to lead a lap of a Grand Prix since 1983 , when he briefly passed the McLaren of two-time World Drivers' champion Alain Prost for the lead on lap 16 of the 51 lap race. For

2915-463: Was the only team to use the older EV. In the normally aspirated 3.5 litre formula, ten and twelve cylinder engines had proved to be more powerful than V8s. This prompted Judd to replace the CV and EV V8s with an all-new engine in 1991 for the BMS Scuderia Italia team. The new 72-degree angle V10 engine would carry the GV name. The engine was powerful, helping the team to a podium finish in

2970-408: Was third fastest at 202.520 mph. Rick Mears became the first driver to win the pole for all three 500 mile races in a single season. 1983 Pocono 500 winner, Teo Fabi , crashed on lap one of his qualifying run when he ran wide in turn three and hit the wall. He went to a backup car and qualified on Saturday. In Saturday's qualifying session, Phil Krueger posted a speed of 187.825 mph, but

3025-534: Was used instead. March Engineering upgraded their 1988 CV unit to an EV in 1989, while Brabham was also supplied with the new engines. Brabham and March each scored one podium with the EV engine. Both teams continued with the EV in 1990, although March Engineering was renamed Leyton House Racing . Leyton House took the engine's only podium of the season, a second place at the French Grand Prix . For 1991, Team Lotus
