Sadly, no submarine options on this 1979 Lotus Esprit Group 5
Could 14th, 1978. On the disused aerodrome in Silverstone, England, Porsche unloaded one of many really legendary Group 5 vehicles ever created for its sole outing on British soil. Nicknamed after the tile of American novelist Herman Melville’s basic ’Moby Dick’, the automobile blitzed the sector in qualifying and gained by a humongous seven laps after six hours of racing. The German invasion left no room for any doubters because the cohort of Porsche 935s led by the Works-backed Martini whale proved unbeatable. Regardless of that, the turbocharged silhouettes from Stuttgart didn’t full the clear sweep. A 2.0-liter BMW with a 3rd of the ability of the Porsches got here dwelling third, albeit 16 laps adrift.
That BMW was certainly one of 5 entered within the 2.0-liter division of Group 5, also called Division II. The widebodied Bimmers ran unopposed leaving native followers dismayed. They’d been hoping that information of not one however a pair of Lotus Esprits being readied for the Silverstone spherical of the World Championship would show to have a minimum of a grain of reality in it. Sadly, these two vehicles, the No. 58 Macinnes Amcron Esprit of Ian Marshall and the No. 59 Morfe Racing with Polaroof Esprit of Richard Jenvey, by no means confirmed up. Let’s dial the clock again some 40 years and discover out what occurred with the Esprit Group 5.
Within the ’70s, the British racing scene was fairly full of life with a variety of widespread collection attracting large crowds and lots of vehicles on the grids. The British Saloon Automotive Championship (now generally known as the British Touring Automotive Championship or the BTCC) might have been the largest collection on the island however you additionally had stuff like Tremendous Saloons and the Modsports GT championship, each catering in the direction of closely modified production-based fashions. Richard Jenvey loved success within the latter collection, being topped champion of the 1975 season driving a Lotus Elan.
An engineer by commerce and a Lotus fan by coronary heart, Jenvey was impressed by Lotus’ brand-new sports activities automobile for 1976, the Esprit. Two years down the road, and with Group 5 changing into increasingly more widespread throughout Europe and world wide, he determined it’s time to go all in and have a stab at racing within the large league, the World Championship for Makes. His weapon of alternative? The glossy Esprit. On the time work began on the mission, Ian Marshall, one other useful sports activities automobile driver, was already engaged on a Modsports-spec Esprit however this didn’t cease Jenvey from getting in contact with Lotus boss Colin Chapman and ask for assist.
Richard says that Chapman wasn’t all that eager to assist out privateers making an attempt to construct a racing Esprit, reportedly hitting “the desk so arduous to emphasise a detrimental response that his espresso cup jumped off the desk,” when approached by Lotus’ Gross sales Director relating to Marshall’s Esprit construct. On the finish of the day, it seems that each Marshall and Jenvey acquired a serving to hand from Hethel.
In Jenvey’s case, this translated to a full automobile, particularly Esprit chassis #02, one of many take a look at mules that the corporate might do with out by ’78. It’s unclear whether or not or not the automobile was geared up with the two.0-liter, straight-four Kind 907 DOHC, all-aluminum engine however it’s clear the engine wasn’t going to chop it in a racing utility. Regardless of it that includes a pair of twin-choke Dellorto carburetors, output within the case of the Esprit S1 was an underwhelming 160 horsepower and 140 pound-feet of torque.
After receiving the automobile, Jenvey rapidly made some moulds of the physique panels and offered the physique off, protecting the chassis for his construct. On the finish of the day, the chassis was fairly radical with the entire again finish being taken nearly completely from a March F1 automobile, together with the suspension uprights and the Hewland FG400 gearbox, a $26,000 transmission on at present’s market. Utilizing the moulds, Jenvey made a wider rear deck and entrance nosecone that includes a lowered air dam. An aluminum lip was added in addition to a giant wing within the again.
It ended up wanting imply regardless of its diminutive dimensions (an Esprit solely measures 165 inches in size, some 18 lower than a 2020 Corolla) and Lotus aided Jenvey some extra when it got here to filling up the engine bay. A deal was struck with Vegatune to construct a 270-horsepower 2.0-liter mill with the Kind 907 block (some sources declare it raced with a Cosworth belt-driven inline-four however Richard confirms it was a Lotus block).
Whereas this was significantly greater than what the inventory engine might muster, it was nonetheless some 60 horsepower away from what BMW had.
The BMW 320i was powered by the tried and examined M12/7, a four-valve engine of F2 origin spinning at 10,000 rpm.
Not less than the 2 vehicles had been on par by way of weight, each tipping the scales at about 1,873 kilos which was the minimal weight for two.0-liter Group 5 vehicles.
Jenvey hoped to have the automobile prepared and on the grid in throughout 1978 and he even lodged a request with the ACO for a spot on the entry listing for that 12 months’s 24 Hours of Le Mans. However, because it usually is the case when constructing a automobile from the bottom up, all the staff’s estimations had been dashed as rapidly as Jenvey’s funds dried up. In the long run, the automobile turned a wheel for the primary time in April of 1979 on the Six Hours of Dijon-Prenois. By then, Marshall’s Esprit had already made its nationwide debut however, to Jenvey’s credit score, Marshall by no means raced within the World Championship along with his Group 5-esque Lotus wedge making the Morfe Racing with Polaroof automobile a singular effort in interval.
In its debut outing, the Lotus proved quick, out-qualifying the opposite 2.0-liter Group 5 vehicles by a snug margin to start out nineteenth total. Sadly, piston failure noticed the Lotus out by lap 19. Then, one 12 months later than initially deliberate, the Esprit lastly ran in anger at Silverstone. This time, nonetheless, a category pole was out of attain as Lancia’s factory-backed staff arrived from Italy with an impeccable Beta Monte-Carlo Turbo.
Narrowly overwhelmed by Robin Hamilton’s Aston Martin AM V-8, the Lotus solely needed to end the race to say class honors after each the Beta (pushed by Walter Rohrl no much less) and a BMW 320i retired.
Sadly, so did Jenvey’s Lotus, this time kneeled by distributor issues. The maladies hit throughout the second lap of the race when the automobile arrived at a snail’s tempo in entrance of its pit field. The enterprising staff managed to get the factor operating once more however it stopped quickly after someplace on monitor and was disqualified as a result of it acquired outdoors help. Not less than, Lancia’s monetary would possibly didn’t translate right into a extra respectable debut for its Beta Monte-Carlo. A head gasket blew after merely 4 laps to finish the day of the longer term world champions.
What adopted subsequent was one other irritating exhibiting on the Nurburgring. The staff didn’t qualify for the race as a consequence of gas vaporization points in observe. With reliability nonetheless not the place Jenvey would’ve wished it to be, one other version of the 24 Hours of Le Mans was additionally skipped and the automobile wouldn’t race once more till the Six Hours of Manufacturers Hatch in August (it additionally confirmed up on the Zandvoort DRM spherical however didn’t make it on the grid). At Manufacturers, the Esprit one way or the other managed to cross the end line pushed by Jenvey, David Mercer and Mike Chittenden however it wasn’t labeled as a consequence of extended delays.
Mercer, who in 1977 had pushed the ex-Jenvey Elan up to date to correct 2.0-liter Group 5 specification alongside Chittenden, was changed in 1980 by Lawrie Hickman. He was the protagonist of a clumsy incident throughout that 12 months’s Dijon Six Hours when he broke the gear linkage making an attempt to keep away from a crash after he slid in his seat because of the padding. Earlier that 12 months, Jenvey missed savory prize cash on the Nurburgring when a “free alternator wire, mixed with operating with the headlights on, flattened the battery” just some miles away from the end line. So as to add insult to harm, the unique engine blew throughout the take a look at session on the Friday earlier than the Donington Group 5 Worldwide, a non-championship DRM race held at Donington Park.
When the engine was rebuilt, Jenvey was decided to treatment it of its lubrication points. His staff constructed a bespoke sump to maintain the oil in and, with new life breathed into it, the Esprit completed seventh within the Division II DRM race at Zolder, its greatest end in interval. Guarantees of a turbocharged Ford unit got here to nothing after the naturally aspirated mill was ruined when defective con rod bolts failed in observe for the 1981 Silverstone Six Hours. This newest restore invoice was an excessive amount of for the staff, as Jenvey himself admits and the automobile was put into storage.
Quick-forward to 2013 when Leon Douch and Ken Baird discovered in regards to the automobile and started the detective work wanted to find it.
United of their love for the Esprit S1, they “wished one thing that we might race, mainly, one thing a bit completely different.”
The Esprit was thus an ideal match, being eligible for Peter Auto’s Basic Endurance Racing collection that caters in the direction of pre-1980 sports activities vehicles and grand tourers. As luck would have it, Jenvey by no means parted methods with the Esprit and he nonetheless had it – scattered throughout his property that’s – when Douch and Baird, now joined by driver and staff proprietor Greg Caton, phoned him and requested if they might drop by Jenvey Dynamics.
Jenvey, who’d been making an attempt for years to get the automobile again collectively for his son Mike to drive in historic racing, finally struck a take care of the plucky trio and a protracted however fruitful restoration mission kicked off. “It was mainly a naked chassis once we discovered it, a fairly Heath Robinson setup for a number of the structural stuff,” mentioned Leon. “We’ve executed an enormous quantity of labor to get it to the place it’s now, which is why it’s taken so lengthy, to mainly decide all of it aside.” Douch goes on to elucidate that a lot of the aluminum chassis was left untouched however, in any other case, the automobile was strengthened in each space as a result of “I don’t suppose they [back in the ’70s] had the identical form of concentrate on well being and security then as we do now.”
The principle goal was to get the automobile to run reliably, one thing that it by no means fairly mustered again within the day. “It was hellishly unreliable, I feel, primarily as a result of Jenvey made it unreliable,” argues Douch who displays that “[Jenvey] spent a whole lot of time on the engineering facet of issues with out spending sufficient time on making it dependable…”
The automobile was given its shakedown in early March and, since then, it has contested a few Peter Auto occasions with out points. Admittedly, it’s a bit down on energy with simply 240 ponies coming from the two.0-liter unit however Douch claims this will probably be addressed over the winter as Caton’s G-Cat Motorsport staff prepares for subsequent 12 months’s Le Mans Basic. The staff ran this 12 months to hopefully get invited to the occasion that takes place as soon as each two years. “We don’t know for certain [if the Esprit will race at Le Mans]. We’re simply making an attempt to get it dialed-in and get it faster.”
Certainly, this may be the fairytale finish this automobile deserves after its troubled racing profession.
Hailed as a really approachable and quick automobile when all the things was operating easily, the Esprit was by no means fairly in a position to entertain its native fanbase because it ought to have given Lotus’ wealthy heritage in motorsport however a trouble-free run on the 2020 Le Mans Basic would absolutely tidy up the document of this racer that’s been introduced again from the useless 40 years after its aggressive debut.
And what about Bond, it’s possible you’ll be asking.
Nicely, he, for starters, did not drive it an excessive amount of earlier than it dove into the Mediterranean, however, for what it is value, these 210 seconds of nail-biting chase scenes in ‘The Spy Who Beloved Me’ are a number of the greatest within the historical past of the franchise.
For starters, you’ll be able to’t assist however drool on the achingly lovely form of the unique Esprit as Giugiaro designed it, although the chunky taillights got here from Rover’s SD1 and the door handles are straight off the Morris Marina.
It simply appears to be like so good, so glossy, and so purposeful that you simply nearly imagine each Esprit got here with cannons that spray cement, a missile launcher hid by the rear deck, and torpedoes throughout the entrance valance. Sadly, solely Bond’s did. Lotus equipped the crew with a pair of operating and driving Esprits, certainly one of which was modified to behave as a digital camera automobile. A minimum of six Esprit shells, all painted in that very same immaculate tint of white, had been additionally used throughout the capturing of the submersed scenes.
Eager Bond followers already know that the stunt driver initially employed to push the Esprit to its limits throughout its fiery, death-deceiving chase scene proved to be unable to make the automobile slide sufficient. Shifting on to a unique filming location in Sardinia, Lotus engineer Roger Becker enthralled producer Cubby Broccoli by threading the needle up a mountain go earlier than elegantly sliding to a cease in entrance of the on-looking movie crew. Broccoli instantly tasked Becker with all the remaining stunt driving and that’s what he did for the next seven weeks though his preliminary job was to merely ship the 2 vehicles and drive them from one filming location to a different. The one time he wasn’t behind the wheel of the Esprit was throughout the underwater scenes. Then once more, because of the appalling match and end of early Esprits, we guess no one would wish to be inside an Esprit submarine until they’ve a dying want. However that’s a dialogue for an additional day…
