To the only lotus out of the mud and not dye , Wash the ripples but not the demons , TongWai straight in , neither spreading about nor branching out-concise , Fragrant and far-reaching , The pavilions are planted with pure plants , You can look at it from a distance and not play with it .
Quote a famous Neo Confucianism scholar Zhou Dunyi of the Northern Song Dynasty 《 Elaine said 》 To express the author's feelings for the brand lotus , Of course , Don't write the car too politely , Then quote the words of the ancients .

1969 year ,Tony Rudd( Tony . Rudd ) Join lotus , In one year, he was appointed as technical director by golen Zhuowen , At this time, there are two items on his desk , One is the project number M50 Of FR Layout small sports car , To replace old Elan, The other one is M70 project , That is to say Europa My successor , But at that time, most of lotus's human resources were put on the racing car , therefore M70 Even if it does change the direction of modeling design 、 Power system and so on , Even approved by the company's management , But still unable to advance , After all Europa stay 1971 After acquiring a new power system in the autumn of , Not only received new Type 74 Code and continue to improve , And sales continue to rise , Old cars are constantly pushing through the old and bringing forth the new , Naturally, new projects can only be put on hold for the time being . But at the same time 1971 At the Geneva motor show ,M70 Project because of the famous automobile designer Giorgetto Giugiaro( George . Roroya ) With Colin . Zhuo Wen's encounter changed .

Georgiaro The Italian car designer believes that he is no stranger to car fans , He 1955 To join in Fiat Fiat is responsible for the design of special models 、 Later I served Berton broadcom (1959~1965) and Ghia Kiya (1965~1967) Two design bureaus , stay 1967 In, he founded ItalDesign Italian design company , And then a large number of people left “ Origami ” Almost all the models of line style are written by him , BMW, for example M1、 Maserati Bora、DMC DeLorean、 And the first generation of Volkswagen Golf and so on . Lotus M70 At that time, it had been approved , But no one pushed , Goren Zhuowen proposed to let georgiaro out the conceptual design first ,1971 end of the year , The first edition was sent to Lianhua , But it is said that the people of Corinthians are not very satisfied , Because with Maserati's Boomerang The concept car is so much like , With this feedback , Georgiaro offered to get Europa The chassis is studied , But lotus has made it clear to Georgia , The wheelbase and track width of a new car are better than Europa Bigger , And for Georgia lo , It's not a big problem at all ,1972 year 11 At the Turin auto show in June ItalDesign On the platform , One is called Esprit Silver concept car and Maserati Boomerang Concept cars appear together . This design is right for the taste of lotus , Gorian Zhuowen decided to officially start the research and development of new cars , after 18 Months of close cooperation , The first mass production prototype is in 1974 year 12 Month to complete , And this car is named IDGG01.

chart :1971 The first draft at the end of the year , Not recognized by golen Zhuowen , Because it's so similar to Maserati's concept , The style is too Italian .

 

 picture

chart : The second version of the concept car is finally in 1972 It came on stage in , The design is beginning to taste right . The concept car won a lot of praise at the exhibition , Golen Zhuowen decided to cooperate with the Italian design company , advance M70 project .

chart : After the prototype is approved , Lotus immediately organized the R & D team to go to Italy , Work with the georgiaro team to develop , The R & D process is not just about design , It also includes the right Europa Modify the frame of 、 Suspension setting, etc .

chart : The windshield angle of this concept is only 19°, It doesn't meet the requirements of traffic regulations at that time .

chart : The high and middle slot design makes the gear shift extremely easy , I drove several times many years ago, and later S2 and S4, That kind of close control convenience and sexy feeling is really great !

chart :1974 year 12 month , Lotus and the Italian design company produced the first mass production prototype car IDGG01, The angle of the front windshield is restored to legal 24.5°.

chart : Please don't think that the design companies in those years designed a simple appearance , In addition to designing the appearance for customers , Also on the chassis 、 Functional configuration devices 、 Design the production process , Some even act as body manufacturing companies , That is, even the production is contracted .

chart :IDGG01 Cockpit design layout , Almost exactly the same as the mass production version .


 

appearance part 、 Chassis modification 、 The interior configuration and so on have been found , Another work is the research and development of power system, which is also in full swing . Lotus has unparalleled frame and suspension design skills , Everyone on earth knows this ability , But for the power system and transmission system, it is lame , They used to equip their mass production vehicles with their own engine transmissions , Renault and Ford are partners , But as early as 1964 year , Golen Zhuowen has realized the dilemma that this power system is controlled by others , So I hope to develop the new engine through the internal technical team , This work is carried out by the head of power system development Steve Sanville( Steven . Sunville )、 Engineering Director Tony Rudd A team of people is responsible for , This is the lotus 900 Series engine project . This engine is divided into L4 Layout and V8 Two kinds of , The straight four version will use tilt 45° The way to place , But here's an interesting story , That's what lotus used in the research and development process Vauxhall And completed the final design and finalization , Therefore, it is also said that lotus copied the engine of huosu , But in fact, the story is that this TV has won Slant The parameters of the engine in the middle cylinder are just consistent with those designed by the lotus team , So in order to save costs , The lotus team did buy 10 Taiwan back for R & D , But objectively speaking , In fact, each engine in the middle cylinder has the same idea , The real impact on the dynamic performance is the cylinder head , Valve train 、 Valve and combustion chamber, etc , And these are done by Lotus itself . And then , Even a lot of Vauxhall The owner of the car will directly Slant Remove the cylinder head of the engine , Use lotus instead .

The machine New Lotus 900 The engine is 1970 Years to complete , But at this time, lotus itself does not have a suitable new model to use , After all, tilt 45° The installation method of is not that you can install it by looking for a car , Because its mechanical properties are different from those from different angles , therefore , This new engine can only be supplied to other car factories , And they are 1972 In, the first customer was Jensen-Healey, This also makes it the world's first mass-produced multi valve straight four engine .
as for Frame section , After determining the use of their own 907 Engine and from Citroen C35 Behind the gearbox , The front suspension part is designed from Opel Ascona Double rocker arm structure 、 The rear suspension is in the form of semi trailing arm , The braking system is Girling The front and rear solid discs , But the rear brake is the same as many Citroen models , because C35 The transmission is equipped with a braking system , So it also leads to Esprit The rear brake system is also placed on the transmission housing . The rim part is Wolfrace Of 14 " 、 front 6J after 7J, The front wheel 195/60HR14、 The rear wheel 205/60VR14.

chart : It should be said ,Esprit The frame is basically modified from Europa, It also adopts the consistent backbone frame , The vehicle body is of non load bearing type . Its biggest advantage is high mechanical rigidity , Light weight, etc ,Esprit The total weight of is only 900 kg ; But the disadvantages are obvious , That's the lack of protection , Especially for lateral impact , And it's also a non load-bearing body , Comfort is not as good as load-bearing .

chart : The version used in continental Europe has been changed to left-hand drive layout , however , The installation of the engine is tilted to the left , Whether the left and right counterweights are reasonable ?

 

want Distinguish the first generation Esprit It's very simple , The first is its unique front shovel gas dam 、B After the column 1/4 There is no air deflector behind the glass 、 The tail light is similar to Fiat X1/9 style 、Wolfrace Cast aluminum alloy rim is also the first generation Esprit Unique configuration . however , Do not look Esprit It seems that there are many spare parts from other manufacturers , But they account for only half of the cost of the whole car 30% nothing more , in addition 70% All the costs come from self-produced parts , But because the British pound devaluation and the oil crisis had just passed 、 Poor economic environment and other reasons , Give Way Esprit The price is higher than ordinary lotus or old Europa It costs a lot , So from the perspective of a new car, it has been in a disadvantageous situation , Plus lotus's losses , What's more, lotus realized that it can't afford to rely on the local markets in Europe and Britain alone , So they sponsored 007 Movies to open the American market , Of course , stay 1977 Year of 《The spy who loved me》 In the movie ( Iron King Kong bravely broke the undersea city ,1977 year 7 Draw on the moon ),Roger Moore( roger . MOA ) and Barbara Bach( Barbara · Bach ) That section is white Esprit S1 Land can run and play with helicopters 、 If the water can swim and launch torpedo deep-water bombs 、 You can catch a fish out of the water. Humor. The drama of beach tourists has swept the world , It also paved the way for new cars to open up the market in the United States .

however , first generation Esprit The reason why it was replaced so quickly , The big reason is that although in the appearance design 、 In terms of handling performance, it can compete with almost all sports cars of the same age , But its reliability is poor 、 The engine leaks oil due to overheating 、 Insufficient power performance 、 Driveline fault 、 It's not as fast as the legend. It's all a problem , Let the lotus Esprit S1 Criticized by users , therefore , stay 1978 year , After modification Esprit S2 Introduction , To solve these big and small problems that a flagship sports car should not have .
