Mercedes-Benz, 300SL (Mercedes-Benz 300SL) is the sportscar which German car manufacturer Daimler-Benz (existing Daimler) performed development and production of. I act as a high-quality sportscar of the company, the first model of the SL class.
2 sheeter coupes characterized by a gal wing door and the world's first gasoline direct-injection engine. I was changed to the roadster of the opening after 1957.

Summary
As for "300 of the car name," engine 3 liters cubic centimeter displacement, "SL" mean a lightweight sportscar by abbreviation of German "Sport Leicht". The cord of Daimler-Benz in the company is W198.
In the first place 300SL was developed as a prototypic racing car for the works team (as for the cord in the company W194). In the success that I gained in an international sportscar race of 1952, the victory in Carrera パナメリカーナ Mexico said to be "the world's most severe public road race" gave a strong impression to American sportscar lovers.
There was not the plan that marketed 300SL, but import dealer of New York, max Hoffman (Max Hoffman) expected the demand in the American market and persuaded Daimler-Benz AG with 1,000 firm orders [1]. The announcement of W198 which became "the racing car for public road" was performed by New York international auto show of February, 1954 [2]. In addition, 190SL (R121) which should be called the cheap edition was announced at the same time.
The first coupe model having a gal wing door became the popular car model in spite of large amount of 6,820 dollars. The coupe model became the production end in May, 1957 and shifted to a roadster model afterward. The output is coupe 1,400, roadster 1,858. 190SL released in 4,000 dollars or less gained the success that was commercial than 300SL, and the output reached 25,881. The production of 300SL and 190SL was finished in form to be replaced with 230SL in 1963.
Because many drivers died by an accident, I was given an unfavorable nickname called "Widowmaker" (when I translate it literally "a widow maker").
300SL was a design only for left-hand drive specifications, and the right-hand drive specifications cars were not produced.
In 300SL, it is one of Mercedes-Benz which you should collect for the unique door and the world's first technique most through all generations today. The price reaches to 400,000 dollars. "Sportscar international" ranks 300SL as a sportscar of the fifth place in history.
Characteristic
Gal wing door
Because the door of 300SL became the shape such as the wing of the gull when I left it open in the tip-up with the hinge on the roof, I was called a gal wing door. This method was not designed by a decoration side and came from the blood relationship as the racing car.
The chassis of the 300SL prototype adopted the マルチチューブラー space frame which put a thin steel tube together for the purpose of balancing securing of strength with lightweighting. Because a side member of the top and bottom ran lengthwise through the side of the seat with this structure, the side sill equal to "the threshold" of the door opening has risen. Therefore, for the minimum getting on and off in the race, I will adopt a tip-up door [3]. Alfred noy Bauer of the Director at Mercedes team insisted saying "I write it nowhere that a door limited it to wide difference" and was approved when I received an objection at the time of race participation in a war [4]. An opening did not lay it by the original to the side glass area and I greatly stepped over the side sill and got in and out, but I received advice of the safety from a sponsor and opened an opening when I participated in a race at 24, Le Mans time in 1952 [5].
This method was succeeded to in commercial model 300SL with the same chassis structure. The steering was considered to be the retractability which fell down forward not to hit the knee at the time of the getting on and off. However, there is a fault not to be able to open and close the window in the technique at the time and the heat that the engine emits gets into the room and becomes considerably hot. The rear window had mechanism for the exhaust heat, but did not seem to function very much. The driving in midsummer was full of severe を in those days because it was the time when there were few thoughts to put a car air-conditioner on a privately-owned car.
It was a sportscar given priority to performance and was not the design that regarded getting on and off characteristics and comfort as important, but the riding of this car fell and expanded, and, for the well off who escorted the woman dressed in a skirt and the dress, as for the hate, it was the slightest problem. A frame was designed in consideration of daily use in the later roadster models again and a shape, the opening and shutting direction of the door became common and became able to open and close the window. Still, from the narrowness of the opening because of the steel tube space frame, I needed some custom for getting on and off.
Fuel direct-injection engine
As for the 300SL prototype, a race tuned up a 3.0L series six cylinders SOHC engine of 300 limousine (W186) in 171 PS from 115 PS and I could incline to the left 50 degrees and set it up. They adopted a bosh mechanical fuel injection device made replacing with a carburetor made in ソレックス in marketing type 300SL, and, as for the best output, original a little less than 2 times 215 PS / 5,800 rpm[6] (by the SAE indication 240 PS [7]), the greatest torque produced 28.0kgm / 4600 rpm [6].
This new fuel direct fuel injection equipment which was a beginning brought a maximum of 260km/h per an hour in a gasoline-powered car. 300SL was the fastest car for a stock car in those days. As for the maintenance, the technique that was higher than a current electronic fuel injection device was required. It continued jetting gasoline until an engine stopped even if the mechanical fuel pump stopped the ignition. This gasoline washed away the oil of the wall surface of the cylinder without burning and was detrimental. Besides, because the effect in the race was equipped with a large oil cooler of remarkable 10L than town riding, speed that an evaporation effect of the residual gasoline decreased and washed away oil quickened and oil exchange was necessary every approximately 1,600km and shortened more in an exchange period. The clutch is very heavy, and many drivers are supposed when a calf ached on the next day. A spring was attached to reduce power to pedal it by roadster of the latter period.
Variation
300SL prototype (W194)
The works machine for the sportscar race. Newly-designed, but the chassis and the body misappropriated the engine and the availability of traffic facilities for shortening from 300 limousine (W186) during a development period. "SL" means "Super Leicht" (super light weight) at the plan announcement stage [8] and holds down weight to 870 kg by space frame and a body made of lightweight aluminum. The oval that the line of the body is round than a marketing type, and the front grill is flat.
The deployment of the supercharger-type engine and pneumatic brake was tested parallel to three races. In 1953 after the race activity, the test car of transaxle and the fuel injection engine is produced, too.
300SL coupe / roadster (W198)
A road version to be equipped with a gasoline direct-injection engine. It became the steel body except bonnet and door, トランクリッド, and the vehicle weight largely increased. The front was performed a facelift of, and the line of the body became the design with the intonation, and the fin on the wheel house and an air vent for the exhaust heat were added. The interior decoration was changed to the in total high-quality specifications in the constituency, too. It was optional to a roadster, and a putting on and taking off-type hard top roof was prepared for.
I might cause sudden understeering and lowered the pivot position of the swing axle in the roadster model, and the rear suspension was improved by the change of the camber to show mild behavior. In addition, a fuel tank was downsized by roadster, and a trunk room was extended. The wheelbase does not change, but the full length becomes slightly long.
The design of the front rotation is different from a coupe model in a roadster model, and the roadster is a heteromorphic vertical oval 2 light type head lamp whereas a coupe is a round shape 2 light type head lamp. But, depending on the hope of the customer, there is not a little the example that the Daimler-Benz head office changed round shape and vertical head lamps [9]. The individual known as a favorite car of Yujiro Ishihara in Japan is a coupe with the head lamp of the roadster type.
In addition, a few 300SLS of the open sports model exist, too.
190SL (R121)
The appearance is 300SL and a common silhouette, but the contents are another thing and put M121 engine (110 PS) of the carburetor-style 1.9L inline four-cylinder SOHC on a chassis of W121 origin. It was released as a roadster, and a hard top model was added later.
As for the brakes, all front and back of them were drum brakes at first together 300SL, 190SL, but are switched to a disc brake after 1961.
Race career
Mercedes-Benz which stopped race activity after World War II plans return to Grand Prix race. I produced 300SL prototype as the preliminary stage and made works participation in a war for a sportscar race only in 1952. The engine output had only 175PS, but even a high-speed race showed surprising ability against Ferrari, the powerful enemy such as the jaguar at light weight by a chassis with a little air resistance. Superior reliability of the mechanism and the support system of the impregnable guard became the factor of the success, too.
I get the second place and the fourth place in ミッレミリア of the debut race. I got the first victory in an opening act race of the Bern GP, but master hand Rudolf カラツィオラ gets injured and will withdraw from the front line. Because Pierre ルヴェー (talbot) of the first place retired one hour before a goal, Hellman Lang / Fritz lease group carried out overall victory in the race at 24, Le Mans time of 1952. After the victory in the race of the 25th anniversary of local ニュルブルクリンク, I made an expedition to Carrera パナメリカーナ Mexico performed in Mexico and curl クリンク / Hans クレンク group won the championship and completed works activity.
A famous episode of Carrera パナメリカーナ Mexico includes the vulture collision that attacked the Class クリンク / クレンク of the champion. While I run a gap in 200km /h, one of them of a flock of vultures which flew away collides in a windscreen from the roadside. クレンク of the navigator performed bloodshed by the shock and lost consciousness at one time, but has finished running to the 70km former tire service point without stopping a race. I attach eight iron fences before a windscreen as measures and will run afterwards.
The works activity with the vehicle based on marketing type 300SL was not performed, but enlivened the race scene by activity of プライベーター including GT class championship of ミッレミリア.
In 1955, Mercedes conquers a world sportscar championship by 300SLR (3 liters straight eight fuel direct-injection engine). But, unlike 300SL where W194 is a base although I am similar, F1 machine W196 which is a racing car designed next to W194 is a base, and, in 300SLR, as for the name, there is not the direct connection in 300SL and 300SLR.
Reproduction
In 1996, two customized cars which I poured a body of 300SL over on the engine made in AMG and the latest chassis were produced by a hand of Mercedes, and an outside magazine scooped all the others with this existence (car graphic delivers it in Japan). I report whether an orderer is light らかされなかったが, King Bruneian Hasa null Bolkiah. In original 300SL, only left-hand drive specifications were made, but these two were right-hand drive specifications.
In 2009, gal wing United States Corporation announced the replica model production of 300SL [10]. This made the prototype that participated in Carrera パナメリカーナ Mexico a motif not a marketing type.
SLS AMG which was used as a safety car of the F1 succeeds to a design of 300SL including the gal wing door.
After accusing a company of Germany which Daimler prepared a replica of 300SL without permission in 2012 and sold, and having won the case, I showed a design to scrap the replica and showed a posture to refuse an illegal copy [11].
