V 80. letech se v\u00fdrobci supersport\u016f p\u0159edh\u00e1n\u011bli v tom, kter\u00fd z nov\u011b uveden\u00fdch model\u016f dos\u00e1hne vy\u0161\u0161\u00ed maxim\u00e1ln\u00ed rychlosti. Co naplat, \u017ee to byla v podstat\u011b jen teorie. V\u017edy\u0165 i maxim\u00e1ln\u00ed rychlost t\u0159eba 280 km\/h je natolik velk\u00e1, \u017ee vyzkou\u0161et ji v b\u011b\u017en\u00e9m provozu lze leg\u00e1ln\u011b pouze na n\u011bkter\u00fdch \u00fasec\u00edch v N\u011bmecku.<\/p>\n

Ve skute\u010dnosti ale ne\u0161lo o to, aby majitel takovou rychlost\u00ed jezdil. Smyslem byla presti\u017e. Porsche 959 jelo u\u017e v polovin\u011b 80. let rychlost\u00ed 317 km\/h. Velmi z\u00e1hy jej v\u0161ak p\u0159ekonalo Ferrari F40 s nejvy\u0161\u0161\u00ed rychlost\u00ed 324 km\/h. Devades\u00e1t\u00e1 l\u00e9ta p\u0159inesla maxim\u00e1lku kolem 350 km\/h (Jaguar XJ220 a Bugatti EB 110) a\u017e 375 km\/h (britsk\u00fd McLaren F1), kter\u00fd p\u0159ekonalo a\u017e zm\u00edn\u011bn\u00e9 Bugatti Veyron. Ferrari F50 jelo trochu p\u0159ekvapiv\u011b \u201ejen\u201c 325 km\/h, tedy o kilometr za hodinu rychleji ne\u017e p\u0159edchoz\u00ed F40.<\/p>\n

To se ale st\u00e1le bav\u00edme o Evrop\u011b. Sportovn\u00ed vozy se v\u0161ak sna\u017eili vyr\u00e1b\u011bt tak\u00e9 Ameri\u010dan\u00e9.

A tedy notn\u011b zastaral\u00fd. Z\u00e1sadn\u00ed zm\u011bna p\u0159i\u0161la v roce 1984 se zcela novou corvette. Z americk\u00e9 legendy se r\u00e1zem stal v\u016fz, kter\u00fd svou sofistikovanost\u00ed p\u0159ipom\u00ednal nejlep\u0161\u00ed evropsk\u00e1 sportovn\u00ed auta zna\u010dek Porsche a Ferrari.

Dne 26. \u0159\u00edjna 1988 dos\u00e1hl Sledgehammer Corvette v Dopravn\u00edm v\u00fdzkumn\u00e9m centru v East Liberty v Ohiu ov\u011b\u0159en\u00e9 maxim\u00e1ln\u00ed rychlosti 406,4 km\/h!

Sledgehammer mo\u017en\u00e1 p\u0159inesl j\u00edzdn\u00ed v\u00fdkony dragster\u016f na ve\u0159ejn\u00e9 silnice, av\u0161ak st\u00e1le se jednalo o Corvette C4.

Sledgehammer Corvette tak bylo auto dvou tv\u00e1\u0159\u00ed. Nekompromisn\u00ed supersport, kter\u00fd jste mohli vz\u00edt i na z\u00e1vodn\u00ed dr\u00e1hu, z\u00e1rove\u0148 ale auto, s n\u00edm\u017e mohla va\u0161e man\u017eelka jezdit pro potraviny do supermarketu.<\/p>\n

Motor dostal dv\u011b velk\u00e1 turbodmychadla Turbonetics T04B. I d\u00edky nim se motor mohl pochlubit nejvy\u0161\u0161\u00edm v\u00fdkonem 898 kon\u00ed (660 kW) a maxim\u00e1ln\u00edm to\u010div\u00fdm momentem 1046,69 N.m. Bylo to v dob\u011b, kdy tov\u00e1rn\u00ed corvette nab\u00edzela maxim\u00e1ln\u00ed v\u00fdkon motoru 240 kon\u00ed (176 kW). Rekordn\u00ed Sledgehammer byl vybaven p\u0159evodovkou firmy Doug Nash, s\u00e9riov\u00e1 auta ale m\u011bla manu\u00e1ln\u00ed \u0161estistup\u0148ov\u00e9 \u00fastroj\u00ed od ZF.<\/p>\n

Pneumatiky za milion<\/p>\n

Velmi zaj\u00edmav\u00e9 to bylo s pneumatikami. Za t\u00edmto \u00fa\u010delem oslovil Callaway firmu Goodyear s \u017e\u00e1dost\u00ed o pneumatiky, kter\u00e9 by vypadaly jako standardn\u00ed Goodyear Eagles, ale z\u00e1rove\u0148 by byly schopn\u00e9 auto bezpe\u010dn\u011b v\u00e9st a\u017e do rychlosti 480 km\/h. Americk\u00fd v\u00fdrobce pneumatik souhlasil. V\u00fdvoj t\u011bchto speci\u00e1ln\u00edch pneumatik jej v\u0161ak vy\u0161el \u00fadajn\u011b na milion dolar\u016f. V roce 1988 \u0161lo o ekvivalent dne\u0161n\u00ed \u010d\u00e1stky 2,76 milionu dolar\u016f. Pneumatiky byly vyvinuty pro rekordn\u00ed j\u00edzdu Sledgehammeru. Po jejich \u00fasp\u011b\u0161n\u00e9m absolvov\u00e1n\u00ed si speci\u00e1ln\u00ed a z\u00e1rove\u0148 velmi drah\u00e9 vzal zp\u011bt.<\/p>\n

To ale tak\u00e9 znamen\u00e1, \u017ee nebyly kompatibiln\u00ed s proklamovanou nejvy\u0161\u0161\u00ed rychlost\u00ed vozu. Jinak \u0159e\u010deno, uvedenou nejvy\u0161\u0161\u00ed rychlost p\u0159es 400 km\/h tak byl ve skute\u010dnosti schopn\u00fd dos\u00e1hnout pouze rekordn\u00ed v\u016fz.<\/p>\n
