Based on a 1988 Chevrolet Corvette, the famous Callaway Sledgehammer was built by Callaway to exceed all existing top speed records and as a showcase for Callaway’s industry-leading engineering expertise. For years the Sledgehammer owned the record as the fastest street-driven car in the world, having set the mark on October 26, 1988 when John Lingenfelter drove it to an incredible 254.76 MPH at the Transportation Research Center (TRC) in Ohio, an enormous facility with a 7.5 mile oval track. The record run occurred after the Sledgehammer was driven from Callaway headquarters in Old Lyme, Connecticut to TRC.

Rated at 898 HP and 772 lb-ft of torque, the balanced and blueprinted engine was hand built by Callaway Cars using a 4-bolt main NASCAR-spec GM "Bowtie" engine block, Mahle pistons on forged connecting rods, a special cam to enable both a docile drive around town and voluminous breathing at high engine speeds and Brodix aluminum heads for maximum power and durability. Extensive research was required to efficiently package the engine within the Corvette’s tight confines, which also were made to accept twin Turbonetics TO4B turbochargers, matching intercoolers and all the plumbing necessary to make it all work.

Carroll Smith tuned the Sledgehammer’s suspension for high speed stability by relocating the lower control arms, reducing the car’s ride height by one inch. Koni shock absorbers were used in conjunction with 17-inch Dymag aluminum wheels wearing specially made Goodyear tires developed for the high speed run.

Inside the Paul Deutschman-designed Callaway Aerobody is a mostly stock interior modified for the high speed run with a leather padded roll bar, 5-point harnesses and instruments for monitoring goings-on beneath the hood. And yes: it still has the factory air conditioning and sound systems!

In 2013 the Sledgehammer was inducted into the Bloomington Gold Great Hall, which “recognizes 50 people and 50 Corvettes that significantly influenced the Corvette Phenomenon” – a great honor for one of the world’s great Corvettes.

1991 Callaway Series II Super Speedster
Price: $ 375,000
Candy Wine / Ivory
Callaway Series II Super Speedster 1 of 2
Only Speedster with LM body work
1 of 3 Callaway Twin Turbo LT5 engines
Built using a 1991 ZR1
Candy Wine Red paint with Ivory interior
This twin turbo LT5 delivers over 766 HP making it the most powerful of all speedsters
Unique Callaway double-bubble removable hardtop
3,636 actual miles
This 1991 Chevrolet Corvette Callaway Super Speedster LM is the second of only two so-called Series II Super Speedsters based on the ZR1 model. The offspring of collaboration between Corvette performance guru Reeves Callaway and designer Paul Deutschman, the Super Speedster LM is an astonishing step up on the original Speedster, taking full advantage of the ZR1’s Lotus-engineered, all-aluminum DOHC engine and 6-speed manual transmission. One of only three twin turbocharged and intercooled LT5 engines built by Callaway, it delivers a pavement-shredding 766 HP, making the car the most powerful of all the twelve Speedsters produced by the company. More than “just” an incredibly well-engineered engine swap, the Callaway possesses engineering modifications to the suspension and driveline that fully complement its massive power output. The Le Mans body is the only one used on a Speedster. Designed by Paul Deutschman, the Super Speedster LM is a unique combination of his brilliant Callaway Speedster and the dramatic and aerodynamically efficient Le Mans GT2 pole-winning Callaway LM racer. Luxurious appointments abound in the LM’s interior, which features the consummate craftsmanship of Johann Merkhofer. Lavishly finished in leather and suede with specially embroidered seats, it is fully equipped with comfort and convenience features that include air conditioning and Delco Bose stereo with CD. Unique among Callaway Speedsters is the car’s removable double-bubble hard top, which shares the car’s gorgeous Candy Wine Red paint and evokes the closed-cockpit C7R racers.

1990 Callaway Series II Super Speedster
Price: $ 300,000
Cherry Smash Red / My Favorite Blue
1 of 12 Speedsters produced
1 of 3 Callaway Twin Turbo LT5 engines
Built using a 1990 ZR1
The first of only two (2) series II Super Speedsters
Cherry Smash paint with My Favorite Blue interior make this a truly unique vehicle and the only one without LM body work
13,174 actual miles
This 1990 Chevrolet Corvette Callaway Super Speedster is the first of only two Series II Super Speedsters built by Callaway. It also stands apart from the ten twin-turbo small block equipped Callaway Speedsters by virtue of its LT5 engine. Building on the ZR1’s Lotus designed DOHC 32-valve V-8, Callaway added twin turbochargers and intercoolers, necessitating the development of a new engine management system and higher flow fuel injection and exhaust systems, including tube headers and new catalytic converters. The 750 hp engine itself is blueprinted and magnafluxed and fitted with a forged crank and Cosworth pistons. Accommodating all the extra plumbing required by the twin turbos was a complicated affair, solved in large part by redesigning the front frame and crossmember. In addition, the unique carbon fiber front bodywork features air inlets and outlets for the twin intercoolers. The Super Speedster’s proven competition suspension incorporates fully adjustable coilover shock absorbers to enable fine adjustments to ride height and weight distribution. Callaway-specified Brembo disc brakes stand in for the stock Corvette units, working through massive Bridgestone tires on O.Z. Racing wheels. It’s not just awesome performance that characterizes the Callaway Super Speedster. A true roadster, the Super Speedster keeps a low profile with cut-down windshield and side glass and smoothly arcing headrests integrated into the rear glass. In contrast, there is nothing “low profile” about the Super Speedster’s stunning Cherry Smash paint and My Favorite Blue leather interior. This is truly Callaway flair at its rarest and best.

1991 Callaway B2K Twin Turbo Convertible
Price: $ 125,000
Periwinkle / Gray
The Mini Sledge 1 of 12 Callaway Twin Turbo Corvettes were built with the 500 package
Callaway Twin Turbo #501
One of only a handful of Series 500 RPO B2K Callaway Corvettes
Unique Periwinkle Purple paint
Offered from the original owner's collection
10,226 actual miles
Original purchase agreement and financing contract
After four years in the Corvette catalog as Regular Production Option B2K, Callaway Twin Turbo conversions ended after the 1991 model year. Callaway completed the 500th Twin Turbo conversion on September 26, 1991 and subsequently built another 12 cars with special badging and options; these were the Callaway 500 Series cars, also known as Speedsters for their special open body design by Paul Deutschman. The Callaway was still the most powerful Corvette available, cranking a healthy 400 HP and 580 lb-ft of torque, well ahead of the ZR1’s output of 375 HP and 370 lb-ft. Known as the "Mini Sledge" because of its similarity in engine modifications to the famous Callaway Sledgehammer, this 1991 Callaway Series 500 Twin Turbo is number 501, the first of the 500 Series cars and the only one finished in its unique Periwinkle Purple paint. Like the other Series 500 Twin Turbos it wears the unique Speedster body and O.Z. 3-piece racing wheels, special 500 Series badges on the dash and under the hood on the driver’s side intercooler.

Callaway C7R Racecar
Price: $ Inquire
Silver / Carbon
1 of 2 Callaway C7Rs built in 1997
The other belongs to founder Reeves Callaway
The first completely all Callaway automobile
Full monocoque carbon fiber front end
Mid-engine powered 383 all aluminum engine with 640 HP
Rear trans-axle
Driven by Ron Fellows, Johnny Unser, Boris Said and Enrico Bertiggia
Spare graphics included
Sold on Bill of Sale
In 1997 Reeves Callaway unveiled this Callaway C7R GT1, a full monocoque racing machine employing front mid-engine/rear transaxle design and powered by a Corvette-based 383 CI all aluminum V-8 developing 640 HP. The first of only two built – the other remains in Reeves Callaway’s personal collection – it is the first car built completely by Callaway, its purpose being to showcase his company’s capabilities as a constructor of high performance automobiles. Designed by Paul Deutschman to be the most powerful, lightest weight sports GT commercially available, the C7R GT1 has a power-to-weight ratio of 3.6 pounds per horsepower, exceeding such extraordinary cars as the McLaren F1 (4.0/HP) and the Ferrari F40 (6.0/HP). Its aerodynamic design slices through the air while simultaneously generating high speed downforce that exceeds the weight of the car, resulting in superb handling and stability. This Callaway C7R GT1 was driven in the 1997 Rolex 24 Hours of Daytona, where it led its class. Its handling and aerodynamic performance left an enormous impression on drivers Ron Fellows, Johnny Unser, Boris Said and Enrico Bertaggia. In keeping with the C7R’s mission of winning endurance races, the car is remarkably simple and efficient in design to ensure maximum reliability and simplify maintenance and servicing. The Callaway C7R GT1 was designed as a competition car adaptable to preparation as a road car. Rules changes forced the two C7R GT1 cars from competition later in 1997, but both cars proved the design’s enormous potential and remain a testament to the Callaway organization’s accomplishments as a manufacturer of super high performance automobiles.

It sold to a Callaway collector who enjoys it very much. And the white 88 convertible from Automobile Magazine (article: Sundae Drive) sold, as well. So did the Corvette Boat.
