The Bugatti EB 110 was a mid-engine sports car produced by Bugatti Automobili S.p.A. from 1991 to 1995, when the company went bankrupt. It was the only production model made by Romano Artioli's Italian incarnation of Bugatti.

The Bugatti EB 110 was first shown in Paris on 14 September 1991, the day before the 110th anniversary of Ettore Bugatti's birth for which it was named. The unveiling took place in La Défense under the Grande Arche; the car then paraded alongside the Champs Élysées to Place de la Concorde, escorted by 100 classic Bugattis. A gala evening in the Palace of Versailles concluded the celebration.

The first production car left the factory in December 1991.

In 1992, a lighter and more powerful model with 450 kW (612 PS) at 8250 rpm, the EB 110 SS ("Supersport") was introduced. This car is capable of 216 mph and 0-100 km/h in 3.2 seconds.

Early in 1994 Formula One driver Michael Schumacher purchased a yellow EB 110 SS, giving the company a great deal of publicity. Schumacher retained the car until 2003.

Derek Hill, son of American Formula One champion Phil Hill, was one of three drivers on a team that competed with an EB 110 in the United States at the 1996 24 Hours of Daytona.

Hard times hit the company in 1995 and, as result of chairman Artioli's over-ambitious purchase of Lotus in addition to the company's quest to develop the EB112 four door car, the company was bankrupt. Dauer Racing GmbH of Nuremberg, Germany, bought the semi-finished EB 110 cars in the assembly plant plus the parts inventory through the bankruptcy trustee. The remaining chassis and a version of the engine were later developed by B Engineering into their Edonis sports car.

Specifications
The EB 110 used an entirely purpose-built drivetrain. Engine block, gearbox and final drive housing were incorporated in a single casting—though the lubrication systems were separate—with the gearbox being on the right hand side of the engine. For this reason the engine was shifted 60 mm to the left in respect to the car's centerline.

Engine
The engine was a four overhead cam, 60-valve (three inlet and two exhaust valves per cylinder) 60° V12, with aluminium alloy block and heads and magnesium alloy carters. Bore and stroke measured 81 mm and 56.6 mm, for a displacement of 3499 cc. It was fed via multipoint fuel injection through twelve individual throttle bodies, and fitted with quadruple IHI turbochargers—two in parallel per each cylinder bank—and dual intercoolers. The engine lubrication system was dry sump, inluded an oil radiator, and used a specially formulated Elf lubricant. Engine output was 560 PS at 8,000 rpm and 611 Nm at 3,750 rpm in GT specification; 611 PS at 8,250 rpm and 650 Nm at 4,200 rpm in SS specification.

Acceleration to 100 km/h takes 3.2 seconds, and the GT has a top speed of 213 mph.

Transmission
The manual transmission had six speeds, and used dual-cone ZF synchronizers and a single-plate semi-metallic clutch. The all wheel drive system used three differentials, an front open one, a centre epicyclic gearing with a viscous coupling and a Torsen limited slip differential at the rear; the torque split across the axles was 27% front and 73% rear.

Chassis
The frame was based around a carbon fibre reinforced plastic centre tub built by Aérospatiale. The body panels were fashioned from aluminium, and were bonded or riveted to the frame. Equipped with Gandini's famous lifting scissor doors, it has a glass engine cover that provides a view of the V12 engine along with a speed-sensitive electronic rear wing that can be raised at the flick of a switch.

Suspension was by unequal lenght A-arms front and rear, with coil springs and coaxial dampers, in single pull-rod-operated units at the front, dual at the rear. Brakes were Brembo 322 mm vented and drilled discs on all four corners, with four-piston fixed calipers. Factory-fitted tyres were Michelin Pilot SX MXX3, sized 245/40 ZR18 at the front and 325/30 ZR18 at the rear, on 9J×18" and 12J×18" wheels respectively. The centre-lock alloy wheels were supplied by BBS, and were three-piece forged with magnesium alloy centers on the GT, one-piece 7-spoke cast on the SS.

Performance
Auto, Motor und Sport tested the 412 kW Bugatti EB 110 with the following results:


 * 0–80 km/h: 2.6 s
 * 0–100 km/h: 3.6 s
 * 0–140 km/h: 6.5 s
 * 0–180 km/h: 10.8 s
 * 0–200 km/h: 14.0 s
 * Standing kilometre: 21.3 s
 * Top speed: 336 km/h

Road & Track tested a Bugatti EB 110 with 611 bhp:


 * 0–30 mi/h: 2.2 s
 * 0–40 mi/h: 2.7 s
 * 0–50 mi/h: 3.4 s
 * 0–60 mi/h: 4.4 s
 * 0–70 mi/h: 5.3 s
 * 0–80 mi/h: 6.8 s
 * 0–90 mi/h: 7.8 s
 * 0–100 mi/h: 9.1 s
 * 0–110 mi/h: 10.9 s
 * 0–120 mi/h: 12.6 s
 * Standing $1/4$ mile (402 m): 12.5 s at 119.5 mph
 * Braking 60-0 mph: 112 ft
 * Braking 80-0 mph: 209 ft

The testers suspected that the acceleration numbers could be lowered considerably by using the clutch more recklessly than they did.

B Engineering Edonis
The B Engineering Edonis is based on the Bugatti EB 110 SS but has been extensively re-engineered, retaining little more than the carbon-fiber chassis from the original Bugatti. Both the exterior and interior of the car have been completely redesigned. The 3.5 liter Bugatti engine has had its displacement increased from 3500 cc to 3760 cc. The original four small IHI turbochargers have been replaced by two larger units from the same manufacturer. Engine power has been boosted from 450 kW and 650 Nm of torque to 500 kW at 8000 rpm and 735 Nm.

In addition, the 4WD triple-differential drivetrain from the original Bugatti has been replaced with a much simpler and lighter RWD transaxle, thus saving approximately 70 kg from the total weight. These power figures give the 1500 kg Edonis a power-to-weight ratio of 480 bhp/ton. In addition, the engine's specific power output is an unprecedented 181 bhp/liter. The brand claims a maximum speed of 365 km/h (227 mph), while accelerating from 0 to 100 km/h in 3.9 seconds.

Plans are for B Engineering to build only 21 vehicles from chassis originally built for Bugatti by Aérospatiale (most of the remaining chassis delivered to Bugatti prior to their bankruptcy were delivered to Jochen Dauer when he purchased the assets of the company).

As well as the Edonis, B Engineering also provide spare parts and service for the EB 110.

Dauer EB 110
Dauer Sportwagen in Nuremberg, Germany, bought the remaining stock of EB 110 parts from the Bugatti factory. A complete spare parts catalogue, with exploded diagrams and part numbers is now available from Dauer Sportwagen. The company has used the few remaining incomplete chassis to produce the limited edition Dauer EB 110.

The company Dauer Sportwagen went bankrupt in 2008. All original Bugatti parts especially the high performance parts of the EB 110 SS and the equipment were bought in 2011 by the company Toscana-Motors GmbH (Kaiserslautern, Germany).

Motorsport
The EB 110 participated in the 24 Hours of Le Mans in 1994. The car qualified a very competitive 17th overall and 5th in the GT1 class but did not finish the race. The car is now on display at the Lohéac Automobile Museum.
