If the expression “sportier” doesn’t exist, then it should be invented to describe the BX Sport, marketed in France from March onwards, in a limited series of 1,600 only for the present.

UNLIKE THE OTHERS
It doesn't look like the other BXs, for many of the component parts of the bodywork tend to give it the image of a “wild” sports car.
These are, among others: a more bulky front with rear streamlining which widens the seating position of the car and seems to flatten it on the ground (like “saloon” racing cars), a cut-up bonnet with a tiny black radiator screen to ensure better engine cooling, “shield” bumpers with front spoiler and recessed fog lamps and rear apron, a side streamlining of the underbody and wing wideners, a wing on the rear flap, a rectangular exhaust outlet, aluminium sport wheels and low cut tyres.
It is available in two varnished metallic colours, either dark or light grey which, when applied to the entire bodywork, blend especially well with the additional parts (bumpers, wings, etc.). The only decoration which features on the model is that of some black components: the window and windshield frames, an outside aerial, chevrons on the bonnet, and the licence plate framing.

BLACK IS BLACK
Black is also the colour of the car’s interior, arranged in a general dark harmony which recalls the interior of the CX GTi turbo, and is close to the anti-reflection ones used for rally cars.
The dashboard and console are metallic charcoal grey. The seats and door panels are fitted with black corduroy with black and grey chevron medallions. The carpet is black, the headliner is grey/dark blue.
The specific arrangement of the various component parts contributes to the sporty style of the model: bucket-shape front seats with headrests (they ensure an excellent driving position with a good side bearing), round dial dashboard of the BX 19 GT with an oil pressure indicator, gearshift lever from the CX GTi turbo, three-spoke sports steering wheel with a special motif in its centre.
On all cars, this very complete equipment includes: tinted window panes, centralized door locking system, electrically-operated front window, rear windscreen wiper, radio pre-equipment, aluminium sports wheels, varnished metallic paint, power assisted steering.

A SPORTS ENGINE
The mechanics have been modified to combine reliability, safety and sporty driving.
The engine comes from the XU 9S engine of the BX 19 GT (aluminium engine, overhead camshaft, 4-cylinder 1,905 cc, bore 83 mm, stroke 88 mm ). It differs, in that it has a specific cylinder head, new inlet valves and timing, special pistons, modified in order to maintain a 9.5 compression ratio, and reinforced piston rods.
The fuel supply comprises a new cast aluminium intake manifold, to allow for two horizontal dual barrel carburettors.
The developement of the engine, and especially the work on the cylinder head, has been done by Danielson’s research department, whose competence is well-known to all car racing fans.
Citroën was responsible for the tuning, the reliability of the mechanics, and brought all the car components to the level of its new performance figures.

HIGH-TORQUE AT All ENGINE SPEEDS
The five-speed gearbox has the gearing of the BX 19 GT. Coupling 16X59. New light alloy wheels and 185/60 X14MXW tyres. The front and rear track have been widened.
All cars are equipped with power steering.
The ground connection, derived from the BX 19 GT is adapted to the car’s great motricity by suspension elements.
The performance figures are not bad : 8.9 seconds to reach the 100 kph mark, 16.4 seconds for the 400 m standing start, 30.5 for the 1,000 m, 195 kph (in comparison with the CX GTi’s 10, 17.1 and 32 seconds, and 185 kph).
The maximum output (126 hp DIN) is obtained from 5,500 rpm, and the range stays constant from 5,500 to 6,000 rpm.
The torque figures are remarkable (17.2 mkg), from the lowest engine speeds (13.5 mkg at 1,500 rpm, and nearly 15 mkg at 2,000 rpm).
Its value is constant between 2,500 and 5,500 rpm (about 16.5 mkg) providing a wide usage range, great driving flexibility and strong engine pick up capacity.
