The review of cars of the Audi 80
80 (a series of a body 89) class D for the rounded design and «полноватую» the form боковин bodies at us in the country have nicknamed the third generation Audi «бочкой». Configuration with a longitudinal arrangement of the engine has appeared very convenient for versions Quattro (89Q) with the constant full (integrated) drive serving for improvement only of road performance, instead of for passableness increase (a road clearance, as at front-wheel drive vehicles). On "eight-ten" early series established the diversified petrol engines: carburettor (on the early version), with the central and distributed injection, with a turbo-supercharging in working volume from 1,6 to 2,3 l («турбопятерка»), and also economic 1,6-1,9-литровые diesel engines and turbodiesels. Model Audi 90 with other bumpers, equipped mainly рядными «пятерками», only ненамного surpassed "eight-ten" in equipment level. The three-door hatchback of sports type with the truncated wheel base has been named Coupe. It differed the closest back part of salon with very small (295-930) luggage carrier. Its all-wheel drive version Coupe Quattro (a series 89Q) was issued also. As a result of restyling of 1991 (a series of body B4) Audi 80 has received other registration of forward and back parts of a body. The extended cowl has been united with the chromeplated lattice of a radiator, bumpers of other form began to paint in colour of a body. 15-inch wheels became standard. Access to a luggage carrier has been facilitated, and its capacity began possible to increase at the expense of a thrown back back of a back seat. There was a safety pillow. Model Audi 90 has been laid off. Scale of engines have expanded - from especially economic 1,9-litre turbodiesel with direct injection of fuel to 2,8-litre petrol V6. Let out and "the charged" versions of sedan S2 (89-type); S2, S2 Avant and RS2 Avant (В4-type) c forced рядными «турбопятерками» and a suspension bracket of the increased rigidity. Them equipped with bumpers with the increased apertures of air inlets, brakes of type Porsсhe (with bright red supports) and низкопрофильными wheels. In the summer of 1991 has appeared successful four-seater Cabrio which manufacture proceeded very long. This model of one of the cabriolets first in a class (in June, 1995) has received a turbodiesel. For winter operation since 1996 began to offer an easily removable aluminium roof with heating of back glass. Versatile persons Audi 80 Avant have appeared only in June, 1992. Despite not so capacious body, they have appeared popular in a segment of versatile persons for the families which are taking a great interest in sports that was promoted to no small degree by all-wheel drive versions Quattro. Functionality Avant was improved by a back seat put in parts. The solid age (even "the freshest" models have already entered into age notorious «семилеток») does not prevent to remain "flank" one of popular models in the domestic secondary market (at least, in the European territory). Its body thanking оцинковке differs proof anticorrosive protection, but on beaten copies there can be disguised centres of corrosion from inept repair. At excellent ergonomics of a forward part of salon (unless there is no ceiling illumination) on a back seat of all updatings of family to passengers of high growth happens closely, as in domestic "Samaras". Visibility and road performance "flanks" quite correspond to world requirements, but the wheel hydraulic booster is not on all updatings and the luggage carrier volume is a little small. The resource of engines is great (happens much more 300 thousand in km), but directly depends on timeliness of carrying out of servicing and quality of applied materials (oils, filters and so forth) . At many engines big (for the unknown reasons) the oil expense. All-wheel drive versions Quattro it is more difficult in service and repair, but at the expense of it and cost more expensive not usual front-wheel versions. The most simple and reliable there are moderately equipped versions with petrol «четверками» with monoinjection.
