0.25 I. - The streamlined shape and rear-engine belong together. The rear-engine dispen-
ses with long driving-organs. An overloading c'.f the back-axle can not take place in as
much as the air-cooled Tatra engines are of light-metal so that their weight in relation to
capacity is almost that of aero-engines. The streamlined Tatra 87 rear-engine is an Eight-
cylinder, air-cooled engine, cylinders arranged in Iwo rows - 4 each in the shape of a ?V"
at an angle of 900. Each row of cylinders is cooled by a blast-engine which ensures the
best working-temperature for the engine at any number of revolutions. The engine is joined
to the gearing and the back-axle, thus forming an unit and is cushioned'on packs of rubber
in the rear of the streamlined car-body. The working of the engine is inaudible inside the
car and its quick starting capacity and marvellous acceleration and climbing capacity are
among its main features serving as proof of its excellent performance. Another special ad-
vantage of the air-cooled Tatra 87 engine is that it may be easily taken out and placed
back in its position. The maintaining of a high speed in the open country, quick accele-
ration in town-traffic and excellent climbing capacity with full load and a sufficient reserve
of energy - are features offered by the air-cooled engine of the streamlined Tatra 87 Car.
The high-barked seats adjustable under way, have been adapted to the natural position
of the human body and so constructed as to make full use of the width of the motorcar-
body, thus providing ample accomodation for 5 passengers. The rear-compartment is
spacious enough to allow stretching of feet which is impossible in any other car of this
size and represents an other contribution towards the comfort of engine-travelling. The
richly upholstered seats offer pleasant repose and with the frontseats folded provide
comfortable sleeping accomodation for 2 passengers. The spacious luggage-compartment
allows taking a greater number of luggage and is dust-proof and easily accessible from
the interior of the car when the backs of the back-seats are folded. To safisty the friends
of coupes, the car has been fitted with a hood which is in perfect keeping with the: stream-
lined shape of the car. When closed, the top is as smooth as that of a limousine and
offers no resistance to the wind; when opened, the flow of air passes over the opening
without causing any draught of air inside the car.
