TARGETS OF DEVELOPMENT

N70ABOOAA

While the ECLIPSE has been finding wide

accep-

tance

as a compact sporty vehicle since its

introduc-

tion early in 1989, Mitsubishi Motors Corporation

has introduced further improvements with major

ac-

cent on the following points to meet the market

needs and make the ECLIPSE a top car in its class.

l Styling

1. Organic and aerodynamic.

2. Wide and low proportions.

l Fun to drive

’

1. Quick acceleration and powerful response

(All models equipped with DOHC engine)

Outstanding straight ahead stability and

lin-

ear steering response

(4-wheel

multi-link

suspension adopted)

3. Outstanding braking performance

Value for money

1. Rich array of features at low price

Low fuel consumption and low repair cost

Technical Features

ENGINE

N70AEOOAA

Two basic DOHC engines are available.

420A Engine

On non-turbocharged models, the

Chrysler-

manufactured 2.0 lit. DOHC 16-valve engine

in-

creases domestic parts content. The engine and

‘L)

transaxle unit, unlike the conventional MMC engine,

is arranged with the engine on the passenger side

and the transaxle on the driver’s side.

4G63 Engine

On turbocharged models, new techniques and

im-

provements have been embodied in the 4G63

en-

N70AEOlAA

gine to provide better performance and lower fuel

consumption.
