Rover 2300 series 1


The 2300 (and 2600) were launced in Ocotber 1977. But actually available in the showrooms until the folling May. The earliest production examples of bot cars therefore had the "S" suffix registrations. They had the same bodyshell as the 3500 but there were several differences in their running gear, specification levles and appearance. Both cars used the new designed six cilinder engines only difference between them were the crankshaft and the pistons. The engine had a cast-iron block and aluminium allo cylinder head. A belt driven overhead camshaft and twin SU HS6 carburettors. In short-stroke 2300 form it offered 123 Bhp at 5000 rpm and 134 lbs/ft of torque at 4000 rpm.


Both the new models share the same body style as the 3500, which attracted high praise both in the preliminary car clinic and subsequently from the Press and the public at large. In keeping with a model range in this class, exterior trim differentials are restrained. In order to make the feature differences between the two models easy and quick for you to refer to we have provided the features of the 2300, which differentiate it from the 2600.

Sharing the same body shell, the 2300 possesses all the styling advantages of the 3500. The sleek smooth profile gives straight-line stability, minimal wind resistance, and enhances performance and economy; while the five-door configuration combines prestige with practicality.
The monocoque construction gives high torsional rigidity and also has the advantage of lightness to contribute to a good power-to-weight ratio.


Interior Trim

The 2300 maintains the Rover tradition of high levels of comfort and interior luxury, with a fully carpeted passenger area, reclining front seats, and standard head restraints. The sewn-pleated cropped nylon seat facings are highly efficient in providing comfort in extremes of heat or cold and lends itself to easy cleaning.

Features such as the rear seat centre armrest, brushed nylon roof lining. and recessed padded sunvisors (complete with front passenger's vanity mirror and driver's ticket pocket) which pivot to the side windows, all build up the feeling of comfort and luxury associated with the marque. A one-piece cut-pile carpet covers the seating area while the boot area is rubber trimmed; the theme of practicality with prestige designed to appeal to fleet users is continued with durable PVC-covered armrests. On all 2300s the fascia, 'A' post finisher, leather-covered steering wheel, centre console, mar parcel shelf and ashtray are in Caviar trim.

The 2300 also features the new seat belt mountings introduced with the 3500, which incorporate the lower fixing point on the seat frame. This safety feature ensures that the belt remains in the some position across the hips of the occupant whatever the seat position. As with the 3500, the steering column is adjustable for rake and reach.



A major advantage of the 3500 is the comprehensive range of interior equipment, which makes its competition look positively spartan by comparison. At its relative market position the 2300 offers a similar wealth of interior luxuries, including a push-button twin-speaker radio (with optional tape player), clock, cigar lighter, twin locking gloveboxes, and internally adjustable driver's door minor. In addition, the range of controls and instrumentation is both ophisticated and extensive; a full list of other interior equipment is detailed below

Roominess with flexitbility

In requiring a smaller engine the 2300 buyer could still obtain all the roominess and carrying capacity of its larger brothers. The wide track and body of the new Rover enables it to carry three adults comfortably in the rear, experiencing the extra ride comfort afforded by the long wheelbase, while the estate car facility of the tailgate and fold-down rear seats provides a clear 35,4 cubic inch feet of luggage space.


Heating and Ventilation

The Rover 2300 incorporates the new side-window demister system first introduced with the 3500 as well as a standard heated rear screen, 3 speed heater/blower and rear compartment heating for extra passenger comfort.

In effect, the level and sophistication of the new 2300's specification sets new standards in its class, and represents outstanding value for money. The new standards are now less evident in the performance achievements recorded.


Performance and Economy

You are now aware of the refinements which add to the 6-cylinder's advantages in terms of per-formance and economy. We can now gain a more precise idea of ways in which economy relates to performance by looking at the graph below which shows the power curve of the 2300 in relation to fuel consumption.

You can see that the engine achieves maximum torque of 134 lb ft at 4000 rpm, in a slow curve giving good tractability over all engine speeds. If you look at the fuel consumption line you can see that it remains steady right into the higher rev ranges, only rising significantly at over 5000 revs.

Optimum economy — visible in the dip of the fuel consumption curve—is obtained at around 1500 revs and 3500 revs; the approximate road speeds in top gear, at these revs, are 30 mph and 70 mph. In other words the engine is designed to maintain competitive fuel economy during high-speed cruising and town driving alike.

Much of the success of this combination of high performance with economy is due to the features you already know about:

• Special valve operation permitting cross-flow design and optimum valve angles.

• Efficient carburation giving a lean mixture for economy yet providing maximum performance.

• Twin exhaust outlets for unimpeded clearance of exhaust gases. • Aluminium cylinder head and camshaft carrier for lightness and good heat con-duction.

Fuel economy tests are obviously tentative at this early stage, but indicate that the 2300 with its 4-speed gearbox is likely to return a competitive steady 50 mph figure of 34.0 mpg.
