New Morgan Plus Four arrives with BMW power, new chassis

Morgan has launched a completely revised Plus Four, the second of its new generation of BMW-powered models to use the all-new CX bonded aluminium platform pioneered last year in its traditional-looking but all-new Plus Six. 

The car replaces the old, steel chassis 4/4, Plus 4 and Roadster models and is expected to account for around half of Morgan’s annual volume of around 900 cars a year, when customer deliveries begin in late spring. Prices start at £62,995 for the entry-level six-speed manual model, the first time a manual gearbox has been offered in the new chassis. The eight-speed auto version costs £64,500.

Though very similar-looking to the outgoing Plus 4, the new car (which adopts “Four” for its name instead of “4”) is entirely different from its predecessors under the skin; Morgan says only 3% of parts are carried over. The Four’s version of the boned aluminium CX platform is almost identical to that of the Plus Six, apart from necessities such as different engine mountings, but like its predecessors the four-cylinder car itself is a little narrower than Morgan’s most powerful model — in this case by 84mm — by use of shorter front and rear double wishbones, modified wings and slightly smaller wheels and tyres. 

The car still incorporates the usual Morgan high degree of hand manufacture: it has many hand-beaten aluminium panels (though not the wings, which are Superformed) and these are supported by a hand-crafted ash body frame, plus a hand-trimmed leather interior. One notable achievement is the way the the new double wishbone suspension is adapted to low-offset 15-inch wire wheels, a difficult engineering challenge properly regarded by Morgan engineers as a must for the new Plus Four. Silver-painted wires are standard equipment, but elegant alloys are also available.

The new Morgan’s four-cylinder engine, a BMW TwinPower 2.0-litre turbo four (which has a modular relationship to the Plus Six’s in-line 3.0-litre six) produces an impressive 255bhp at 4400rpm, plus 295lb ft of torque between 1000rpm and 4300rpm. The Plus Four weighs a modest 1009kg at the kerb (around 66kg less than its six-cylinder relative) so performance is in the same impressive class as the outgoing V6 Roadster: The auto can run a 0-60mph sprint in just 4.8 seconds (0.4 faster than the manual) with both versions turning a a top speed of 149mph.      

The new Plus Four’s pricing represents a considerable hike over the entry level for the outgoing steel-chassis models (which have been rushed by traditionalists; only about 20 cars are left) but Morgan points out that the new car is 65% more powerful than the outgoing Plus 4, and much more capable on the road, while delivering very similar fuel consumption (around 40mpg combined) and emitting 15% less CO2. Morgan bosses say the low CO2 figures (159g/km auto, 165g/km manual) will greatly assist export sales.
