Alvis Silver Crest is a 4 or 5 passenger saloon car or coupé using advanced technology intended to provide a top speed in excess of 80 mph and sold at a relatively high purchase price.Announced in mid-August 1937 production ended just before the war when a new-shaped body was beginning production.
Six-cylinders, water-cooled, either 2.4 or 2.8-litres using a four bearing crankshaft and a vibration damper. Camshaft and auxiliaries are driven from the crankshaft by Triplex chain. Synchronised triple S.U. carburettors feed in petrol from twin fuel pumps from a 16-gallon tank at the back of the car.
The 4/5 seater body has two large separate adjustable leather seats at the front and two further seats are provided at the back. The car's instrument panel includes speedometer, clock, gauges showing oil pressure, petrol, thermometer, ignition lamp, ammeter, ignition switch, start control and connection for an inspection lamp.
A new designed chassis with straight box section sidemembers having six tubular cross-members is particularly stiff so the independent front suspension can work properly. Steering is carried out by worm and nut. Automatic chassis lubrication is controlled by the clutch pedal. The car is fitted with a Smith's hydraulic jacking system. The independent front suspension to Alvis's own design is by transverse leaf springs. The semi-elliptic rear springs are underslung. Luvax hydraulic shock absorbers control the springing. A fully floating rear axle is fitted. Wire wheels with bolt-on hubs are supplied fitted with extra low-pressure tyres. Four-wheel, self-energising Girling brakes have large diameter drums which are ribbed for cooling.
When bought as a chassis for a bespoke body the chassis package includes lighting and starting sets, twin electric windscreen wipers, all instrument panel fittings, bonnet, front wings and running boards, battery, twin horns, front bumper, all tyres, foot pump and tool kit.
The motoring correspondent of The Times published his experiences with the smaller engined sports saloon car in August 1937 soon after its announcement. The handsome body he said offers room for five and really comfortable seating. A driver can climb in and out of the car by the near side without too much difficulty. The luggage compartment contained toolboxes which might have been better stowed below at each side of the spare wheel to avoid being obliged to use the door of the boot as a luggage platform. It is delightful to handle, the full-synchromesh gearbox was everything it should be. The steering on the extra-low-pressure tyres was a shade heavy, brakes were powerful. The car's front was always firm and there was no needless pitch and toss.
He also reported that this smaller-engined car was not run in but easily ran up to 70 miles an hour.
