HRG 1500cc

The HRG was produced at Tolworth in Surrey in small numbers, but many examples achieved success in competition, including the Alpine Rally and the Spa 24 Hour Race. When the original Meadows engine became outdated, HRG turned to a Singer unit in both 1100cc and 1500cc form.   1939 spec bodywork Type open sports Number of doors 2 dimensions & weights Wheelbase 2629 mm 103.5 in   Track front 1219 mm 48 in   rear 1143 mm 45 in   Length 3708 mm 146 in   Width 1500 mm 59.1 in   Height 1321 mm 52 in   Ground clearance 165 mm 6.5 in   Kerb weight 800 kg 1764 lb   Weight distribution (Front) 46.00 % Fuel capacity 45.5 litres 10 UK Gal 12 US Gal aerodynamics Manufacturer Singer Type S-4 SOHC 8 valves total 2 valves per cylinder Main bearings 3 Construction   Bore × stroke 68.00mm × 103.00mm 2.68 in × 4.06 in Bore/Stroke ratio 0.66 Displacement 1496 cc (91.292 cu in) Unitary capacity 374 cc/cylinder Compression ratio 7.00:1 Fuel system 2 SU carbs Aspiration Normal Max. output 61.8 PS (61.0 bhp) (45.5 kW) @4800 rpm Max. torque 96.0 Nm (71 lbft) (9.8 kgm) @4000 rpm Coolant Water Specific output 40.8 bhp/litre 0.67 bhp/cu in Specific torque 64.17 Nm/litre performance Note: A value of -1 means that the car cannot attain that speed. 0-50mph (80 km/h) 12.10s 0-60mph 18.40s 0-100mph -1.00s 0-Quarter-mile 20.40s  Top speed 126 km/h Power-to-weight 76.25 bhp/ton chassis Engine location Front Engine alignment Longitudinal Steering worm Turning circle 9.80 m Suspension Front LA.QE.
