30/98
There was a demand for more power and in 1913 the engine was enlarged again to 4525 cc. Still using the Prince Henry chassis these cars were called the 30/98 it is believed because the car had an output of 30 bhp (22 kW) at 1000 rpm and 98 bhp (73 kW) at 3000 rpm but an alternate explanation is that it had an RAC horsepower rating of 30 and a cylinder bore of 98 mm.
Externally the cars differed from the Prince Henry by having flat rather than V-shaped radiators.
Only 13 30/98s were made before war intervened with several of these going to Australia where one was used by the importer, Boyd Edkins to break the Sydney to Melbourne and Brisbane to Sydney records.
