Siebert-Saunders outlines how the design and development process of ensuring quality and reliability starts long before then: “Each new product takes two years to design and two to develop. The choice of suppliers is key.” A core of 80-100 outside companies supply 100 per cent of the components used in Ariel’s products. There’s the Honda engines, Arch Motors’ tubular steel chassis, Alcon brake calipers, Tilton pedals, Race Technologies dials, Pilkington glass... The big-name list goes on. Siebert-Saunders again: “We like to go to UK suppliers where possible, because the quality is usually among the best, and if replacements are needed, they tend to turn up quickly.”
