Boreham Motorworks' New Escort RS

Innovative ‘Ten-K’ engine delivers 335bhp and weighs only 85kg

The newly revived Ford Escort RS will feature a four-cylinder engine that delivers 325bhp and can reach up to 10,000rpm, while weighing only 85kg.

Manufactured by Boreham Motorworks in Coventry and dubbed the Ten-K due to its high rev limit, it resembles the original Escort RS1600’s Cosworth BDA engine but receives significant technological enhancements: the engine crank, rods, subframe, dry sump, and cam cover are crafted from billet steel.  It is considerably larger, with a displacement of 2.1 litres compared to the original 1.6 litres.

The cylinder head draws inspiration from those used in Formula 1 powertrains, designed to optimize the flow of intake and exhaust gases. 

3D-printed castings for the engine block reportedly enable thinner walls compared to a conventional engine, reducing weight.

Additionally, it features individual throttle bodies, producing the distinctive growl reminiscent of the racing Escorts that inspired the new car.

The development of the Ten-K was led by Simon Goodliff and Laine Martin. Goodliff was formerly Ford’s chief engineer, while Martin previously managed Ford engine calibration and control systems.

Under the hood of Boreham’s new Escort RS, there will be a choice between two engines; one is an enlarged and enhanced version of the original Cosworth engine, delivering 182bhp.

The new Escort RS stands out because it is not a restomod but a completely new vehicle, constructed with Ford headquarters' approval.

Only 150 units will be made, with each starting at a price of £295,000.
