RML’s diminutive, Nissan-badged 1.6-liter
turbo powerplant was a perfect fit for the

design completed, EMCO produced the
To bring the Delta Wing to life, a consortium
of motor racing heavyweights was required.
What started out as a free-spirited design
study by Ben Bowlby and his former
employer, Chip Ganassi, grew into a project
encompassing primary partners such as
Duncan Dayton’s Highcroft Racing team,
Dan Gurney’s All American Racers, ALMS
and Elan Technologies founder Don
Panoz, Michelin Tire, Nissan, and more.
Crafting an organizational chart for all
of the responsible parties would take a
bottle of Advil to get through, so here’s
the streamlined version...
With Bowlby and Delta Wing employees
Simon Marshall and Zack Eakin responsible
for the initial IndyCar design and the
revised Le Mans adaptation of the car,
AAR stepped in to construct the prototype
and brought additional design experience
wherever necessary. To simplify the need
for full FIA crash test certification, Bowlby
struck a deal with Aston Martin to use the
tub from its curtailed AMR-One program,
leaving AAR to fabricate the rest of the
chassis and bodywork that bolts to the
homologated LMP1 monocoque.

Island of Misfit Toys. Ben Bowlby’s concept
was initially cast aside by IndyCar, and it’s
only fitting that the engine powering the
car conforms to an idea that was also
written off by the series.
The GRE concept was pioneered by
Audi Sport engine guru Ulrich Baretzky
and lauded for its forward thinking
attributes, but failed to gain traction
among engine manufacturers.
Designed and built by renowned UK
constructor Ray Mallock Limited, the
Global Racing Engine (GRE) was conceived
RML’s 1.6-liter, turbocharged, direct-
injected powerplant conformed to what
Baretzky envisioned, and gave the
company the opportunity to use the unit in
a variety of applications. In the Delta Wing,
the engine is a non-stressed member and
has been designated the Nissan DIG-T.
For Nissan, the Delta Wing project
provides a test bed for exploring the
performance, efficiency and durability of
smaller-capacity engines and will also
provide useful data on improving road car
aerodynamics for greater fuel efficiency.
