DDR SP4 was conceived in 2001 by Diego Grullon and Juan Ovalle
of the Dominican Republic. The SP4 was designed to be an affordable
kit sports car with supercar looks.
The DDR SP4 team took advice on chassis design and engineering
from experts based in the US, and with their help they created
a custom made tubular steel chassis with aluminium panels covered
by a fiberglass body styled using the legendary Mclaren F1 as inspiration.
The drivetrain of the DDR Motorsport SP4 comes from the Mk2 Toyota MR2 Turbo. Although currently
DDR Motorsport are developing a V8 version of the SP4, the SP8,
which is powered by a GM V8 using a Porsche G50 Transaxle to
deliver the power to the rear wheels.
The DDR Motorsport SP4 features a 6 point roll cage and racing
seats with harness for added safety. Construction of the SP4
and SP8 will take place in the US.
