Toyota has debuted the Sienna R-Tuned concept minivan at the 2015 SEMA Show. This concept was made by Toyota Technical Center in collaboration with DG-Spec performance shop.
The objective was to modify a stock Sienna SE “Swagger Wagon” to deliver radically enhanced performance. Toyota claims that the end result, that is the concept, was able to beat a 6.2-liter V8 Camaro SS producing 426 hp, at the Willow Springs test track by a one-second margin posting a time of 1 minute 27 seconds.
The exterior gets a Kaminari carbon-fiber hood, roof rail delete, 18-inch bright silver Enkei wheels wrapped in Nitto 275/40 tires and a black paint with yellow/white racing stripes going front to back and on the lower flanks. The interior has been fitted with a DG-Spec 4-point roll bar and custom seat mounts, Corbeau Pro Series race seats and G-Force Pro Series 6-point harnesses.
Though the 3.5-liter V6 engine has not been tinkered with, there has been performance upgrades in the form of DG-Spec 3-inch cat-back exhaust and custom cold air intake as well as a super lock LSD (Limited Slip Differential) by OS Giken. The suspension has been changed to DG-Spec double adjustable coilovers at the front and double adjustable body shocks at the rear.
“When we produced the Sienna SE, we started moving in the direction of more sportiness beyond what you would find in a family hauler. With the Sienna R-Tuned, we wanted to see if we could create a vehicle that would push the limits even farther. We definitely proved that it’s possible.” said Andrew Lund, chief engineer for the Sienna at Toyota Technical Center in Ann Arbor, Michigan.
