Millen needed only 9:46.164 (breaking the 10-minute barrier) to reach the 4300-metre summit of Pikes Peak and claim not only a world record but also the overall event win.
The world record time was made in the very same Hyundai Genesis Coupe that set the record in the Time Attack two-wheel drive class in 2011 with Rhys’ father, Rod Millen, behind the wheel.
The new all-tarmac course (previously it was a combination of dirt and tarmac) meant that Rhys Millen Racing had to make various changes to the car to compensate for the considerably higher average speeds now possible.
The team developed a new aero package for more downforce due to the higher speeds and increased grip levels from the staggered-size Hankook F200 racing slicks wrapped around the lightweight custom wheels from HRE.
A new front splitter with increased strength was fitted along with a redesigned rear wing and wider rear body kit for more downforce and stability, respectively.
On the performance side, the latest Garrett GTX3582 turbocharger was fitted to the Hyundai V6 engine, which develops a staggering 522kW and 949Nm of torque.
The extra power also necessitated more braking power from upgraded brake calipers and additional brake cooling ducts.

In other record-breaking news from Pikes Peak, Toyota Motorsport GmbH smashed the electric vehicle course record in their Radical chassis-based TMG EV P002 racing car with a time of 10:15.380.
Japanese rally champion Fumio Nutahara, who drove the car was also more than 15 seconds quicker than the second place electric-powered competitor Hiroshi Masuoka driving a Mitsubishi i-MiEV Evolution.
The two axial flux motors that power the Toyota TMG EV P002 generates 350kW and 900Nm of torque through a single gear transmission.
The fully electric drivetrain also means that power and torque were unaffected by the thin air over the 19.9-kilometre course, which peaks at 4300 metres.
