For the third instalment of Iron Man, Tony Stark will still be driving an Audi. This time, it will be an all-electric Audi R8 E-Tron prototype. In the first Iron Man movie in 2008, Stark drove a new R8 while in Iron Man 2, he sat behind the wheel of a R8 Spyder.
There had been rumors that plans to use an Audi R8 E-Tron for the third movie had been scrapped because of concerns related to weight and cost. But this report throws out those speculations. If the R8 E-Tron gets the go signal for it to enter production, it will be equipped with two electric motors that deliver 376 hp and 605 lb-ft of torque. In Iron Man 3, Stark’s girlfriend “Pepper” Potts will also be seen driving the Audi S7.
“Audi is excited to once again showcase the brand’s cutting edge technology and sleek design with the Audi R8 e-tron in Marvel’s Iron Man 3,” said Loren Angelo, General Manager of Brand Marketing for Audi of America. “This is a strategic collaboration for us. Similar to the position of the R8 as an innovation leader, Iron Man’s character consistently evolves throughout the trilogy as he masterminds new trends in technology and engineering.”
Audi revealed that through the R8 e-tron, it is proving that electric mobility can be dynamic and expressive. It has a pair of electric motors whose energy is supplied by the 48.6-kWh battery. With this, the electric motors are able to offer output of 380 hp (280 kW) with peak torque at 605 lb.-ft. (820 Nm). As a result, this allows this high-performance sports car to reach maximum speed of 124 mph (200 km/h) with acceleration from 0 to 62 mph (0 to 100 km/h) possible in 4.2 seconds.
In addition, the battery has an operating range of 134 miles (215 km) on a single charge. The brand revealed as well that in developing the R8 e-tron, it obtained the services of an expert in order to help the electrified production models. Overall weight of the R8 e-tron is 3,924 lbs. (1,780 kg). The body structure itself, and this includes the side sections, weighs in at 439 lbs. (199 kg).
Compared to the R8 Coupé, this is lower by as much as 51 lbs. (23 kg). For those familiar, the R8 Coupé has already set high standards with the Audi Space Frame (ASF) philosophy, which is mainly aluminum based. However, for the R8 e-tron, Audi is utilizing the latest development with regards to the ultra-lightweight construction technology.
Dubbed as Multimaterial Space Frame, it utilizes carbon-fiber-reinforced polymer, or CFRP, on a number of components and serves to complement the aluminum frame. In terms of the bodyshell weight, 75% can be attributed to the metal parts with 23% for the CFRP parts, and the rest for miscellaneous materials. Still, it is clear that the forward structure of this new model uses the classic aluminum design.
But for the occupant cell, majority of the material used is CFRP, with the rear section showing a mix of the two. Further, the CFRP’s supporting trunk insert integrate corrugate crash structures.
What this means is that when compared to a lattice structure made of aluminum, the rear module that is CFRP-based can absorb energy that is five times as large. This material also helps the B-posts, as well as the rear bulkhead, which combine to result in that sandwich concept, and thereby lower the weight by 25 lbs. (11.5 kg).
