Concept Corner: Aero Challenger

Every month we ask the NZV8 cover car over for the concept they’d most like to build, or see built

On the cover of NZV8 Issue No. 121, you’ll have seen the Hemi–powered Cuda that Bic Anderson built, so imagine what ideas would lurk in his mind if reality didn’t matter. 

“OK, since concept is the theme here, I’ve got an idea of what might have happened in 1972,” says Bic Anderson.  

“USAC, a US motorsport governing body, was worried about the fuel crisis, and, as such, decided to create a race series where the Big Three manufacturers (General Motors, Ford, and Chrysler) were tasked with designing high-efficiency cars to race in a state-versus-state race series. Each car would be driven by a professional driver, and would run its state colours and have corporate sponsors. They would be rated on their maximum speed, economy, lap time, and drivability.

“Chrysler decided to use its factory-supported race teams to do its R&D work. Petty Enterprises, Dan Gurney’s company, and Juan Nelson (whose son now runs Nelson Racing Engines) combined to come up with the fastest fuel-efficient race car they could. They chose a ’72 Dodge Challenger as the basis, as it best represented a scaled-down version of its larger B-body cousin — the Superbird. Petty Enterprises transferred all of its wind tunnel info — learned from the low-drag, high-downforce Superbird — over to the Challenger, with proportional nose and rear-wing dimensions.

“Juan Nelson built a twin-turboed 340ci small block using Hilborn’s latest mechanical fuel injection system. The system used a newly developed injector with superior atomization for increased power, economy, and drivability at part throttle.

“Dan Gurney oversaw the build at his premises in California, where, amongst other things, he installed the latest six-speed gearbox from Jerico, along with the latest low run-out wheels from Aero, with the latest Z-rated tyres from Goodyear.

“Obviously, the first car that rolled out of Gurney’s shop was painted in a combination of blues, to represent the Petty and Gurney traditional blue liveries.

“Now that’s an alternative reality I’d like to live in!” says Bic.

Merry Christmas from NZ Classic Car magazine

The Classic Car magazine team is taking a few weeks’ holiday from the work computer and heading to the beach for some kickback time.
Merry Christmas, and have a wonderful summer holiday to all our readers, followers, and fans. Enjoy this special extra time with the family. We will be posting archive articles again in mid to late January.
Have fun, be good and be careful out there.

Two engines instead of one?

Popping two motors into a car is not only complicated, it doesn’t always end well. Donn Anderson recalls early attempts, including John Cooper’s ill-fated original Twini Mini built 58 years ago

For a boost in performance, better traction, and perhaps improved handling to some, two motors seems an obvious solution. It would also eliminate the need to develop a larger engine replacement from scratch, but would that outweigh the not inconsiderable technical difficulties?
The idea of using a pair of engines dates back at least 86 years to the Alfa Romeo Bimotor single seater racing car that was officially timed at 335km/h, or 208mph. Taking a lengthened Alfa P3 chassis, the Italians fitted two supercharged straight eight 2.9-litre and 3.2-litre engines, one in front of the cockpit, and the other behind the cockpit.
