General Motors said the car's simulated lap around Mount Panorama would
smash the unofficial lap record set by an Formula 1 car.

Holden celebrated the 50th anniversary of its first win at Australia's Mount
Panorama Circuit in Bathurst with the release of a 1,341-horsepower electric
vehicle concept that it said is capable of obliterating the track's overall
lap record.

Named the Time Attack Concept by Holden, design of the vehicle was split
between Holden's styling and engineering departments. The result is a
low-slung single-seater with extreme aerodynamics and an electric powertrain
to rival that of the Tesla Roadster.

"Automotive design and engineering remains a core strength and competitive
advantage for Holden and for Australia," stated Richard Ferlazzo, Holden's
design director, in the company's press release. "The Time Attack Concept
racer is an illustration of how we can utilize cutting-edge technology to
develop transportation solutions for the future. You can see from the
extremely detailed approach to incorporating the advanced technology in our
Time Attack Concept racer that this is more than just a visual exercise."

Ferlazzo added, "Holden's recent announcement of the expansion of 150 new
engineers to our Advanced Vehicle Development team means we have the talent,
resources and technology to continue delivering to that charter.”


Holden says the TAC uses a quartet of inboard-mounted permanent magnet
electric motors, each generating 250 kilowatts (335 horsepower) and 810
newton-meters (597 pound-feet) of torque. All use stressed-member
three-speed automatic transmissions to connect to individual wheels for
all-wheel drive. Combine them all and you get 1,341 horsepower and 4,393
pound-feet of torque. Including torque multiplication in the 2.97:1 first
gear. You can also get 7,095 pound-feet of torque at launch, which Holden
says is good for zero-to-60 in 1.25 seconds.


Each 18-inch wheel is made from carbon composites, and mounts a 310/70 slick
racing tire. Their grip is boosted by four ground effect-generating venturi
tunnels, a cartoonish diffuser, and fans that suck air from underneath the
car. A hydraulically-controlled rear wing can blend into the bodywork, perk
up to generate downforce, or act as a full air brake to augment the car's
braking. Regenerative braking alone can generate 2.0 gravitational forces of
deceleration, and carbon-carbon disc brakes with active brake ducting
contribute to a maximum braking force of 6 G-forces. Lateral acceleration in
corners can reach as high as 6.5 G-forces.


Powering all this is a graphene battery capable of one megawatt of power
output and 90 Megajoules (25 kilowatt-hours) of storage—relatively small to
keep weight down for the sake of the vehicle's purpose as a time attack race
car. Recharging is achievable in 90 seconds with a one-megawatt charger at
800 volts and 1,250 amperes.


The last time we heard promises of performance this fantastic was at the
Tesla Roadster's surprise debut in November of 2017, where Tesla CEO Elon
Musk laid down performance figures that sounded impossible. According to
Christian von Koenigsegg of the eponymous hypercar manufacturer, the Tesla
Roadster's performance is absolutely possible, meaning that the performance
capabilities of the comparable Holden Time Attack Concept may actually be
more reality than fantasy.

Holden simulated a trip by the TAC around Mount Panorama Circuit, coming
away with an estimated lap time of 1:29.3. For reference, that's 19.58
seconds faster than the circuit's unofficial lap record, set by Jenson
Button in a McLaren Formula 1 car. If you want to see how the Holden TAC
would perform, just set the video of Jenson's lap below to play at 1.25
times normal speed, and turn your volume off.
