Bugatti hypercar uses V16 hybrid
power
Bugatti Rimac has unveiled its next
generation hypercar, Ettore Mate V16T. Under the guidance of new owner
Mate Rimac, the new hypercar adds a quartet of electric motors, but
surprisingly it also features a large-capacity internal combustion
engine as all previous Bugattis did.
"I want to preserve the emotion signature of Bugatti," said Rimac.
"It's the biggest assets of the brand, as these days any Chinese EVs
can run 0-60 in a little more than 1 second."
To that end, Bugatti opts to build an enormous V16 engine, the largest
used in any road cars since the days of Type 41 Royale. It displaces
13.5 liters and employs 4 turbochargers - a tribute to the EB110,
Veyron and Chiron. The block is sourced from Volkswagen group, believed
to be the unsold stocks of Bentley's 6.75-liter V8, and two of them are
bonded together with adhesives and tape to save weight.
To enhance rev and power to meet customer's expectation, Rimac
overhauled its internals. CNC-milled crankshaft, forged alloy pistons
with diamond-like coating, titanium con-rods and valves, carbon-tube
pushrods work together with a pair of new 4-valve heads and
carbon-fiber intake system with individual throttle bodies, enabling a
9000 rpm redline. Output is known to be in the region of 2000
horsepower at around 8000 rpm, accompanied with 1700 pound-foot of
torque. In addition to a quartet of 300 hp electric motors, the new
hypercar will have more than 3000 hp for disposal.
To show off the prominent engine, Bugatti decides to install it at the
front of the car rather than hiding it at the back. Twin-carbon-fiber
bonnet opens to let people viewing its 16 cylinders, with transparent
polycarbonate bonnets listed as option.
The 20kWh battery is installed at the rear axle to help it achieve
50:50 weight distribution. It can be charged at home socket or from
regenerative braking.
"The V16 engine is surprisingly economical to run, too," said Rimac.
"We give it a very sophisticated cylinder deactivation technology,
which can practically turn it from V16 to V14, V12, V10, V8, V6, V4 or
V2, seamlessly and instantaneously."
"What's more amazing is, this gives us different exhaust sound
frequency to play with, actually a full octave," Rimac said excitingly.
"We experimented to use the cylinder deactivation to play the Happy
Birthday song or Amazing Grace. It's truly a musical engine!"
