Infiniti Q80 Inspiration concept hybrid delivers 550 hp with 42.8 mpg fuel economy

Infiniti unveiled the Q80 Inspiration concept car at the 2014 Paris Motor Show, it what it called a signal of its intent to break into the top tier of the premium sedan category; the concept will lead to a future model. The four-door fastback is powered by a hybrid electric powertrain that is expected to deliver 550 hp (410 kW) with fuel consumption of 5.5 L/100 km (42.8 mpg US) and CO2 emissions of about 129 g/km.

The powertrain incorporates a new aluminum-based downsized twin-turbocharged 3.0-liter V6 that is part of a new engine family which will be introduced within the next two years. (Infiniti plans to double its powertrain range over the next five years.) The 450 hp (336 kW) V6 gasoline engine will be supported by an electric motor powered by a Li-ion battery pack, capable of adding around 75 kW (100 hp) hybrid power boost when required, and a 9-speed automatic gearbox.

Combined engine and motor system torque is 750 N·m (553 lb-ft). Acceleration from 0-60 mph takes less than 4 seconds, and the top speed is limited to 155 mph (250 km/h).

Driving the 22-inch rear wheels under normal conditions, the vehicle’s torque can also be split by up to 50% between the front and rear axles to maintain composure in moments of limited grip. Drivers can manually opt to stay in all-wheel drive too.

Infiniti’s Q80 Inspiration also previews the company’s philosophy on autonomous technology—i.e., that it should enhance the driver and not restrict him or her. This driver-centric approach, integral to Infiniti’s vision for the premium sector, is exemplified in on-demand systems.

Using cameras, lasers and sensors, the technology can be employed by the driver when needed through a button on the left-hand side of the steering wheel.

Ongoing dialogue between the driver and the autonomous driving technology system, via an HUD display projected on the windshield, enables the driver to utilize the driving assistance at his/her own discretion.

The system emits tones suggesting a course of action for the driver in heavy traffic or in highway mode. The final decision—whether to accelerate and overtake or whether to brake and fall in behind the car ahead—always rests with the driver.

With the HUD, the driver is in command of what is projected onto the windscreen via an Infiniti InTouch-style touchpad in the center console.

The company also introduced the the new 2015 Infiniti Q70 to Europe during the show. Powered by a new 2.2-liter, four-cylinder turbo diesel engine, it delivers 170 hp (127 kW) of power and 400 N·m (295 lb-ft) of torque.

The Hummer of hybrids.

Or does Tesla win that title; this is, after all, only a concept.

Good point, TT.
However, since renewable electricity is non-polluting and cheap, there will be much less pressure for conservation.

Good fuel economy and you still have the possibility to 'use' 550 h.p. The drawback is that it cost a lot and the peoples that will buy it will crush the gas pedal exceeding the 42 mpg rating by a wide margin because it is rated at low speed and slow acceleratioons. Also it will cost a lot in maintenance if something break and you will have the disanvantage of only repairing at the costly far away dealer instead of in every mechanical shop. All in all I prefer my dodge neon for trabelling except to tow a heavy trailer.also my dodge neon is more confortable and we sit more confortably and have a better view outside.

I won't buy that car at that price because it don't fly and it don't have ejectable seats in case of accidents.

Yes, and even if much of the electricity is not renewable, and therefore is somewhat polluting it is cheap (partly because of no road taxes).

So, in fairness, it might only be the Hummer of hybrids.

But it might be the Prius of luxury vehicles, a remarkable and commendable accomplishment.

Could this technology be installed in the heavy TITAN Pick-up to effectively reduce fuel consumption by about 66% while increasing performance above ALL existing pick-ups?

Many would buy such very high performance vehicle, even if it cost 2X as much?

Bigger may even be Better?

I don't understand why everyone believes carbon emission of 129g/km under Euro testing would be equivalent to 42mpg under EPA.

Check the carbon emission of BMW's 3 hybrid and 5 hybrid under Euro testing - I guess the EPA rating for this Q80 wouldn't be far above 30mpg(U.S.).
