Audi R8, Lamborghini Huracan could get twin-charged five-cylinder

Engine downsizing and forced induction are some of the biggest trends in automotive powertrains today because. They offer the chance to reduce emissions and boost fuel economy, while possibly maintaining power. The shift is already happening to performance cars with turbocharged four-cylinders finding their way into the Ford Mustang, Chevrolet Camaro, and future Porsches. Now, there are rumblings of a tiny chance for a similar change coming for the Lamborghini Huracan and Audi R8. Why the new powertrain? China. While the market there might have slowing growth, it's still a major country for auto sales. The annual taxes on cars there also happen to be based on engine displacement, and there's a 40 percent rate on those over 4.0-liters, according to Car and Driver. The obvious answer to this conundrum is to build a smaller displacement, forced induction engine for the R8 and Huracan. Car and Driver points to the new turbocharged and electrically supercharged, 2.5-liter inline five-cylinder from the recent Audi TT Clubsport Turbo concept as a possible solution. Audi's e-turbo technology runs off a 48-volt electrical system and lithium-ion battery to produce a total of 600 horsepower and 479 pound-feet of torque in the prototype. With this mill, horsepower would barely shrink compared to the R8 V10 Plus and Lambo, but it actually makes more peak torque than their 5.2-liter V10s. While this is all theoretically feasible, take the possibility with a big grain of salt for now. According to Car and Driver, Quattro GmbH's Stephan Reil says that there's no work currently underway to fit the twin-charged five-cylinder, "but it has been talked about." That means such a vehicle is likely years away, if ever. In the meantime, a diesel version of the e-turbo setup is on the way the in the SQ7. Related Video:

Lamborghini highlights Aventador successor's carbon fiber chassis

Earlier in March 2023, Lamborghini detailed the gasoline-electric hybrid drivetrain that will power the Aventador's successor. We still don't know what the model (which is called LB744 internally) looks like, but the firm revealed one way it kept the hybrid system's weight in check. Lamborghini built the LB744 around a new chassis called a "monofuselage" that consists of a carbon-fiber monocoque and a front structure made with Forged Composites, an innovative material the company has used since 2008. While the now-retired Aventador featured a carbon-fiber monocoque as well, its front structure was made with aluminum. Switching to a composite structure unlocks many advantages: It's 20% lighter than the Aventador's front structure, and it helps make the overall monofuselage 10% lighter than the Aventador's chassis. Out back, the structure that the engine, the transmission, and parts of the hybrid system are mounted on is built with high-strength aluminum alloys. It incorporates a pair of hollow castings that the rear suspension system's shock towers and the powertrain's suspension system are integrated into. Here again, this layout saves weight by reducing the number of parts that need to come together to assemble the car. Power for the LB744 comes from a gasoline-electric plug-in hybrid drivetrain that consists of a new, 6.5-liter V12 engine located directly behind the passenger compartment, an eight-speed dual-clutch automatic transmission mounted transversally behind the engine, a small electric motor integrated into the transmission, two electric motors on the front axle (one per wheel), and a 3.8-kilowatt-hour lithium-ion battery pack housed in what was previously the transmission tunnel. The system's total output checks in at 1,001 horsepower. This layout delivers through-the-road all-wheel-drive, meaning that there's no mechanical connection between the front and rear axles. Lamborghini will unveil the LB744 in "a few weeks." Related video: This content is hosted by a third party. To view it, please update your privacy preferences.

Lambo to quarantine twin-turbo V8 to Urus

Lamborghini is planning to slot a 4.0-liter twin-turbo V8 into the Urus sport utility vehicle. But don't expect the engine to make its way into the Italian firm's supercars anytime soon. According to the latest report, that forced-induction mill will be limited exclusively to the sport ute for the foreseeable future. Speaking with Autocar, CEO Stephan Winkelmann reiterated that the Urus will be the only Lamborghini model powered by the turbo eight. "On the supersports cars we are convinced that the choices we have made with the naturally aspirated engines are still the right ones," said Winkelmann. "We are not saying that future engines will never beat what we have in our cars; we are saying as long as there is nothing that is better, especially at low revs or in terms of the sound that the V10 and V12 have, we stick to them." While its rivals have embraced turbocharging, Lamborghini has been a steadfast holdout for high-revving, naturally aspirated engines with two-digit cylinder counts. Ferrari, for example, has slotted a turbocharged V8 into both the California T and 488 GTB. McLaren uses a turbo V8 in all its models. Lambo's own sister brands Porsche and Bugatti also use turbochargers. But the Huracan eschews forced induction for an atmospheric V10, as does the Aventador for a V12. The Volkswagen Group of which Lamborghini is part employs a 4.0-liter twin-turbo V8 for both the Bentley Continental and numerous Audi models. We'll likely be looking at a version of this engine to power the Urus, which is also expected to offer additional powertrain options in the future. The last time Lamborghini offered an SUV was with the LM002 of decidedly different orientation, powered by a version of the V12 engine from the Countach. Related Video:
