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:

Previewing the 2014 Paris Motor Show

Don't let the shiny objects detract from the serious side of the show. Sales, fuel economy and regulations are part of the conversation.
The Paris Motor Show is one of the glitziest events on the automotive calendar. Yes, it helps that it's in the City of Light, but the glamorous surroundings only enhance the spectacular wares that automakers bring to the show. This is where Europeans debut their best new cars for the coming year, both as eye-catching concepts and in production trim.

2016 Lamborghini Aventador LP 750-4 Superveloce First Drive [w/video]

I'm not as fast as Peter Muller. The chief driving instructor for one of the most revered exotic car companies in the world can turn in lap times that would shame my best efforts, all while giving me notes over the radio and steering with one hand. He's quick. And still, I kept catching him, even slowing down for him, on the fast, sweeping Turn 3 at Circuit de Catalunya. On Muller's advice I held a mid-track position just past the halfway point of the corner, then tightening towards a very late apex and flat out acceleration into a short straight section. Muller was leading a $1.5-million pack of Lamborghini Aventador LP 750-4 Superveloce supercars, and driving the standard Aventador himself. Forget that the SV has added nearly 50 horsepower and dropped around 110 pounds versus the 'base' model; those are just numbers. The SV makes a hack like me as quick as Lamborghini's top trainer, for at least one glorious corner. This is a special car. It's hard to describe Lamborghini's 6.5-liter V12 masterpiece without using indulgent language. But it's the reworking of this massive engine that starts to explain my Turn 3 pace. The engine drives an impressive set of output and performance figures: 740 horsepower (the eponymous "750" figure of the model name is a metric horsepower quote), 509 pound-feet of torque, 0 to 62 miles per hour in a scorching 2.8 seconds, and a top speed in excess of 217 mph. Lamborghini president Stephan Winkelmann says the use of naturally aspirated engines is "part of our DNA." That dedication makes for a powerful differentiator in our current turbo-sodden area, and a magical experience in the case of the SV. The added output and "enriched torque curve" have been achieved by way of revised variable valve timing and intake, as well as a new lightweight exhaust system. Power comes on with authority even under a few thousand revs, and rises maniacally as long as you're inclined to keep the accelerator pegged. The V12 spins freely and fast, hammering home the need for a ultra-responsive transmission with each run up to the redline. Of course, the bellow of the car is such that I hardly needed the gear indicator on the digital tach to tell me when to shift. The V12 sounds luscious at low speeds, angry at full throttle, and absolutely murderous approaching the 8,500-rpm cutoff. Unless you're deaf you'll quickly learn when to pull on the shift paddle, while keeping your eyes on the blurring road.
