A look inside Infiniti's variable-compression engine

We're sympathetic to anyone who had trouble understanding what's going on with Infiniti's new variable-compression engine. While we got a full tech briefing on the novel VC-Turbo back in August, the visual aids were lacking. The cutaway engine Infiniti brought to the Paris show fixes all of that. You can thank the little green and pink lines on the cutaway for making the whole idea a little more clear. Click through the gallery to see two lines – one green and one pink – that represent the different strokes allowing for different compression ratios. Remember, the compression ratio is the amount of volume in the cylinder on intake compared to the amount at the end of the compression stroke. Leave more room at the end and you lower that ratio. The length of the stroke doesn't change with this system, but where it sits along the cylinder does. Hence those two lines. The variable compression ratio allows this new turbocharged engine to maximize fuel economy when the turbo isn't needed by raising the compression ratio. It will see its first use in the next Infiniti QX50 crossover, previewed by the QX Sport Inspiration concept that's also on display in Paris, and has performance targets of 268 horsepower and 288 pound-feet of torque. After, it will migrate to other Infiniti and Nissan vehicles, with transverse front-drive-based applications first in line. Eventually, it's likely to completely replace Nissan's corporate 3.5-liter V6. We'll be poking around the engine a little more in Paris today to try and get some more info. For now, enjoy those cutaway images and those friendly little lines.

Renault gets a 'wake-up call' — a record $8.6 billion loss

PARIS — French carmaker Renault said it had been given a wake-up call on Thursday with a record net loss of 7.29 billion euros ($8.6 billion) in the first half of the year, inflicted by the COVID-19 crisis and troubles at its alliance partner Nissan. Global automakers have been hit hard by the coronavirus pandemic, which has shuttered factories and kept many customers away from car dealerships. But the Renault-Nissan alliance has been hit especially hard as it was already weakened by low margins and boardroom turmoil surrounding Carlos Ghosn, the architect of the alliance who was ousted in 2018. Renault shares were down 3.3% when trading opened in Paris. "Today's results will be a disturbing wake-up call," CEO Luca de Meo, the former Volkswagen executive who started at Renault this month, said on a call with analysts. "We are currently touching the bottom of a negative curve that started several years ago, and probably even earlier," de Meo added. "We are in a complex, difficult situation. We all are. But ... we were already, I would say, feverish. So for sure it is even harder for us." De Meo said the company would now double down on a previously announced turnaround plan, laying off thousands of workers, reducing the range of models, and improving cooperation between alliance partners on vehicle production. He said a team of 40 senior executives from across Renault was cloistered on the top floor of the company's headquarters in Boulogne-Billancourt near Paris, working on details of a strategic plan which will be presented in January at the latest. He said his focus would be pushing the Renault brands that can deliver profits — especially compact cars, SUV crossovers, and electric and hybrid vehicles — and shifting emphasis from volume to value. "We know what we need to do," de Meo said. "Better times are waiting at the end of this twisty road." Renault said group operating losses, factoring out the effect of Nissan's losses, reached 2 billion euros in the first half, compared with operating income of 1.5 billion last year. Sales slumped 34.9%, a result the company attributed mainly to the global COVID crisis and Renault burned through $6.38 billion in cash over the first half. Nissan Motor Co this week warned of a record $4.5 billion operating loss this year and its lowest sales in a decade. Its negative contribution accounted for 4.82 billion of Renault's net losses, the French firm said on Thursday.
