Ecclestone wonders if F1's upcoming turbo V6s should get augmented sound [w/videos]

While every team on the Formula One grid is worried about making a good showing in this year's championship at the same time as they develop a brand-new car for next year's championship, Bernie Ecclestone and F1 circuit promoters have a different concern: how next year's cars will sound. The current cars use 2.4-liter, naturally-aspirated V8s that can reach 18,000 revolutions per minute and employ dual exhaust, next year's engine formula calls for 1.4-liter turbocharged V6s that are capped at 15,000 rpm and are constrained to a single exhaust outlet. Ecclestone and promoters like Ron Walker believe the new engines sound like lawnmowers and that the less thrilling audio will keep people from coming to races. If Walker's Australian Grand Prix really is shelling out almost $57 million to hold the race, every ticket counts. As a fix, according to a report in Autoweek, Ecclestone "suggests that the only way to guarantee [a good sound] may be to artificially adjust the tone of the V6s."
However, neither the manufacturers nor the governing body of F1, the FIA, think there will be a problem. Ecclestone fears that if the manufacturers "don't get it right" they'll simply leave the sport, but the only three carmakers and engine builders left next year, Renault (its 2014 "power unit" is pictured), Mercedes-Benz and Ferrari are so embedded that it would stretch belief to think they'd leave the table over an audio hiccup - if said hiccup even occurs. And frankly, these issues always precede changes to engine formulas, as they did when the formula switched from V10 to V8; fans, though, are probably less focused on the engines and more on the mandated standardization of the sport and the spec-series overtones that have come with it.
No one knows yet what next year's engines will sound like, but we've assembled a few videos below to help us all start guessing. The first is an engine check on an Eighties-era John Player Special Renault with a 1.5-liter V6 turbo, after that is Ayrton Senna qualifying in 1986 in the Lotus 98T that also had a 1.5-liter V6 turbo, then you'll find a short with a manufactured range of potential V6 engine notes, and then the sound of turbocharged V6 Indycars testing last year at the Indianapolis Motor Speedway. Any, or none of them, could be Formula One's future.

Carlsson SLK 340 Judd is winged up for hill climb glory

Carlsson has been expertly tuning Mercedes-Benz products for more than 20 years now, but we can't say as we remember the outfit turning out anything quite so racy as this SLK 340 Judd that it has brought along to the Geneva Motor Show this year.
This SLK is meant for competition, obviously, and Carlsson has already booked the car to race in several hill climb events in the E1 category. The purpose-built racer should have a fighting chance to do well in said races, with a shape vetted in wind tunnel testing for maximum downforce, the SLK uses a carbon-fiber bodyshell to help achieve a curb weight of just about 1,720 pounds.
The featherweight SLK's name comes from its 3.4-liter V8 engine, which churns out a wicked 610 horsepower to go with its 317 pound-feet of torque. A Hewland transmission with paddle shift operation manages all of the thrust.

2014 Mercedes-Benz S-Class interior caught in spy shots

With the redesigned 2014 Mercedes-Benz S-Class getting closer to production, the camera-wielding crew over at Autospies somehow managed to get inside of the car to snap some detailed spy shots. As the prototypes continue to shed camouflage, it would appear that Mercedes-Benz is getting closer to unveiling the car, and with the Geneva and New York auto shows coming up, it could be sooner rather than later.
From what we can see of this car's interior, the overall look of the S-Class' cabin isn't a ground-breaking departure from the current car, but it has been completely redesigned with more advanced technology. The styling is now even more upscale with larger swaths of wood, more shapely door panels (without the built-in armrest cubbies) and the concept-like two-spoke steering wheel. The highlight of this car though is probably the two massive digital screens with one being used for driver information and the other used for navigation, audio and infotainment systems. One other detail we noticed about this car is that it was equipped with the new 360-degree camera that debuted on the new GL-Class and will also be used on the 2014 E-Class. We also know that the next-gen S-Class will be getting the new cloud-based MBrace2 infotainment system.
As for the exterior design, it looks like the next S-Class will carry a similar profile as the current car, but we can see through the camouflage that the new styling will fit in better with current Mercedes-Benz products. Up front, the grille is much larger is flanked by aggressive LED-trimmed headlights, while the rear view of the car shows us the LED brake light now at the top of the rear window, a more pointed trunk opening and a more squared-off rear fascia with exhaust outlets pushed to the corners.
