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.

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).

Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.
