Nissan's Cummins tie-up bears first fruit with Frontier Diesel Runner concept

The 2014 Chicago Auto Show is proving to be a surprisingly big show for alternative fuels. The Chevrolet Silverado HD pickups are getting a compressed natural gas option and the refreshed BMW X3 is receiving a diesel engine, as is the German automaker's 7 Series. You can add one more oil burner to the mix, at least in concept form: Nissan has released its Frontier Diesel Runner Powered by Cummins with a 2.8-liter, four-cylinder turbodiesel engine and an eight-speed automatic transmission from ZF.
While Nissan calls the Cummins-powered Frontier a concept, it's really just a Frontier DesertRunner 4x2 with a diesel engine replacing the standard 4.0-liter V6, and it's meant to gauge consumer interest for a diesel option in the next-generation Frontier. Nissan has clearly noticed that Chevrolet will be offering a diesel in its new Colorado and wants to see how buyers will react to a mid-size alt-fuel pickup from a Japanese brand.
Exterior modifications to the concept are minor. To show off the engine, there is a transparent hood insert and the pickup has been painted in a two-tone finish of high-gloss red and matte silver edged in carbon fiber trim. The interior gets the same combo of red, silver and carbon fiber to match the outside.

Nissan Juke facelift spied during testing

The Nissan Juke boldly reinvented the subcompact crossover for the modern age a decade after the niche's progenitors - the first-generation Toyota RAV4 and Honda CR-V - grew well beyond their original, diminutive sizes. Since being introduced in 2010 as a 2011 model, the Juke has proven to be a huge sales success for Nissan in Europe and quite a success here, too. A modest refresh is planned for the 2015 model year of Nissan's tiniest crossover, and our spy shooters have caught an early glimpse.
The exact changes are not easy to spot, but you can bet that anywhere you see camouflage, a modestly new look is hidden underneath. The biggest change up front is the narrower grille that appears to no longer extend over the headlights. Assuming this isn't just a clever disguise, the change gives the impression that the Juke actually has distinct headlights, instead of massive fog lights. The more angular front air dam also appears to extend slightly lower than before, and the intakes appear to be revised as well.
The changes to the rear are even more minor. You can still see the outlines of the boomerang-shaped headlights, and any alterations to the rear bumper are impossible to spot behind the camouflage tape. It's also unclear at this point whether the interior will receive any refinements or new options.

Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.
