Now in its second year of production, the Nissan Cube receives a number of updates for 2010. While the base 1.8 trim remains unchanged, the mid-level S and upper-end SL trims now come equipped with such standard features as Bluetooth and a leather-wrapped steering wheel with audio controls. The S trim also receives an iPod interface and speed-sensitive volume as part of its standard audio system. In addition, the upscale 1.8 S Krom Edition receives a new 4.5-inch color audio display with a USB interface and a rear-view camera, as well as a Nissan Intelligent Key with push-button ignition, which all come standard for 2010. A 1.8-liter, DOHC four-cylinder engine powers all four Cube trims. The engine features variable valve timing for improved efficiency and produces 122 hp and 127 lb-ft of torque. It drives the Cube's front wheels through either a six-speed manual transmission or an Xtronic CVT (Continuously Variable Transmission), which delivers smooth shifts, according to reviewers. The EPA estimates fuel economy numbers for the engine at 25/30 mpg with the manual shifter and 27/31 mpg with the CVT. The aptly named Cube continues to stand out from the crowd, thanks to its tall, boxy shape and its unique asymmetrical wrap-around rear window. Nissan says the Cube's front grille was inspired by a bulldog wearing shades, and gives the windows a distinctive trim treatment for a photo-frame appearance. All trims include privacy glass, while the SL trim comes with automatic on/off headlights as a standard feature. The S Krom Edition sports such features as unique barred upper and lower front grilles, body side sills, fully integrated front and rear bumper fascias, and a rear roof spoiler, all of which set it apart from the other Cube trims. The Cube's design not only makes it distinctive, but also results in a roomy, functional interior. It seats up to five passengers, with manually adjustable front seats and a sliding/reclining/fold-down rear seat, adding to the Cube's versatility. The curvy dash ripples across the front of the cabin, while above, concentric circles emanate from the overhead light, creating a "water drop" affect. With the rear seat folded down, the Cube offers a respectable 58 cubic feet of storage space. A side-opening, refrigerator-style rear door provides easy access to the cargo area. All Cube trims come well-equipped with all the basics, including air conditioning, power windows and door locks, a multi-function trip computer, remote keyless entry, a tilt steering column, cargo tie-downs, six cupholders, and five bottle holders. The S and SL trims add such features as a leather-wrapped steering wheel, Bluetooth, cruise control, map lights, and chrome handles, while the SL trim also includes automatic temperature control. An AM/FM audio system with a CD player and an MP3 input jack keeps passengers entertained in all trims, although the two-speaker system in the Base 1.8 trim upgrades to a six-speaker system in the S and SL. All trims come with cloth upholstery, although the S and SL receive premium cloth seats. The S Krom Edition adds a custom interior with exclusive black and gray seats, aluminum-trimmed pedals, and a Rockford Fosgate audio system with a subwoofer, among other features. Owners can customize the Cube with a wide range of options, such as splash guards and a shag dash topper, available on all trims. Options available only on the S, SL, and S Krom Edition include a cargo organizer, 20-color interior accent lighting, illuminated kickplates, and an exterior Aero Kit, which adds a front chin spoiler and a rear underbody spoiler, as well as body side sills and a rear roof spoiler. Standard safety equipment includes six airbags and antilock brakes with brake assist and electronic brakeforce distribution. The base 1.8 and S trims ride on 15-inch steel wheels, which the SL and S Krom Edition upgrade to 16-inch aluminum-alloy wheels.
