The fourth generation CR-V did not take six days to build. In fact, you can trace its ancestry back to a time when dinosaur-sized competition ruled the highway and through the time when the meteorite-like impact of rising fuel prices made those dinosaurs recede. This latest version of the Honda's smallest SUV hosts numerous updates that, when taken apart, might seem minor and inconsequential, but together they make for a vehicle that's more fuel-efficient, more powerful, and larger inside. It's the product of meticulous changes from its creator, unlike us damn dirty apes who drive it.

The improvements appear in a range between zero and 5. The 2.4-liter inline-four has 5 more horsepower and 2 more lb-ft of torque, but we challenge you to spot the difference from the driver's seat. AWD models get a fuel economy improvement of 1 and 3 mpg city/highway, thanks to a longer final gear ratio and efficiency increases throughout the powertrain. Weight has been shed in small amounts everywhere, adding up to an 139-pound decrease relative to its predecessor. The result is a CR-V that carries 1.3 fewer pounds per horsepower.

These incremental changes return likewise incremental performance benefits. Our loaded EX-L tester reaches 60 mph in 9.1 seconds, or a tenth faster than the best time we recorded from the previous generation. The difference shrinks to zero at the quarter mile, and there the CR-V is traveling 83 mph. Its 28.8-second figure-eight lap time also matches the previous gen, but most impressive is the CR-V's accurate steering, front-end response, and lift throttle-induced rotation.

Honda's decision to stick with a five-speed automatic becomes more apparent on the road. Lengthening the final drive (from 4.50 to 4.44) in the name of fuel economy does reduce engine speed at freeway cruising, but it also extends the ratio spread. While choosing one of the five long gears goes by unnoticeably in most instances, other functions -- like passing traffic or merging onto the freeway -- highlight the need for more options. The ratio spread provided from a six-speed transmission would seem a better solution, one some competitors are already using.

While Honda has added more sound-deadening material, engine noise still rings through the cabin during sustained heavy-throttle applications, as in the aforementioned on-ramp experience. The sound is traditional Honda, and it's one enthusiasts might enjoy, but that your mom probably won't. Both will agree to avoid the green Econ button. When engaged, climate controls come on less frequently, and you have access to what feels like a quarter of the gas pedal.

Similarly questionable is Honda's infotainment system, which is divided into a main 6.5-inch screen in the center of the dash and a 5-inch screen not far above. The main screen contains the navigation functions (when so equipped), audio controls, and so on, while the smaller screen shows fuel-economy data, as well as audio information and turn-by-turn prompts. While our initial response to this setup was positive ("Small Stuff," January 2012), the longer we stared at that second screen, the more it felt redundant. Why can't a larger, single screen do everything? In the Civic, the second screen is driver-oriented, sitting in clear view to the right of the speedometer. In the CR-V, it is recessed in the top center of the dash, giving the impression that it might disappear in a fight-or-flight scenario.

The rest of the interior packaging is clever. While exterior length and height have decreased, total passenger volume has increased 0.6 cubic feet and cargo volume behind the second row has increased 1.5 cubic feet. Dropping the rear seat to access that space takes one hand: Pull the strap and the bottom flips forward and the seatback drops, giving access to the rear cargo area. In another update, the outer edge of the driver's sideview mirror has a wide-angle partition, providing easy view of the blind spot.

The design of the new CR-V proves largely intelligent. We can offer only minor complaints about some odd mutations, but we can levy the same niggles at wisdom teeth. Questionable (and evolution-relevant) mutations aside, the CR-V remains a solid car in its element, a careful and mostly well-executed update of an already popular and successful product that should carry it far beyond the prehistoric age.
