While Land Rover made a splash in Los Angeles with the new five-door Evoque, back in its native UK, the company was casting a white light and a dark shadow over the go-anywhere Discovery 4/LR4.

Presented as the new Landmark edition, the special Disco can be ordered in either Santorini Black or Fuji White with coordinating interior in either ebony or ivory – the latter being offered for the first time in a Discovery. To complement the stark exterior color, Land Rover has also given the grille, roof rails and 20″ alloys a darker finish and fitted it with tinted glass.

The Discovery 4 Landmark is powered by a twin-turbo diesel V6, and comes packed with all the features you’d expect from a Land Rover, plus a little touch of the exclusive. Details in the press release after the jump and photos in the gallery below.

Whoops! MT discovers Ford Edge Sport slower than less powerful SEL model

2011 Ford Edge – Click above for high-res image gallery

According to popular American folklore, you should always buy the biggest engine available. Such thinking likely became prevalent in the 1950s, when the American automotive industry was busy building new V8 engines, experimenting with multiple carburetors and high compression, and generally discovering the art of hot-rodding. Gas prices? Fuel economy? Pfft. It was a great time to be an American.

These days, life isn’t quite so simple. There are countless reasons to consider a downsized powerplant. First off, we all care about fuel mileage and many of us care about emissions. Then there’s the cost consideration, and, finally, the biggest engine isn’t always the best performer. Proof of such can be seen in the new 2011 Ford Edge, that we just drove ourselves and that was recently put through the full testing regime by the boys at Motor Trend.

There are currently two V6 engines available in the Edge (a 2.0-liter EcoBoost is on the way in a few months), a 3.5-liter and a 3.7, which comes straight from the Mustang. Power for the smaller engine comes in at 280 horses and 253 pound-feet of torque. The larger 3.7 puts out 305 horses and 280 lb-ft and is available only in the Edge Sport. So, the Sport is the fastest, right?

Not so fast… literally. MT clocked a 7.1-second run to 60 in the base Edge, but only managed a disappointing 7.6 seconds in the 3.7-powered Edge Sport. Apparently, the problem is weight. The base Edge tipped MT’s scales at 4075 pounds while the Sport came in at an obese 4405, part of which can be explained by the addition of all-wheel drive. In any case, the Edge Sport, with its massive 22-inch wheels and wide tires, can’t keep up with the base Edge in a straight line.

On the flip side, the AWD Edge Sport (with those aforementioned oversize wheels and tires) handily out-handled its base model sibling. In other words, this is a case where you need to pick your poison, either handling or straight-line acceleration. And of course the upcoming EcoBoost will add another interesting option to consider in a few short months.

GM discovers flaw with HD pickup hill-hold assist, fast-tracks fix

Filed under: Truck, Safety, Technology, Work, Chevrolet, GM, GMC

Last week, PickupTrucks.com held one of its periodic load lugger shootouts where it brings together the heavy haulers from General Motors, Ford and Chrysler to see which pickup truck is the top dog. After running acceleration tests at Milan dragway, editor Mike Levine and the crew moved the fleet of nine trucks to the GM Proving Ground in Milford, MI. During towing evaluations on the 7.2 percent hill, Levine discovered an issue on the Chevy Silverado 2500 while the gas-engined 3/4 ton truck was towing 10,000 pound trailers up the hill.

The GM trucks incorporate a hill-hold feature into the stability control system. Hill-hold is supposed to detect when the vehicle is on an incline with the brakes applied. When the driver releases the brake pedal, the valves in the stability control unit retain the pressure in the brake lines for up to 1.5 seconds. Once the timer expires or the driver applies the accelerator, the valves release the brake pressure.

During testing, Levine discovered that the system was not holding the pressure on the 7.2 percent hill for any of the GM trucks and notified the engineers on hand. Oddly, a later test found that the system was working properly on the steeper 16 percent grade. GM engineers investigated the issue with engineers from system supplier TRW and found an incorrect calibration value in the control software for the accelerometer used to detect inclines. This prevented the system from correctly detecting the smaller hill.

The code was corrected and updated software began rolling out to the production line this past Monday, July 19. The same software update is also going out to dealers so that trucks in stock on lots and in for service can also be updated. GM is still considering whether to issue a recall or a technical service bulletin for trucks that have already been delivered to customers.
