2015 Mercedes-Benz ML400 Quick Spin

Mercedes-Benz has taken a risk in its quest to downsize its engine range. For 2015, the brand's popular M-Class five-passenger CUV did away with its trusty 4.4-liter, twin-turbocharged V8, and has replaced it with a 3.0-liter, twin-turbocharged V6. It's no surprise that power is down thanks to this move. Outputs of 402 horsepower and 443 pound-feet of torque are replaced by 329 hp and 354 lb-ft, but weight is down significantly as well. The new ML400 is nearly 300 pounds lighter than the 4,982-pound ML550. Will that tradeoff be enough to satisfy a buying public that's embraced falling fuel prices by buying bigger and thirstier vehicles? To find out if the blown V6 is a suitable replacement for the twin-turbo V8, we spent a week at the helm of the all-new ML400. Driving Notes This 3.0-liter, twin-turbocharged V6 is the same engine being offered in the C400 and E400 sedans. Typical of today's turbocharged engines, peak torque is spread lavishly across the rev range, from 1,600 to 4,000 rpm. That's not as generous a spread as the ML550, which offers all its torque between 1,600 and 4,750, but the power on offer is easy to access. Importantly, the new V6 never feels flat-footed or unable to answer our commands. In fact, the ML400 feels even quicker than its six-second sprint to 60 would indicate, although it's not so fast as to challenge the 5.3-second time of the ML550. After a slight and expected bout of turbo lag, the power arrives suddenly and proceeds linearly until just south of the engine's 6,500-rpm redline. The throttle response is soft in Eco mode, as expected, but sharpens up slightly when the fuel-sipping mode is off, where the gas pedal is still easy to modulate. It's a quiet engine, too. Compared to the brawnier exhaust note of the old ML550 or the howling six-cylinder in the BMW X5 xDrive35i, the ML400's note is smooth and refined, befitting of a V6. Its turbocharged nature is instantly noticed, though. Get on the throttle and the 3.0-liter happily hisses its way up the tachometer. But, it's only when you get on the throttle hard that the engine really weighs in. In day-to-day driving and traffic its soundtrack is unobtrusive and relaxed. The EPA rates the ML400's fuel economy at 18-miles-per-gallon city and a 22-mpg on the highway. That's better than the 14 city and 19 highway of the old V8 ML, but it still seems a bit low, especially for the highway figure.

2019 BMW X7 vs luxury SUV rivals: Comparing specs and photos

Today we get our first-ever look at the first-ever 2019 BMW X7 crossover. We've actually already had our first-ever drive in an X7 Prototype. And so, we thought it appropriate to follow that up today with the first-ever X7 comparison of specs between BMW's first-ever three-row crossover with legitimate room for seven and its many high-dollar competitors. On paper, the 2019 X7 definitely seems to most closely align with the Mercedes-Benz GLS-Class. Their similar dimensions, interior space, engine choices and price would certainly imply where BMW placed the target when developing X7. We used those same elements to determine three-row vehicles likely to be cross-shopped or that should be cross-shopped. These include the Audi Q7, Land Rover Discovery, Volvo XC90 and Lincoln Navigator. Yes, the latter is a truck-based SUV as opposed to a crossover, but tell that to all the people lining out the door at the local Lincoln emporium. They do not care, and neither shall we. We also included the 2019 BMW X5, which was completely redesigned for this year and therefore not the first-ever. That makes it less appealing? Either way, lining the new X5 up with the SUV that leapfrogs it atop BMW's SUV hierarchy should provide a good idea of just how much more you get by going up a model number. Engines and model lineup Again, the X7 aligns closest with the GLS, offering a base six-cylinder in its xDrive40i model and an upgrade turbo V8 in the xDrive50i. The Mercedes engines have greater output, but the GLS still accelerates slower than the BMW. As the 2019 X5 offers the exact same engines, we would also expect the X7's fuel economy to be superior to the GLS once its estimates are announced. It should be noted, though, that the GLS offers a high-powered AMG model whereas we anticipate the X7 to offer a plug-in hybrid model comparable to the X5 upcoming xDrive45e model. The other luxury SUVs diverge in their engine choices and model lineup. The Audi Q7 offers a base turbocharged four-cylinder, as does the Volvo XC90 in its T5 model, which we left out of the above chart entirely for space reasons. That the Q7 3.0 TFSI supercharged V6 gets the same fuel economy estimates as the four-cylinder is proof positive that engine is purely around for its lower base price.

Lewis Hamilton blasts to pole position for British Grand Prix

SILVERSTONE, England - Lewis Hamilton took pole position for his home British Grand Prix for the third year in a row on Saturday with a sensational lap that left him one step away from Michael Schumacher's Formula One record. Hamilton's championship-leading Ferrari rival Sebastian Vettel, who has a 20-point advantage after nine of 20 races, qualified third. The Mercedes driver was half a second quicker than Ferrari's second placed Kimi Raikkonen and his time of one minute 26.600 seconds was so outrageously quick there were gasps before the crowd erupted. "I always try to leave the best to last," the Briton told retired champion Jenson Button in post-qualifying interviews on the grid. "I had to make sure I got that lap in. I couldn't do it last weekend (in Austria) so I made sure I could here." Hamilton still faced a nervous wait after race stewards announced they were investigating an incident involving French driver Romain Grosjean, who complained he had been blocked earlier in the session. They swiftly decided to take no further action. The Briton's mastery of a damp but drying track lit up an overcast afternoon and the pole was the 67th of his career, sixth of the season, and gave him every chance of equalling Schumacher's record 68 before the August break. The triple world champion has won the last three British Grands Prix and can equal the late Jim Clark's feat of four home wins in a row, and five in total, on Sunday. Saturday ensured he has already matched Clark's 50-year-old record of five British Grand Prix pole positions. "I feel amazing in front of a great crowd like this. I hope you liked the lap," Hamilton told the grandstands full of cheering fans. "I generally like it to be dry, but I like it when the conditions are tricky." Hamilton's Finnish team mate Valtteri Bottas, winner in Austria, was fourth fastest but has a five-place penalty following a gearbox change. That promoted Red Bull's Dutch teenager Max Verstappen, who has suffered five retirements in the last seven races, to the second row. Renault's Nico Hulkenberg and his former Force India team mate Sergio Perez filled the third row. There was good news for beleaguered McLaren, who raised a cheer when Fernando Alonso made the most of improving conditions to set the fastest time in the first phase of qualifying, with Belgian Stoffel Vandoorne qualifying ninth.
