In response to our confusion over engine specs for the new 2011 Nissan Quest, Nissan’s product communication team wrote in to let us know that

At our media preview we received the new torque and hp figures during the middle of the event of 240 and 260 respectively but for some reason the rpm figures [in promotional materials] weren’t updated.

Thanks to Nissan’s prompt response, we can now officially report that the confusion is over. Engine power specs for the 2011 Nissan Quest are as follows

Horsepower : 260 hp @ 6000rpm

Torque (lb-ft) :  240 lb-ft @ 4400rpm

Going over Nissan’s specifications for the 2011 Quest minivan, I came across these for the engine, on both the media and the consumer site:

260 horsepower @ 5,200 rpm

240 foot-pounds @ 4,800 rpm

Some non-Nissan sites provide slightly different numbers:

253 horsepower @ 5,200 rpm

236 foot-pounds @ 4,800 rpm

So perhaps Nissan recently found a couple more horsepower then rounded both figures up to the nearest five.

Both sets of numbers instantly struck me as impossible.

When I attended the launch of the Buick Regal, Buick’s product reps were anxious to talk all about the forthcoming Buick Regal GS, the high-performance version of the Opel Insignia-based sedan. At the time, the Buick Boyz were anxious for input; what, they asked, would enthusiasts prefer: a manual transmission or all-wheel drive. My answer: all of the above. Surely, I thought,  Buick would be bringing a rebadged version of the Opel Insignia OPC, with AWD and the GM 2.8T V6 from the Cadillac SRX Turbo and Saab 9-5 Aero. No, came  the answer. The 2.8T was not approved for use in a Buick. Stung by past oversharing between divisions, GM had decided that the 260-325 HP, Australian-built LP9 engine would be limited to applications in Caddys and Saabs. But now, it seems that GM may have penned some kind of deal with Saab, as GMInsideNews reports that the LP9 has been discontinued from its last remaining Cadillac application, the SRX Turbo.

When Chrysler re-launched under Fiat, its Five Year Plan called for the Italian automaker’s dual-clutch transmissions (known at Fiat as Twin Clutch Transmission, or TCT) to make their way to the group’s D-segment models by the end of 2010. But here we are, at the end of 2010, and the Chrysler 200 and Dodge Intrepid have not been equipped with the fuel-saving transmissions. So what’s the deal? The only news on the topic comes from InsideLine which reports

By 2013 this TCT gearbox will be offered with all inline-4 and V6 engines from Fiat and Chrysler in North America. The aim is to have C-plus and D-segment cars like the Chrysler 200, V6-equipped Jeep models, and future Alfa Romeo Giulia lead the way with the TCT gearbox here.

But starting when? And with what vehicles? With Ford already offering dual-clutch transmissions in the Fiesta (with more to come), and Hyundai about to bet big on dual-clutch boxes next year, Chrysler is on pace to lag two years behind the market leaders. For a brand in Chrysler’s position, that’s a recipe for perennially playing catch-up on a crucial technology.

Is it a coincidence that, on the day the newswires fill up with reports of renewed cooperation between Aston Martin and Daimler’s Maybach brand, the British sportscar firm has released a video with the theme “one engine, one ethos”? After all, before Aston built a hideous concept on the Mercedes GL platform and Maybach asked Aston to develop a four-door concept, the assumption was that Aston wanted Mercedes engines to replace its aged Cologne-built V-12. Now, possibly motivated by Lotus’s engine flip-flop, it seems that Aston is taking pride in its elderly but unique 12-banger. Which seems like a smart move: high-end buyers often care more about pedigree than absolute performance, and being seen as an independent house rather than an engine customer shop certainly helps cultivate that image… even if it means sticking with an engine that’s based on a pair of Ford V6s. Especially when those two V6s sound so damn enchanting.

It’s hard to believe that The General was once so dominant that it sweated over the fear of being split up by the federal government via antitrust regulations, and that GM’s divisions cranked out more than 25 separate passenger-car engine types (counting Opel and Holden models) during the decade. Why, The General boasted ten different car V8s during the 1960s (not counting earlier models intended for warranty replacements, industrial use, etc); eight of those engines were being built in 1965 alone. Imagine a manufacturer today so mighty that it could offer eight totally different V8 engines (in 14 displacements) for sale in its new cars! (Read More…)

Lotus has perplexed and antagonized a number of auto enthusiasts by announcing its intent to expand beyond niche sportscars and become a global sport-luxe brand in the vein of Porsche and Ferrari. By announcing five future cars at once, Lotus made an audacious splash in the industry, and painted a giant target on its back. At the same time, Lotus’s initial plans called for the use of Toyota V8s and hybrid systems, leading some to wonder if Lotus was even being audacious enough. After all, assuming it could play with Porsche’s and Ferraris using only mass-market customer engines was somehow cravenly conservative to the point of being obnoxiously ballsy. Surely Lotus realizes that bespoke drivetrains are crucial to building a global sportscar brand? Well, apparently the Hethel boys didn’t get it… at least until their potential customers made an issue of it.

Ford currently offers four vehicles with its EcoBoost-branded direct-injection, turbocharged V6: Taurus and Flex, and the Lincoln MKS and MKT. But what percentage of buyers do you think spends the $750 to $1,700 to upgrade to Ford’s engine technology of the future? Write down your guesses and hit the jump to see how close you were…

When Autoweek asks the R&D boss at an alt-drivetrain leader like Toyota what the future of its powertrain development looks like, one tends to hope for something revelatory in his answer. Instead, we get

Conjecture that Lambo might be getting rid of the V12 in its flagship turns out to have been way off-base: in fact, Lamborghini has just announced specs for its first clean-sheet V12 since the 1964 350GT. Its 6.5 liter displacement is good for 700 high-revving horsepower (but “only” about 500 lb-ft of torque), thanks to aluminum-silicon alloy four-valve heads and an oversquare design. The new engine also comes with a new type of automated-manual gearbox that Lamborghini calls an “Independent Shifting Rod” transmission. We’ll publish more technical details as they become available, but for now let’s just take a moment to lap up the visual feast. New Lambo V12s don’t come around every day… in fact, given past practice and future emissions standards, this may well be the last of the breed.

Recently, I wrote about how Tata is reaping huge profits thanks to the acquisition of the “toxic” JLR brands. It was a huge gamble to buy them, but it paid off. Literally. Well, it appears that Tata’s growing profits are going to benefit not only Tata, but ironically, Ford, as well. (Read More…)

We’ve already been impressed enough with the McLaren MP4-12C’s 3.8 liter turbocharged V8 to say it “looks like mechanical sex” and give it its own gallery. The super-compact, direct-injected engine develops in the neighborhood of 600 hp, giving the new McLaren the dangly bits to show a (similarly-priced) Ferrari 458 the way around a racetrack. And though McLaren clearly thinks the MP4-12C’s race-tested abilities will help build its brand into the new race-nerd standard, it’s also beating Ferrari at a new game that will become increasingly important with time: the C02-per-horsepower game. Ferrari’s 570 hp V8 emits 320 grams of C02 per kilometer, giving the Fezza a rating of .56 grams of C02 per km per horsepower. McLaren’s goal for its not-quite finalized MP4-12C drivetrain is a C02 emissions rating of below 300 gm per km, which would give the supercar closer to a .5 gram per km per horsepower rating. And though the direct-injected, downsized and turbocharged engine helps keep that number down, the MP4-12C’s dry weight is also 176 lbs lighter than the 458’s (2,866 versus 3,042).

I have another Ford Duratec question for Sajeev, knowing his enthusiasm [So to speak – SM] for this engine. My 12 1/2 year old daily driver, my first “real” car that I have been driving for 2/3 of my driving years – a ‘98.5 Contour SVT – has a major problem.

I was at Summit Point on Friday, and had oil starvation-no warning-just puff of smoke out exhaust, a loss of power and a noise, then engine quit – clutch in rolled off track just in time for oil to start gushing out.  Oil kept dripping the next hour or two.  Cannot visibly see damage, but dipstick is stuck.  Mechanic today (5 days later) tried to turn over the engine to see if it would spin and if compression – said no compression and it spun a few times then he heard a bang and it locked up.  Did zero disassembly.

Question 1 – is that an appropriate way to see if an engine is done for, especially knowing there is no oil in the crankcase?

Question 2 – is it worth finding someone to do a 3.0 upgrade (I don’t have the expertise, knowledge, time, or place to even fathom taking this on)?

I’m going drifting. I’m going drifting dressed in the finest English brown velour ever to roll out of Dagenham, England. I’m going drifting in what this week’s Curbside Classic should have been, a 1983 Ford Sierra. And with that, I rejoin TTAC after a long hiatus due to our wonderful country sending me to various deserts to hunt for Osama bin Laden.

I have survived, although my Hilux did not after one ill-placed Taliban rocket sent shrapnel through the radiator. I also relish returning to write for one of the finest audiences I know, the Best and Brightest.

We’ve hosted our fair share of diesel skepticism over the years here at TTAC, but the latest data on diesel take rates indicate that oil-burners are more popular than you might think. Dieseldriver.com broke down sales of every passenger vehicle with a diesel option, and found an overall take rate of 32 percent over the first three quarters of 2010, and trending upwards. In the third quarter, over half of the two Audis with diesel drivetrains optional were ordered as oil burners, and the vast majority of Jetta Sportwagons sold are diesel-powered. And no wonder. Modern diesel engines can be glorious things, offering gobs of torque, shocking levels of refinement and great fuel economy. Diesel prices may have climbed somewhat in the last year or so (it’s no longer cheaper than gas), but they’re close enough to make diesel a real option. Well, at least for buyers of German cars.
