Mercedes Predictive Cruise Control Uses GPS to Save Fuel

Honda Develops the First Traffic Jam Preventer?
Honda Motor Company today announced a computer program that prompts a driver to change behavior if it has the potential to cause traffic jams. Honda knows what traffic engineers know and commuters endure – the acceleration and deceleration behavior of one vehicle influences the traffic pattern of trailing vehicles and can trigger the traffic jams. (Nothing about road hogging SUV driver’s whose super-sized vehicles prevent trailing car drivers from judging and responding to traffic ahead since all the driver of the car behind can see is the SUV driver talking or texting on his cell phone until he jams on his brakes.)

SAE 2012 World Congress Opens in Detroit Tomorrow
Engineers who are developing the next generation of vehicle technologies, will make sober assessments of where they actually are in increasing fuel economy, decreasing emissions and combating global warming, as opposed to the sometimes farcical claims in gushing press releases from politicians and automaker p.r. departments.

Corrosion Recall Covers More than 265,000 Jeep Liberty SUVs
The suspension failure investigation was upgraded by NHTSA to a more serious engineering analysis covering 2004 and 2005 models last September. It appears from publicly available documents that Chrysler resisted the recall, doing so only after a meeting with safety regulators in February. The recall to replace all the suspension arms is expected to begin in April. Continue reading

Camaro, Corvette Auto Transmissions Faster than Manuals
The latest evidence against manual shifting comes from Chevrolet whose paddle shifter automatic transmissions on Camaro and Corvette models in 2012 have a new software algorithm that improves tap response time ~60% compared to the previous system. As a result, the 2012 Camaro ZL1’s six-speed automatic transmission has a 0-60 time of 3.9 seconds – a tenth of a second faster than GM’s official manual transmission time. Continue reading
Mazda Tribute Recall Follows Ford Escape Defect for Fires
Mazda is recalling 2001-2002 Mazda Tribute SUVs because the master cylinder cap can leak brake fluid, corrode an underhood ABS wiring connector and possibly start a fire. The recall follows one announced by Ford two weeks ago for the same safety defect on Escape SUVs, which mechanically are the same as Mazda Tributes. Like Ford, Mazda said it will tell owners to park their vehicles outside until parts are ready. Continue reading
Volt Fire Hearings Pits Ideologues versus Engineers
In the end how you view this low-voltage Congressional short circuit – with lots of smoke but no fires – depends on how you view Obama Administration actions that used taxpayer-funded subsidies to encourage production of the Volt. These include $151.4 million in stimulus funds for LG Chem, which produces lithium-ion polymer battery cells for the Volt, and $105 million given directly to GM, as well as an end-user federal tax credit of up to $7,500 per Volt purchased. Such subsidies will likely be hotly debated for all industries during the election. Continue reading

NRC Agrees Toyota Unintended Acceleration Mechanical – but NHTSA Didn’t Address Auto Electronics Safety Concerns
One simple step – the requirement of electronic data recorders that would show the actual driver or computer inputs immediately before and during an accident – doesn’t appear immanent. While this will end many false accusations used by product liability attorneys to garner huge fees from large lawsuits against automakers, there appears to be little appetite for the reform in lawyer- dominated Washington.

NHTSA Keeps Chevrolet Volt Battery Fire Probe Open
GM said this morning that it was “optimistic” that no recall would be required, a politically sensitive issue since the federal government, which NHTSA is part of, still holds a large 27% stake in GM. For GM’s part, a safety recall is arguably more damaging to the reputation of the Volt than the proposed customer service action. Last year Chevrolet sold 7,671 Volt models , which cost more than $40,000 without taxpayer subsidies to its mostly rich buyers, another political controversy in itself. Continue reading
GM Changes Chevrolet Volt to Protect Battery to Stop Fires
It was not immediately clear whether NHTSA would require that Chevrolet Volt EVs be recalled or whether the modifications can be done as a customer satisfaction procedure. There remains at this moment an ongoing NHTSA engineering analysis, which could lead to a recall. GM said it was “optimistic” that no recall would be required, a politically sensitive issue since the federal government still holds a large stake in GM. Continue reading
Milestones: 5 Million Bosch Start-Stop Systems
Volkswagen explored this concept with demonstration units decades ago. However, the effectiveness of electronic controls monitoring such variables as battery state of charge and engine temperature and heater operation, makes stop-start systems viable with no negative aspects. Stop-start is virtually undetectable to drivers, except for a slight shudder on engine reactivation. Once you drive a vehicle with start-stop you will go crazy when idling and realizing that you are getting zero miles per gallon for no reason other than to make oil companies wealthier.

New 2.0-Liter Turbo Engine Debuts in the Cadillac ATS
The Cadillac version of GM’s new powerplant will be one of highest specific output automotive engines, bar none, and more than 20% higher than the next closest competitor, the Mercedes-Benz C250 1.8-liter turbo at 111.6 hp/L. The turbo four will be joined in the ATS with a normally aspirated 2.5-liter four-cylinder engine and a 3.6-Liter V6 engine when production begins next summer. Frankly, it’s the price of entry in a segment where Cadillac has failed several times with inferior offerings. Continue reading
Ford Employees to Beta Test Latest My Ford Touch Patch
Ford Motor Company will beta test new software designed to ease myriad consumer complaints about the My Ford Touch infotainment system, which caused Ford and Lincoln vehicles to sink to below average in Consumer Reports quality ratings.
Ford’s overall reliability rank among 28 major car makes slipped from the 10th to the 20th spot this year—the biggest drop for any major nameplate in Consumer Reports 2011 Annual Auto Survey. The badly needed software upgrade is coming for 2013 models – and to owners of existing My Ford Touch equipped vehicles. Continue reading
