Editor’s note: Ladies and gentlemen, for one night only, it’s the return of Curbside Classics to TTAC. You can catch Paul Niedermeyer’s work (along with contributions from an ever expanding crew of TTAC commenters and more) on a regular basis at the new Curbside Classics site. But this piece? It just had to be on TTAC.
There’s a big difference between creating and re-creating. The proto-hot rodders of yore scoured the junk yards for new solutions, not to replicate. The competition was as much in creativity as it was pure speed. Much of that has given way to endless replication, whether it’s a perfect restoration or a 1000 hp resto-mod. But creative juices are irrepressible, and they were certainly at work here. Want a daily driver Edsel, but not its 1950′s fuel-gulping ways? The solution was just a $200 junkyard engine away. But it had to be imagined first. Now that’s creativity, and a harbinger of the future. Which is exactly what the old car hobby needs: a new model, like this “Eco-Boost” Edsel.
I designed TrueDelta’s Car Reliability Survey to provide information an average of ten months ahead of the established annual surveys. Early last December we shared with TTAC readers that ”Early data on the Ford Fiesta is not good.” Then, in early March, we stated about the 2011 Fiesta and the 2010 Taurus that ”Ford does not appear to have tested either model thoroughly enough.” The late February release on the TrueDelta site went a step farther, asking, “Is Ford slipping?” The answer last week from Ford: “Yes, but we’re going to fix it.”
For years now, Detroit’s inability to compete in the increasingly-important hybrid drivetrain has been part of its larger perception issues, driving the view that the American automakers are both less environmentally responsible and technologically adept than their Japanese competitors. GM waorked through a number of underwhelming hybrid technologies, including its BAS “Mild” Hybrid system and its Two-Mode V8 hybrid, while Ford had to back away from Bill Ford’s precipitous promise that it would build 250k hybrids per year by 2010. For a while now, it’s seemed that Ford and GM were content to avoid direct hybrid competition, focusing on “leapfrog” technologies like pure EVs and the Chevy Volt extended-range electric car… but now it seems they’re going back into Prius-style “parallel hybrids” in a big way.
AOL’s Translogic [via PopSci] takes a look at the LAPD’s brand-spankety new Chevy Caprice PPV, the born-again Pontiac G8 that you can’t buy at a dealership. But rather than looking at the Caprice’s cop car-creaming performance (as did the Michigan State Police), this report focuses on the LAPD’s high-tech toys… which could just make the Caprice’s V8, rear-drive abilities less necessary than ever. Still, between the Holden-powered, rear-drive performance, the footprint-spying night vision camera and the automatic license plate recognition system, the Caprice PPV will probably make you think twice about speeding the next time you’re visiting the City of Angels.
One of the most consistent and valid criticisms of GM’s product development, even in the post-Lutz era, is the class-leading weight that so many new GM products carry around with them. To a number of industry observers, the lingering weight problem that so many of GM’s cars struggle with is a sign of corners cut in the design process. GM’s cars may look, feel and drive better than they did five, let alone ten, years ago, but clearly the battle for truly “world class” products isn’t over.
And now we’re getting some of the first indications that GM is taking the weight issue seriously, as GreenCarCongress reports that GM’s engineers have pulled 13 lbs out of its 3.6 liter direct-injected V6 simply by redesigning its head. Given that the 3.6 is already one of GM’s better engines, and is used in a huge number of its vehicles, that’s a solid first step as The General takes on the battle of the bulge.
The Wisconsin Court of Appeals on Wednesday gave its first ruling on how dashcam evidence would be treated at the appellate level. A three-judge panel decided that the proper legal standard when evaluating a video is to overturn a trial judge’s decision only it is “clearly erroneous.”
The context was provided by the November 4, 2009 arrest of Jeffrey D. Walli in Sheboygan. The court was asked to determine whether Sheboygan Police Officer Brandon Munnik had a valid reason for pulling Walli over in the first place. Munnik claimed that around 11:22pm Walli’s car nearly sideswiped him, so he flipped on his emergency lights, which triggered his dashboard-mounted video camera, and gave chase. Munnik testified that the resulting video showed Walli’s car over the center line and was a legitimate traffic violation. Walli’s attorney disagreed with that take.
While 3D has been getting a big push from Hollywood and the video game and television set industries, consumers have not yet wholeheartedly embraced 3D when it comes to home tv. Stereo photos and videos can be visually stunning and emotionally evocative, but for many people 3D is a no-starter because current 3D tv requires using special glasses of one kind or another. It’s possible though, that consumer acceptance of 3D may come from an unexpected area, the automotive sector. While the technology for autostereoscopic, glasses-free, displays exists right now, there are cost, distance, and viewing angle issues that keep them from being currently applicable for home television sets. Those issues, however, may not exist for automotive applications. In fact, 3D technology is advancing so rapidly that cars may present particularly appropriate applications for the current state of the 3D art.
Rated at between 21/28 (2.5l, manual) and 27/34 (2.0l, auto), the Nissan Sentra is a fairly efficient car, albeit rapidly falling out of contention with its new 40 MPG competitors. Using a computer simulation, the developers of the “split-cycle” Scuderi engine showed that their unique, downsized, turbocharged engine can improve up to a 35% improvement in a “stock” Sentra’s fuel economy, when paired with the firm’s AirHybrid system. It’s not clear, even after listening to a podcast with VP Steven Scuderi, which engine-transmission combination was simulated as the “stock” baseline, but for practical purposes the best-performing Scuderi engine (tuned to match the “stock” engine’s power) achieved between 40 MPG and 32 MPG combined (around 50 MPG CAFE combined, or approaching the 2025 standard). Or, not. The EPA city test reportedly does not show improvements with idle fuel shutoff (stop-start), but Scuderi’s simulated stop-start system shows a 14% improvement over the non-start-stop “stock” Sentra on the same FTP-75 test. Was Mazda bluffing (it’s since said it would bring stop-start to all its cars), or is Scuderi’s simulation off? Scuderi (which has nondisclosure agreements with 11 OEMs and is in discussions with 4-5 more) says it will release more information next week at the Engine Expo 2011 in Stuttgart, Germany.
So, will this MIT-developed “virtual dashboard” render that car you’re about to hit? After all, a three-dimensional representation of the world on your dashboard seems like it would be at least as eye-catching as… you know, reality. And, believe it or not, according to PopSci this is actually a development of a program that was determined to be too distracting. This system, named AIDA 2.0, was developed from
a little robotic dashboard companion called AIDA (for Affective Intelligent Driving Agent), an MIT creation that essentially read a driver’s facial expressions to gauge mood and inferred route and destination preferences through social interaction with the driver. Apparently that was deemed too distracting, so now MIT is back with AIDA 2.0, which swaps the dashboard robot for a massive 3-D interactive map that covers the entire dashboard–because that’s not distracting at all.

There has been an almost-palpable sensation of glee propagating through the various import-leaning car communities I frequent. For nearly two years, they’ve had to sit back and listen to the other guys relentlessly gushing about domestic brand turnarounds. With only a few notable speed bumps, it has been a pretty good run so far for post-bailout Detroit. Market share is up; buyers are coming back; product is improving–a sad state of affairs for the import fanboy. Then, out of nowhere, those cunning deviants over at Motor Trend—known of course for setting the magazine landscape ablaze with their out-of-left-field criticisms and take-no-prisoners, “gotcha”-style journalism—dropped a Molotov cocktail into this Texas-desert-dry landscape of domestic love.
One of the worst things about traffic is that it’s so unpredictable. You can be whizzing along one minute, and crawling with the snails the next. Even the real-time traffic information that a few companies, notably Google, now provide, can be obsolete by the time you’re on your way.But a small cadre of lucky San Franciscans will soon be finding out where the traffic will be before it happens, thanks to a joint project by the California Center for Innovative Transportation (CCIT) at the University of California, Berkeley (my alma mater) the California Department of Transportation, aka Caltrans, and IBM.
One of the cool things about the SAE World Congress is that there’s always at least a couple of radical new engine designs. Scuderi was back with their split cycle compressed air hybrid, only this time with a turbo that lets them use a much smaller piston on the intake side, reducing friction. FEV showed an engine optimized for compressed natural gas, with turbocharging, long intake runners, and a piston designed to increase turbulence. Two exhibitors were at the SAE for the first time. Grail Engine Technologies was showing their atmospheric-valve-in-piston engine that routes the induction through the crankcase and up into the combustion chamber. (Read More…)
BYD made a big splash a few years back when it became the first Chinese automaker to develop a highway-capable plug-in vehicle. That announcement brought a flurry of publicity and a Warren Buffett investment in the firm, but has yet to translate into real plugin sales success. Now, BYD is making a big splash again, by announcing another first for a Chinese automaker: an in-house, stratified-injection, all-aluminum turbocharged engine with a dual-clutch transmission. The 1.5 liter engine creates 178 lb-ft of torque from 1750-3500 RPMs, according to a BYD release, putting “[power] equivalent to a 2.4 liter gasoline engine” through “an advanced 6-Speed Tiptronic dual-clutch design” transmission. BYD insists that the drivetrain’s technology was developed in-house, but some may point to the firm’s ties to VW as a source of the know-how in China’s first modern engine.
What keeps powertrain engineers up at night? C’mon, get your mind out of the gutter. The move towards downsized, turbocharged engines is creating a number of new engineering challenges, and “torsional excitations” grabbed the spotlight at this year’s Society of Automotive Engineers Congress. Steven Thomas, manager of Ford’s global transmission and driveline, research and advanced engineering, illuminated the issue [via Wards].
As we reduce the engine torque, particularly just off idle prior to the boost coming on, we’re going to adversely impact the ability to accelerate the vehicle. I would challenge you all to think about new ways of dealing with this. We could really use new designs to deal with these challenges to optimize the fuel economy, but at the same time deal with (noise, vibration and harshness) and performance issues presented by these new engines.
The problem: the increased inertia of forced-induction engines. The practical example: a turbocharged Fiesta. A worthy adversary, a worthy cause. Let’s do this. (Read More…)
