Do Engine Start-Stop Systems Actually Help You Save Gas?

Jul 05, 2016 - 3:21 PM - by AutoGuide.com



Many new cars come with automatic engine start-stop. These systems are designed to save the fuel wasted at idle by turning the engine off when you come to a stop.

These systems are becoming more and more common in cars and trucks. Even the Ford F-150 is arriving with this system as standard equipment, promising more MPGs.

But the fuel spent during idle seems insignificant, right? Even the EPA’s fuel economy tests seem to downplay the significance of these systems. How much fuel can really be saved, and can everyone benefit from this technology, even if they spend most of their commute on the highway?

Here’s how it works for the driver: When you come to a stop, like you would at an intersection and hold the brake while you wait for the light to turn green, the engine will shut off. On cars with manual transmissions, you usually have to put the car into neutral in order for the engine to shut off. As soon as you let off the brake or engage the clutch, the engine will automatically and quickly fire up, so you can get on your way again. These frequent restarts require a different starter motor that’s more robust and paired to a different, tougher battery.

Furthermore, unlike when you turn off your car entirely, the rest of your car’s features will remain on even if engine start-stop system is active. That means you still get A/C, radio, navigation and all that. A bigger battery helps with that, and some cars even feature an extra battery or a super capacitor.

Still, despite updates to the new five-cycle EPA test, it may be hard to see the tangible benefits of anengine start-stop system.

GM Patents New Two-Stage Turbo

Jun 23, 2016 - 9:56 PM - by AutoGuide.com



General Motors has filed a patent application for a new two-stage turbo system.

The filing, published by the USPTO on May 19, 2016, details a two-stage turbocharger where the low pressure turbine and the high pressure turbine are arranged in a series. The brilliance of the new proposal is a bypass system that allows GM to optimize both the high-pressure and the low-pressure inlets for their respective tasks.

According to the filing, typical two-stage turbochargers are configured to operate both turbines simultaneously at low/mid engine speeds, while at high engine speeds, only the low-pressure turbine operates. The issue with this design is it can never completely isolate either the low or high pressure side, forcing inlet design compromises, which in turn can impair low end performance and result in higher pumping loses. GM’s new system proposes to eliminate the compromise.

The high-pressure turbo is linked to the exhaust manifold through the high-pressure inlet duct; the low pressure turbo is connected to the high pressure turbo through a low pressure inlet duct, which links to a connecting channel.-

Bypass is created through a single actuator that lives in the exhaust manifold, it either opens the high-pressure inlet and closes the connecting channel or vice versa.

The system is actually pretty brilliant in its simplicity. The actuator takes direction from the ECU based on engine speed and load, the actuator is a single rotating spindle with discs corresponding to flanges on the high and low pressure sides. The spindle rotates 90 degrees isolating the respective sides of the two-stage turbos.

Isolation allows the respective inlets to be designed for the best possible fluid dynamic performance. This way the maximum available enthalpy is given to the low pressure side in full power operation, likewise to the high pressure side in maximum torque operation.

2016 Cadillac ATS 3.6L Review

Jun 01, 2016 - 4:08 PM - by AutoGuide.com



The Cadillac ATS is a prime example of how the American automaker is looking to the past for inspiration.

Cadillac’s sport sedan is a reminder of a time when luxury cars could be fun and nimble rather than large and gadget-laden. It’s a throwback of sorts, specifically to the impressive BMW 3 Series from late ‘90s to early 2000s. Why would Cadillac look back to a 15-year-old BMW for inspiration? Because that generation of BMW helped give the brand legs. A loyal following of owners lived with their E46 3 Series sedans and then moved up into other, larger BMW vehicles after becoming so smitten with the driving dynamics of the entry-level luxury vehicle.
Cadillac has picked up BMW’s old gameplan and is making fun-to-drive cars in almost all segments. The ATS is a great car for those looking for a premium driving experience, especially at its $34,210 price point, but an upgraded model with the new 3.6-liter V6 engine ups the ante.

10 Future Collector Cars That Are Affordable Now

May 20, 2016 - 10:56 AM - by AutoGuide.com


You never know which cars are going to be classics; the vehicles that turn up at car shows usually have a mix of sentiment and rarity.

Here are 10 future collector cars we think have potential to gather crowds at car shows of the future. The best part is that they aren’t terribly expensive right now.

Acura NSX (1st-gen)



It was known as “the Japanese Ferrari” — a phrase that still makes us throw up in our mouths a little — but the truth is that these cars really could go toe-to-toe with the best from Europe, and their baked-in Honda reliability gave them an distinct advantage. Drive a first-generation Acura NSX today and you’ll be amazed at how well this quarter-century-old design stacks up, even by modern day standards. The coming of the new NSX has stirred interest in the first-generation cars, but prices are still reasonable: Plenty are still trading in the mid-20s to low-40s, which is a bargain, considering what these cars can do.

Cadillac CTS-V



The CTS-V will be remembered as car that turned the phrase “performance-oriented Cadillac” from a bad joke into a serious threat. The first-generation (2004-2007) had naturally aspirated V8 engines from the Corvette Z06 (5.7 then 6.0 liters, both 400 hp) and came exclusively with a six-speed stick. These BMW-beating road warriors are the best bargains, with some nice ones changing hands under $15k and a few under $10K. 2009-2015 cars gained a supercharger and 556 horsepower, with drop-dead gorgeous coupes and wagons joining the lineup. These cars are quite a bit more expensive, but you can still nab a sedan for around $30k and coupes and wagons under $40k — not bad considering the all-new 2016 version sells for $83,995.
