BMW is experimenting with water injection for a 1-Series prototype, suggesting the company is considering the technology for mainstream vehicles.
The engine has been outfitted with nozzles that spray water directly into the engine cylinders, cooling the intake charge. The effect enables a more aggressive engine tuning with higher compression ratios, reduced knock and earlier ignition timing.

BMW suggests power and torque output can be increased by up to 10 percent by combining the various benefits. As an added bonus, the approach is said to improve efficiency and reduce emissions.

Water injection was recently listed as a highlight innovation in ann M4 MotoGP safety car that previewed the M4 GTS package, however the company has not yet officially confirmed if the technology will carry over to the production model.

Most drivers might find it unusual to top off a water tank, as required in the M4 safety car. BMW suggests future production models would use a more convenient replenishing method, taking advantage of condensation produced by the air-conditioning system. Collected water is then drained into a frost-protected tank to avoid freezing in cold temperatures.

“Unless the vehicle is operated in exceptional climatic conditions, the system is fully self-replenishing, thanks to on-board water recovery,” the company notes.

The comments clearly point to production ambitions, but BMW has not yet detailed which models might be the first to arrive on the market with water injection.

Honda is celebrating the start of production for the new Civic Type R.
The high-performance hatchback began rolling off the assembly line at the company’s European production hub in Swindon, UK. The plant will eventually export the Type R globally, however availability will initially be exclusive to the Old Continent.

The first three models to leave the facility were clad in a patriotic red, white and blue exterior paint to match the Union Jack.

The theme could also be an appropriate reference to Stars & Stripes, as the Type R’s highlight component — its engine — is built in America at Honda’s Anna Engine Plant in Ohio. The Japanese automaker released a promotional video showing production clips for the “Built for Europe – Made in America” powerplant.

The new 2.0-liter VTEC Turbo mill delivers 306 horsepower and 295 lb-ft of torque, peaking at 6,500 rpm with a 7,000-rpm redline. Output has increased significantly from the previous Type R, which delivered just under 200 ponies.

Unofficial reports suggest Honda is preparing to bring its European-market Civic to the US. If true, a Type R variant could follow as a new flagship to slot above the Civic Si offerings and rival the Ford Focus RS.

Volkswagen’s diesel offerings have come and gone many times over the years, but they appear to be back for good. Unlike just a few years ago, nearly every model in the lineup is available with a TDI. Are these hybrid alternatives for the highway-dependent worth the price premium? We spent a few hundred miles in a 2015 Passat TDI SEL Premium to find out.
What is it?
The Volkswagen Passat has been many things over the years–an underdog, the enthusiast’s choice, an eight-cylinder sleeper–but at its core, it’s a good, old-fashioned midsize sedan. Our TDI is one of three different engine options. The others are conventional gassers–a turbocharged four-cylinder and a naturally aspirated VR6–and the diesel under the hood of our tester rounds out the field.

The Passat’s TDI differs from that found in Volkswagen’s compact models for reasons we’ll get to shortly. It’s a 2.0-liter, four-cylinder, turbocharged and common-rail-direct-injected diesel. It makes 150 horsepower at 3,500 RPM and 236 lb-ft of torque at 1,750 RPM and in our tester it’s paired to a six-speed automatic transmission. This combination is good for EPA fuel economy ratings of 30 mpg city and 42 on the highway.

As our testing time was spent largely on the interstate, we managed to do a little better than the EPA highway rating, averaging just over 44 mpg according to the multi-function display in the gauge cluster. We didn’t do a hand calculation, but we did manage nearly 800 miles before having to refuel, which backs up the computer’s claim.

So, what’s unique about the Passat’s TDI? It’s all in the exhaust. Unlike the Jetta and Golf/Beetle, the Passat uses a chemical after-treatment to reduce particulate emissions. This allows Volkswagen to turn up the wick a bit without running into the emissions ceiling present in vehicles not so-equipped. It’s added maintenance, sure, but relatively minor as such things go.

What is it up against?
The Passat typically competes directly with the rest of the midsize segment. Fellow niche competitors are found in the Mazda6 and Subaru Legacy. More mainstream examples would be the Honda Accord, Toyota Camry and Nissan Altima.

But the Passat TDI is a bit of a unique snowflake in that it’s the sole representative in the segment with a diesel engine. If you take that into account, the closest competitors would be the various hybrid options, as they tend to be more fuel efficient and thus, like the TDI, tend to carry a bit of a premium. But that’s not to say they compete directly, as diesel and hybrid cars tend to excel in different categories.

What does it look like?
Put all the Passats side-by-side and you’d be hard pressed to tell them apart. Our TDI model sports a badge identifying itself on the rear deck. As a SEL Premium model, there are some other flashy visual upgrades, such as a chrome grille and side moldings.

Otherwise, it’s standard Passat–conservative, classy and somewhat anonymous. It’s fine, if that’s your thing, but there’s a distinct absence of flair, even by German standards.

And the inside?
Our SEL Premium model sounds like it should be fairly loaded, but there are obvious blanking switches on the center console and the cabin, dressed in “Cornsilk Beige” feels airy, but empty.

The seats are relatively comfortable, holding us in place well enough for a full-tank highway excursion that took us up and over the Appalachians. Most of our interior gripes come from the control interface. The infotainment controls on the wheel are context-dependent, so if you shuffle around menus and absent-mindedly flip an arrow that previously controlled, say, song selection, you may find yourself scrolling through Nav destinations instead. Once you get used to it, it works well enough (except when the Navigation can’t find a destination it claimed to know, which happened to us a handful of times).

Our Premium model also came with some other niceties, such as an upgraded Fender audio system, a tilt/slide moonroof, and heated leather seats.

But does it go?
The Passat is a bit of a mixed bag in the “go” department. It handles competently enough and has a compliant ride, but it’s not what you might call “sporting.” It’s… mature? Less in the young professional sense than the AARP sense, feeling more like a golden-era Toyota Camry than an example of German precision.

But the TDI model is not meant to be a dynamic performer, so that’s forgivable. What makes it special is under the hood, so that’s where we’ll focus.

Let’s talk about torque for a minute. Horsepower is the most popular number to describe an engine’s performance, but it only tells half the story. Torque is the other half, but what exactly is it? Shade-tree physics alert!

Torque represents the “grunt” of an engine. Torque is the rotational force being delivered to the drivetrain via the crankshaft. Explosions in each cylinder produce force. That force pushes the piston downward. The piston pushes the connecting rod, which is connected to a pin on the crankshaft. This connection converts the downward(ish) force into rotational force, or torque. Multiply that amount by the number of cylinders that are applying force to the crankshaft at any given moment (it’s never all of them) and you have your advertised torque figure.

Home version: Stick your arm straight out in front of you, palm up. Pretend your arm is 3 feet long from shoulder to fingertip. Take something that weighs 1/3 of a pound and balance it on the tip of your middle finger. That’s 1/3lbs of force at the end of a 3 ft. arm, or 1lb of force for every 1 ft. of arm. That’s 1 lb-ft of torque being applied to your shoulder joint.

Mathematically, making more torque is easy. You just need more fuel and more air to make a bigger explosion. There are two ways to do that, whether you’re talking about a gasoline or diesel engine (forget hybrids for the moment): either increase the displacement or add cylinders, or utilize forced induction to supply more air to the engine. Diesel engines tend to employ the latter.

Horsepower represents how effectively (and more importantly, how efficiently) the engine can put that grunt to work. All else being equal (fuel type, aspiration, etc.), if you make the engine better at producing torque, you get more horsepower at the same RPM. There are many factors at play when it comes to the characteristics of an engine that contribute to its final torque and horsepower outputs, and we won’t get into them here, but suffice it to say that diesels, with their heavy rotational assemblies and energy-dense fuel, don’t lend themselves to being run at high RPM. So the trick to a good diesel engine is pumping a bunch of fuel into a few (relatively) large cylinders and using a turbocharger to supply enough oxygen-dense air for a nice, fat shove of torque.

So, if more torque comes from more fuel (rather than from, say, pixie dust), it should stand to reason that taking advantage of an engine’s thrust results in a mileage penalty. Thus, even in a forced-induction application, it makes sense to engineer the vehicle to spend as little time in boost as possible to maximize fuel efficiency.

Thus, in a (very) round-about way, we’ve arrived at a defining characteristic of the Passat’s performance.

It’s slow.

You may be thinking that a simple glance at the spec sheet would be enough to support this assertion, but when it comes to diesel-powered cars, there’s an illusion of speed brought on by the low-end grunt that can fool the driver into believing this is not the case. But it is. The power comes on as soon as you get into boost, then vanishes just as quickly.

The TDI’s torque band may look wider and flatter than the Colorado Plateau on paper, but when you actually need to summon all the go the engine has to offer, it can be an exercise in frustration. To get to that torque, you first need boost. To get boost, you need exhaust pressure. To get exhaust pressure, you need RPM. To get RPM, you need lower gears.

So, like the gutless wonder powering the Honda or Kia next to you, your TDI will ask the transmission for lower gears. And you shift. And you shift. And then you finally find the power. Then it’s gone.

If you’ve ever been behind a TDI that launched itself onto an on-ramp with gusto, only to find yourself braking to stay off its bumper before you reach the merge area, you’ve seen this in action.

The TDI then is all about expectation management. If you, as a buyer, put a priority on flat-road, long-distance cruising, then there is no better family sedan in this price bracket, period. If you want something that is genuinely fast and fun, you may want to take a longer look at the VR6 model instead.

Leftlane’s bottom line
A competent, fuel-efficient car that appeals more to the frugal than the frenetic. Buy it for the engine, not in spite of it.

Fiat has introduced the updated 2016 500 at a special event held in Turin, Italy, its home town.
Far from an all-new model, the 2016 500 stands out from the eight-year old model that’s currently found in showrooms thanks to minor visual tweaks like a new front bumper with a large air dam framed by a thin strip of chrome trim, oval LED daytime running lights, new-look headlights and redesigned tail lamps with body-colored accents. New paint colors and additional alloy wheel designs essentially round out the list of the major exterior modifications.

Perhaps the most important update for 2016 is found by stepping inside the city car. Upscale 500 Lounge models can finally be ordered with a five-inch touch screen that runs Chrysler’s Uconnect infotainment system. Other updates include more ergonomic seats, a new three-spoke steering wheel and additional sound-deadening material.

In Europe, the 500 is available with a 1.2-liter four-cylinder engine rated at 69 horsepower, a 0.9-liter TwinAir two-cylinder mill offered with either 85 or 105 horsepower or a 1.3-liter Multijet II turbodiesel that makes 95 ponies. A manual transmission comes standard, and select engines can be ordered with a semi-automatic gearbox at an extra cost.

Full technical details about the U.S.-spec model are not available yet, though it looks like the 101-horsepower 1.4-liter MultiAir will carry on without any changes.

The 2016 Fiat 500 will greet the public for the first time this September at the Frankfurt Motor Show, and it is scheduled to go on sale shortly after. Pricing information will be published in the coming weeks.

What’s next?
The aforementioned changes also apply to the 500C. The hot-rodded 500 Abarth will also benefit from a handful of minor updates, but it is not expected to make its debut until later this fall.

The National Highway Transportation Safety Agency has stepped up its criticism of Fiat Chrysler Automobiles as the automaker faces a public grilling for its alleged mishandling of 23 different recall campaigns.
The agency scheduled today’s hearing to gather public comment on its findings, however officials already appear to be readying a potential enforcement action for any violations of federal regulations.

The company is accused of failing to properly communicate with the NHTSA, failing to notify owners of defective vehicles in a timely manner, implementing repairs that did not resolve safety issues, and failing to promptly arrange parts supplies, among other gripes. In some cases, owners allegedly had to wait more than 18 months before parts were available to fix their vehicles.

In his strongest language yet, NHTSA Administrator Mark Rosekind argued that “there’s a pattern that has been going on for sometime frankly,” according to quotes from the hearing published by The Detroit News.

“In every one of the 23 recalls, we have identified ways in which Fiat Chrysler failed to do its job,” added NHTSA Office of Defects Investigation head Jennifer Timian. “Problems with the information that Fiat Chrysler reports — or in many cases, fails to report — to NHTSA are also widespread.”

The alleged misbehavior “impedes our ability to do our job,” Timian said, arguing that FCA’s lack of proper communication “obstructs our ability” to conduct oversight and pursue safety issues.

Other officials spoke of a “lack of urgency,” echoing statements made about General Motors in the wake of the ignition-switch fiasco.

The agency has not yet outlined its next step, though Rosekind suggests there will be “action soon after the docket closes.” Potential moves include forcing buybacks of recalled vehicles, levying fines or reaching a settlement with a consent agreement.

“Some of the things we’ve done were sloppy,” admitted FCA’s head of safety and regulatory affairs, Scott Kunselman, in a follow-up interview with The Detroit News. “We absolutely had no misintent.”

Tesla delivered 11,507 vehicles during the second quarter of 2015, marking the best three-month stretch in the company’s short history.
Tesla announced on Thursday that it delivered 11,507 units of its Model S sedan during the second quarter of 2015, marking a sharp improvement over the 10,030 units it delivered during the first three months of the year. Q2′s sales tally set a new company record for quarterly sales.

At the mid-way point of the year, Tesla has delivered 21,537 vehicles. Tesla has previously stated that it plans to deliver 55,000 units by year’s end.

Although well off the pace of that sales goal at the current time, Tesla should get a significant boost later this year when it introduces its highly anticipated Model X SUV. If all goes according to plan, the Model X will hit retail outlets during the third quarter.

Late last year Tesla CEO Elon Musk indicated that the company planned to produce about 23,000 units of the Model X in 2015. However, the project has faced some delays since then, so it’s unclear how many units Tesla will actually be able to produce. But even at half of its projected production rate, the Model X should ensure that Tesla hits its 55,000 unit goal.

Wall Street reacted favorably to Tesla’s strong second quarter with shares in the EV maker up around two-percent in early trading.

Ford has issued a safety compliance recall for approximately 433,000 new vehicles, including the 2015 Focus, C-Max and Escape.
The company has discovered a problem with the body control module that allows the engine to keep running after the driver has turned the ignition key to the ‘off’ position or pressed the start/stop button.

The company is not aware of any accidents or injuries related to the issue, however the behavior runs afoul of federal safety regulations regarding theft protection and rollaway prevention.

“My Ford Escape 2015 wouldn’t shut off … I didn’t realize [the] car was on after I had [parked] … without the keys in the ignition,” reads one complaint published by the National Highway Traffic Safety Administration.

The company will update the body control module software in affected vehicles to resolve the apparent glitch.
