According to a recent report by What Car, Audi has plans to release a small plug-in hybrid boasting fuel efficiency in the neighborhood of 1 liter per 100 km—or roughly 235 mpg. Audi’s head of research and development, Wolfgang Durheimer, told What Car that although the car hasn’t yet been confirmed for production, it’s one of several new plans for high-efficiency vehicles he has been trying to institute since taking over his post in September.

The vehicle would be built around the carmaker’s A1 platform, but would likely be fine-tuned for optimal aerodynamics and outfitted with ultra-lightweight materials. The conceptual and technological underpinnings of the car are based around parent company Volkswagen’s “one-liter” program, which has been experimenting with vehicles capable of hitting the vaunted efficiency mark for more than a decade.

Confirmed for release in Europe for 2014, the Volkswagen XL1 will be the first “one-liter” production vehicle ever sold. A prototype of the two-seat XL1 was photographed testing in March sporting a set of gullwing doors. The car draws its power from a two-cylinder turbo-diesel engine paired with a 27-hp motor attached to a small lithium ion battery pack. The car will be tuned to switch between electric and gas-electric modes depending upon use to ensure maximum efficiency. Audi’s version of the vehicle would likely carry a very similar configuration.

Despite the range of measures geared at optimizing efficiency, Audi’s attempt at a one-liter would remain true to the carmaker’s luxury standards. “I’m not talking about a car with a lot of deficiencies and things lacking, but a car that delivers everything that a car needs to deliver to the customer, in terms of seat space, climate conditions and comfort,” said Durheimer to What Car.

It’s still not known how much the VW XL1 will cost when it hits the market next year, but given the cost of high strength, light-weight materials, it figures to be very expensive for a two-seat car. An Audi version of the vehicle would likely add a significant luxury premium to whatever the XL1 costs. Neither car would be expected to post earth-shattering sales numbers, and at this point it’s a relative long shot that either are headed to the U.S. market.

Still, Volkswagen and Audi are further demonstrating their commitment to high-efficiency vehicles through a wide range of drivetrain configurations headed to different markets around the world. After establishing a reputation for clean diesel TDI vehicles in the 2000s, both Volkswagen and Audi have lagged somewhat in releasing battery powered hybrids or plug-ins. Now, with multiple plug-in concepts headed to market and in test fleets, it’s beginning to look like the Volkswagen Group’s answer to fuel economy will be “all of the above.”

First Drive: Toyota Prius c

It’s been twelve years since the Toyota Prius first came on to the American stage. Thought of as a science experiment then, and in many ways it was, now in it’s third generation the Prius Liftback IS the face of Toyota.

While the hybrid and plugin electric market may only be 2.5% of all vehicle sales in the U.S., the Prius accounts for more than 50% of those sales. The most shocking statistic is that 96% of all Prius’ sold, are still on the road today. Looking to expand the sales of the Prius, Toyota have expanded the sub-brand of Prius into four models, with the goal of the Prius family of vehicles surpassing Camry in sales.

The first expansion of the Prius family was the v, not quite a crossover, yet more than a wagon, it was Toyota’s move to get growing and active families more space to fit their lifestyle without compromising fuel economy or the integrity of the Prius name. The Plugin Prius will be the current Liftback model that will have the ability to drive 15 miles on pure electric, then revert back to a standard Prius Hybrid once the charge has been depleted. The last component is the source of our review, and that is the Prius c. It is a B-segment car, which will be competing against the likes of Toyota’s own Yaris and iQ, along with the Mazda2, Ford Fiesta, Chevy Spark, Honda Fit, Nissan Versa, Kia Rio and Hyundai Accent.

Powering the Prius c is an updated version of the venerable 1.5 liter inline four cylinder engine. It has been updated to improve efficiency with lighter weight valve springs, lighter tension weight piston rings along with a few other items like the elimination of an accessory belt so now that the power steering, air conditioning and water pump are all driven via electric motors to reduce drag and friction and improve fuel economy. This is paired with a Ni-MH battery pack that is about 2/3rds the size of the one found in the Liftback, which provides an additional 25.9 horsepower to the 73 horsepower engine. The transaxle in the Prius c is an all electric unit that has no belts.

Fuel economy is the raison d’etre in the Prius family and the Prius c will deliver that in spades. Rated by the EPA 53 city, 46 highway and 50 combined. We had the opportunity to drive for a short 25 mile loop that was an equal mix of surface roads and highway. On the surface roads we pulled down 63.5 mpg without really making an effort to maximize fuel economy, and at the end of the loop we had a combined 54.7 mpg, and that was while driving highway speeds of 70-75 mph. Keeping with the rest if the Prius family, the c also has start/stop technology, so that the car is running only when it needs to when stopped in traffic. If you are in stop and go driving, this is an excellent way to save a few extras drops of fuel.

Lest you think this B-segment car is cramped inside, it is not. Front seat passengers have plenty of room, no fear of rubbing shoulders with your passenger. For back seat passengers, two normal sized adults will be able to ride comfortably. We had the drivers seat set for us at 5’11”, then jumped in the back seat behind and were able to get in and out with no problem, and our knees were not touching the back of the driver seat either.

The rear seats do fold in a 60/40 arrangement allowing for good load flexibility, bicycles and snowboards will have no problem fitting inside. With the seats up there is 17.1 cubic feet of space in the hatch area, which should be more than enough room for day to day items, or runs to the grocery store.

In the upper trim levels Toyota have made Softex synthetic leather an option. Listening to their consumers, Toyota have eliminated the use of natural leather in the Prius family of cars. The Softext in our test car, was comfortable, had a quality feel to it, and was grippy so that we did not slide around in the seat.

There will be four trim levels to the Prius c, One, Two, Three and Four. Stepping up to trim level’s Three and Four will net you a smart key, which offers the ability to not have to take the key out of your pocket to get in the car, or need it for starting. The upper two levels also get you the top end audio system with navigation. It has a 6.1 in touch screen with AM/FM/SirusXM/HD Radio and also will play CD’s along with MP3 and WMA files through a six speaker system.

All trim levels have bluetooth as standard but trim levels Three and Four allow for advanced voice recognition. The top end audio system also includes Entune. Entune is a system that Toyota have developed that works with the data connection on your smart phone to supply Pandora, iHeart Radio, OpenTable, MovieTickets.com along with real time traffic, weather, fuel prices, sports scores and weather to you.

You register on a specific Toyota website with your cars VIN number, and then you can assign up to four different phones to the system so that everyone can taylor the system to themselves, if multiple people in a household share the car.

The Prius c also contains a 3.5 inch TFT display to the right of the offset digital speedometer. There are multiple levels of menus to explore within. Items like energy monitors, drive information, scoring the last 100 drives and how economical the current one is, 5 minute consumption. There is an ECO Savings level where you can program the current cost of gas in, and also the mpg of another vehicle to see how much you are saving with the Prius c. It also calculates the current cost of your current trip, and past trips, and brake it down into a cost per mile. It will also grade you on how economically you are driving and braking on a scale of 1-5 and display it in a bar graph.

Many people worry about safety in cars that are as small as the Prius c. To address this Toyota is including nine standard airbags along with items like ABS, traction control, vehicle stability control, brake assist, brake force distribution and smart stop.

Smart stop is a system that intervenes when both the brake and gas peddles are pressed at the same time. In a panic situation one might press down hard on both peddles without meaning to. The system senses this, and disengages the gas, it also incorporates a hill assist into the system so that if you are on a hill and stopped, you do not roll backwards when transferring from the brake peddle to the gas peddle.

Pricing for the Prius c in trim level One starts at $19,710, Level Two is $20,760, Level Three is $22,395 and Level Four is $23,990, all prices include the $760 destination fee. While this is certainly on the higher end of the B-Segment price structure, cars like Ford’s Fiesta can quickly top $20,000 as well once they are optioned up. The base price of the Prius c is about a $2,000 premium over the Yaris to give some context.

Out on the road the Prius c drives very well. While the handling can’t be called sporty, it is very competent. It is very agile, has a better ride quality than the Prius Liftback or v, and also transmits less road noise through the tires than the Liftback or v as well. The Prius c engineers took extra time to mitigate as much NVH from the car as possible and their work shows.

Acceleration in city traffic from 0-40 miles an hour is good, though not quick. Merging onto the highway the power can be best described as adequate. It is able to get on to freeways and merge without drama, and while you may feel you need to be going faster or accelerating quicker, once you look at the speedometer, you will see you’ve already gotten up to the speed of surrounding traffic. The car can engage an EV mode where it can run up to a mile with a max speed of 25 miles an hour.

The Prius c was able to run 75 miles an hour on the highway with no issues, it was not moved around by semi’s going past, it felt very stable, and the interior is quiet enough to hold a conversation in a normal tone of voice.

While the other versions of the Prius have never excited us all that much, we feel that the c is the first Prius that we can get behind. It truly was a fun and satisfying car to drive. In a time when gas is again approaching $4/gallon in the U.S., having a car that can pull down 50 mpg is an attractive proposition. And when that proposition asks very few compromises from you, it’s even more so. No the car is not a sports car, or a sporty car, what it is, is a small car that gets the job done, can be well equipped, and you don’t mind driving. While in the past, and even now with the Liftback and the v, the Prius’ could be described as automotive appliances, the c does not have that vibe, it feels like a car first, a hybrid second.

We’ve talked about it for quite some time, and now it’s finally here, the first new model of the Prius line, it’s the Prius V. V is for Versatility! The Prius V has as much cargo capacity as most CUV’s on the market today, yet returns the superior fuel economy you would expect from a Prius. As you may remember we had a chance to drive a Prius V back in June and wrote about it here on the blog.

Now, the Prius V’s are here, and we have them available at both the Toyota Santa Monica and Toyota Hollywood stores! We showed the Prius V off at the AltCar Expo, and we also shot this test drive video for you, have a look.
