Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Subaru WRX STI Type RA NBR Special is nearly as fast as a Porsche 918 Spyder at the Nurburgring

Subaru now claims to have the fastest sedan to circle the Nurburgring. Its (deep breath) WRX STI Type RA NBR Special finished a lap of the famed German racetrack in an incredibly fast 6:57.5. That's just half a second behind the Porsche 918 Spyder hypercar. Of course, this WRX STI is a specially-built racecar, a rather distant cousin of the WRX STI Type RA production car that takes its name from this race car. The Type RA NBR Special is an upgraded version of the car Subaru took to the Isle of Man time trial last year, where it broke Subaru's old record. The car was built by Prodrive, and it features a 2.0-liter turbocharged flat-four made for rally use. It now makes over 600 horsepower at 8,500 rpm, which is 50 more than it made last year. The aerodynamic aids have been updated, and they provide 650 pounds of downforce at the car's top speed. The car still has the power-adjustable rear wing from last year. At the press of a button, the driver can change the angle of the rear wing to reduce drag and increase speed on straights. Supporting the power and aerodynamic upgrades are 9-inch wide slick tires at each corner, and a rally-spec sequential transmission that can shift gears in 20 to 25 milliseconds. Related Video:

Subaru takes another look back, this time at the 2004 WRX STI

Here we have the followup to the rally-mimicking Impreza 22B STI that Subaru recently chronicled in its Vintage Garage series: the 2004 Impreza WRX STI. Displacement for the boxer four was upped from 2.2 liters to 2.5, and after noticing how many buyers had installed larger turbochargers on their WRXs, Subaru decided to bolt on one in-house. That gave the final product 300 horsepower and a 0-to-60 mile-per-hour run of just 4.6 seconds.
It was stiffer, it's body from nose to front doors was penned by Peter Stephens, he of the McLaren F1, it came with a driver-controlled center differential, driver-activated cooling spray for the turbos and 300 pound-feet of torque. This is a curio from a time when, after a new WRX STI came out, you started poring through magazines to see how the Mitubishi Evo was going to respond. You can find out more about it in the video below.
