Acura to roll out NSX Prototype for Mid-Ohio IndyCar race

Acura will tease us yet again with its next-gen NSX when it makes an appearance at Mid-Ohio Raceway before the circuit's IndyCar race early next month. To be fair, the car's in-motion debut won't take the form of a production model - that's still a ways off - the vehicle will be a prototype. It'll be sporting custom graphics and an eye-catching paint (wrap?) job to draw the attention of the spectators, but really, we just want to hear this thing rounding the legendary road course at full chat.
The NSX prototype doesn't look to be much different from the various showcars we've seen over the last couple of years, with the same mid-engined, hybrid V6 power and all-wheel drive all present and accounted for.
The display will take place before the Honda Indy 200 IndyCar Series on August 4. The race itself starts at 3:00 pm and will be shown on NBC Sports Network.

2014 Honda HPD CR-Z

Honda invited us to its Southern California North American headquarters last week to take a spin in a very special CR-Z - one modified with a full complement of Honda Performance Development (HPD) components. While the company has been racing with HPD parts for years, this is the first time the automaker has offered them for its street-legal vehicles, and it has chosen this year's SEMA Show in Las Vegas to be the launch venue. Last year, Honda introduced the HPD Supercharged CR-Z Concept at SEMA - this is the slightly modified production version.
The complete transformation gives the normally placid hybrid hatchback a serious shot of adrenaline thanks to a bolt-on supercharger combined with suspension, tire, brake and exhaust upgrades. In addition to the blower (detailed in a bullet point below), new HPD suspension components lower the car by about half an inch, and firmer spring rates stiffen the ride. Stock 16- or 17-inch wheels are then replaced with HPD 18-inch alloys wrapped in sticky Michelin Pilot Super Sport tires (215/40ZR18 at all corners). The clutch is upgraded, a limited-slip differential is installed and new HPD monobloc four-piston calipers are fitted over slotted and ventilated iron rotors up front (the single-pistons over solid discs on the back axle are unchanged). In the rear, the stock hidden single exhaust pipe is replaced by a free-flow twin-tip exhaust that peers out of a new HPD lower diffuser. Other cosmetic enhancements include an HPD front lip spoiler, rear deck lid spoiler and an HPD emblem kit for each side. To say the CR-Z is transformed by the complete HPD package is an understatement.

Honda unveils new 3.5-liter racing engine

Honda is following Ford's lead and debuting the second twin-turbocharged V6 to be used by Daytona Prototypes in the United Sports Car Championship. The wait won't be long to see it on track because the new engine will debut with the Starworks Motorsport team in a Riley Gen3 prototype chassis at the 12 Hours of Sebring from March 12-15.
The new HR35TT engine is based on Honda's J35 production V6 found in a variety of its models, including the current Accord. The racing version benefits from dry sump lubrication, but is still similar to the production version with an aluminum block, direct injection and single overhead camshafts. It is fueled by 100-octane E10 fuel, but like many racing engines, exact power figures have not been released.
Starworks has had a close relationship with Honda since it won the LMP2 class at the 24 Hours of Le Mans and in the FIA World Endurance Championship in 2012 with a Honda Performance Development ARX-03b chassis and Honda engine. We can't wait to see this new mill hit the track, and see how it fairs against Chip Ganassi Racing's EcoBoost-powered Riley. Scroll down to read the press release for the full details.
