Power Drunk: The New BMW M5 Takes On the CTS-V, E63 S, and Panamera Turbo!

2018 Mercedes-AMG E63 S 4Matic, 2018 BMW M5, 2018 Cadillac CTS-V, and 2017 Porsche Panamera Turbo

Our test of 600-hp cars nine years ago looked very different from this one. Fenders bulged. Eight-, 10-, and 12-cylinder engines boomed. Hoods stretched to the horizon—except for that of the Italian, which carried its engine behind the cockpit. Because nine years ago, rounding up four cars with 600 horsepower meant coming face to face with rare and exotic sporting machines. We called them “the pinnacle of the automotive food chain.” They were a Chevrolet Corvette ZR1, a Dodge Viper SRT10, a Lamborghini Murciélago LP640, and a Mercedes-Benz SL65 AMG Black Series. It was 2009, and as the economy cratered and stiff fuel-economy mandates brewed, it was tempting to assume that the halcyon days of horsepower would soon be behind us. READ MORE ››

2018 Honda Accord Hybrid Chops More Than $4K from Price

2018 Honda Accord hybrid

The Honda Accord, just redesigned for the 2018 model year, now welcomes back a gasoline-electric hybrid variant. Available in a total of four trims, the entry-level Accord hybrid wears a starting price of $25,990; that’s $1530 more than a base Accord LX and $4505 less than the previous-generation Accord hybrid.

Like the regular Accord, which is a 10Best Cars winner, the 2018 Accord hybrid comes standard with a host of convenience and safety items including LED low-beam headlights, dual-zone automatic climate control, adaptive cruise control, automatic emergency braking, and lane-departure warning. Those in search of additional luxuries can move up to the better-equipped EX for $29,780, the EX-L at $32,330, or the top-spec Touring for $35,600.

2018 Honda Accord hybrid

As before, the Accord hybrid is motivated by a 143-hp 2.0-liter inline-four and a 181-hp electric motor, which work together to produce a combined 212 horsepower. Power to the electric motor is supplied by a 1.3-kWh lithium-ion battery pack that rests under the floor as opposed to its previous location in the trunk. That change allows the new model to offer the same 17 cubic feet of cargo space as its nonhybrid stablemates.

Unfortunately, the new Accord hybrid is slightly less efficient than its predecessor, as the new model’s 47-mpg city rating is down 2 mpg from before. Both the current and previous Accord hybrid are rated at 47 mpg on the highway. Look for the 2018 Honda Accord hybrid to reach dealerships before the end of March.

Following Fatal Crash, Some Press Pause on Self-Driving Tests

AZ: Self-Driving Autonomous Vehicles In Arizona

In the aftermath of a fatal crash earlier this week between an Uber self-driving vehicle and a pedestrian, industry leaders and city officials across the country are putting their own autonomous-vehicle testing programs on hold so they can ponder the effect on the vehicles’ onboard safety drivers and consider the road ahead for this fledgling technology.

On Sunday night in Tempe, Arizona, an Uber self-driving vehicle operating in autonomous mode struck Elaine Herzberg, 49, who had stepped into the roadway. She was pronounced dead at a nearby hospital. Uber has since suspended its self-driving-vehicle testing across its operations in Tempe, San Francisco, Pittsburgh, and Toronto.

Although it had no role in the deadly incident (the Uber test vehicle was a Volvo XC90), Toyota said Tuesday it will “temporarily pause” testing of its self-driving systems on public roads in Michigan and California. The stoppage involves Toyota test vehicles operating with the company’s Chauffeur autonomous-mode capability, which handles responsibility for all driving tasks.

“We feel the incident in Tempe may have an emotional effect on our test drivers,” Toyota said in a statement. “This timeout is meant to give them time to come to a sense of balance about the inherent risks of their jobs. We are monitoring the situation and plan to resume testing at an appropriate time.”

Manufacturers were not the only ones suspending autonomous-vehicle testing. As in Arizona, Massachusetts permits autonomous-vehicle testing via an executive order issued by the state’s governor. But in Boston, city officials wanted time Tuesday to contemplate the ramifications of ongoing testing within the city’s borders. The commissioner of the city’s transportation department, Gina Fiandaca, asked two companies testing there to pause operations. They agreed.

“As a precautionary measure, we have temporarily asked NuTonomy and Optimus Ride to pause their autonomous-vehicle testing programs on public streets in Boston,” Fiandaca wrote. “The Boston transportation department will be working with both companies to review their safety procedures to ensure each program can move forward.”

Investigators from the National Transportation Safety Board examine the Volvo XC90 which struck a pedestrian in Tempe, Arizona, on Sunday night.

In Tempe, local law-enforcement officials have been joined by teams from the National Transportation Safety Board (NTSB) and the National Highway Traffic Safety Administration (NHTSA) in investigating the crash. Those teams have reviewed video footage of the crash captured by cameras mounted in the vehicle and have begun collecting electronic data stored on the vehicle, according to the Tempe Police Department. As of late Tuesday, a spokesperson for the department said that no fault has been determined in the crash.

In the meantime, Tempe’s mayor, Mark Mitchell, has issued a statement in support of Uber’s decision to pause its testing.

“The city of Tempe has been supportive of autonomous-vehicle testing because of the innovation and promise the technology may offer in many areas, including transportation options for disabled residents and seniors,” he said. “Testing must occur safely. All indications we have had in the past show that traffic laws are being obeyed by the companies testing here. Our city leadership and Tempe police will pursue any and all answers to what happened in order to ensure safety moving forward.”

It is unclear when Uber may begin testing there again.

2019 Cadillac CT6 V-Sport Puts a V-8 under the Hood

2019-Cadillac-CT6-V-Sport-PLACEMENT
-Cadillac is ramping up the performance of its lineup-topping CT6 luxury sedan for 2019. The CT6 will be available as a V-Sport model for the first time, joining the CTS and XTS V-Sports among Cadillac’s not-quite-full-on-V offerings. However, the CT6 V-Sport is significant not only because it’s a new model but also because it debuts an all-new twin-turbocharged V-8 engine. READ MORE ››

2020 Lynk & Co 03: Sino-Swedish Sedan Spied!

Lynk & Co 03 Sedan (spy photo)

What It Is: A near-production version of the Lynk & Co 03 concept, first previewed last April by the newly created Geely subsidiary with the Lincoln-baiting name. Some of the concept’s exterior elements have been modified for production, such as the larger side-view mirrors and the rear bumper with its low-mounted reflectors. Dual exhaust tips poke out below the bumper, which now incorporates a wide strip that appears to house the reverse lamps. The 03’s front is positively amphibian, the side profile is stubby and ungainly, and the back is as bland as envelope adhesive. Clearly, Lynk & Co is not going to impinge on fellow Geely brand Volvo’s position as a design leader. Still, we’re not brushing it off, as this ordinary compact sedan has an extraordinary business plan backed by billions of dollars. READ MORE ››

Deep Dive: Cadillac’s New, Exclusive 4.2-Liter Twin-Turbo V-8

Whatever you do, don’t call it Northstar. According to John Rydzewski, assistant chief engineer of the all-new 550-hp Cadillac V-8 engine, the powerplant was called many things during its roughly four-year development, but in the end they’re just calling it exactly what it is: twin-turbo 4.2-liter V-8. No funny alphanumerics or drawing on history here. Considering the Cadillac brand’s devotion to letters and numbers for all of its nameplates except the Escalade, we’re a little surprised something like NS2 didn’t wiggle its way into its lexicon.

General Motors devotees will remember the Northstar as the first and—aside from the engine powering the limited first-gen Corvette ZR-1—the only DOHC V-8 that GM has produced. It was a silky-smooth mill in its day that served in the top-range Caddys, Oldsmobiles, Pontiacs, and Buicks. But this new engine isn’t much like that one.

Starting at the top, it certainly looks different. That’s because the rotocast aluminum heads have a reversed flow, creating what is called a “hot V,” to feed two Mitsubishi Heavy Industries TD03 twin-scroll turbochargers nestled in the valley of the engine. This arrangement is common among the German automakers, with Audi, Porsche, Mercedes, and BMW all running hot-V twin-turbo V-8s. Positioning the turbos as close to the exhaust ports as possible is advantageous to response and efficiency, and it also simplifies exhaust plumbing to allow the turbos to receive even exhaust pulses from a cross-plane V-8. Air-to-liquid intercoolers also located atop the engine reduce the intake temperature before the air makes its way through cast aluminum intake manifolds and into the cylinders.

The sandcast aluminum block is a clean-sheet design, according to Cadillac, and it is fitted with a 10-quart sump, cross-bolted main bearing caps, a forged steel crankshaft and connecting rods, pistons from Mahle, and 5000-plus-psi direct fuel injection. The compression ratio is 9.8:1. The exhaust manifolds are integrated with the hot side of the turbo housings, which encase titanium turbine wheels spinning at up to 170,000 rpm while pressurizing the intake manifolds with as much as 20.0 psi of boost.

Both intake and exhaust camshafts feature cam phasers. Hydraulic lifters acting on roller finger followers can deactivate valves, enabling cylinder deactivation and V-4 operation to save some fuel. The 4.2’s default firing order is 1-5-4-3-6-8-7-2, which is different from that of GM’s venerable small-block engine, and then changes to to 1-4-6-7 in V-4 mode.

Cadillac says the new 4.2 is actually a little lighter and a little more compact than the LT4. We find this hard to believe, considering compact dimensions are among the biggest selling points of GM’s small-block. Engineers point to the shorter block (by 50 millimeters), made possible by bore spacing down to 96.0 mm from 111.7 mm in the small-block.

For now, this new 4.2 will live exclusively in the Cadillac CT6. It will launch in the freshly unveiled CT6 V-Sport with an estimated 550 horsepower at 5700 rpm and 627 lb-ft of torque from 3200 to 4000 rpm. (Ninety percent of the torque is available as low as 2000 rpm.) That’s breathtaking torque, as in it takes the breath out of the competition. The 553-lb-ft BMW M5 is the closest, but an M5 beater the CT6 V-sport is not. Its mission isn’t too dissimilar from that of a V-8–powered Mercedes-Benz S-class, which is to deliver ultrasmooth and quiet operation while still being able to outrun the vast majority of cars on the road when called on.

After the V-Sport launches, a 500-horse version of the 4.2 will join the CT6 ranks sometime in the first few months of 2019, with the only differences being a slightly different exhaust and ECU tuning. All V-8–powered CT6s will receive the 10-speed automatic transmission and an all-wheel-drive transfer case. The front axle runs through the oil pan, ensuring the engine is mounted mostly behind the axle line for optimal weight distribution. While Cadillac’s representatives won’t talk about future product, they made it clear to us that there is potential left untapped in the engine to make an even more powerful version.

Character, specifically under-the-radar smoothness, is the reason for a Cadillac-only V-8. Sure, Cadillac could have slapped an equally powerful small-block in the CT6’s bay and been done with it. While a pushrod V-8 is a very versatile engine, subtlety isn’t on its résumé. Brand president Johan de Nysschen, formerly of Infiniti and Audi, was brought on board to make Cadillac a serious player in the luxury segment. To succeed, Cadillac needs special elements, things it can call its own, and a Caddy-only V-8 is a great start. We can’t wait to see what’s coming next.
