Specialty Vehicle Engineering's 750-horsepower GMC Canyon fully revealed

GMC's celebrated Syclone will turn 30 in early 2021, but nothing suggests the company will mark the occasion by releasing a modern interpretation of the pickup. New Jersey-based tuner Specialty Vehicle Engineering (SVE) is taking the matter into its own hands by building a limited number of GMC Canyon trucks with Hellcat-like power. Although the original Syclone received a turbocharged V6, the 2021 model gains a 5.3-liter V8 normally found in bigger vehicles, including the Sierra and Yukon. SVE rebuilt it with forged aluminum pistons, forged steel connecting rods, high-lift valve springs, a custom crankshaft and upgraded fuel injectors among other aftermarket parts. It also added a supercharger to raise the eight's output to 750 horsepower and 600 pound-feet of torque. Power flows to the four wheels via a strengthened 8-speed automatic transmission and a permanent all-wheel-drive system. For context, the first Syclone gave the Chevrolet Corvette a run for its money with a fuel-injected, 4.3-liter V6 turbocharged to 280 horsepower and 360 pound-feet of torque. These numbers were spectacular in the early 1990s since the Sonoma that Syclone was based on shipped with the 105-horse Iron Duke four-cylinder as standard. Even compared with the Sonoma GT that got a naturally aspirated 4.3-liter V6 with 195 horsepower and 260 pound-feet of torque, the Syclone was impressive. SVE installed six-pistons front calipers that clamp 13.6-inch slotted rotors, and it kept the factory brakes out back. It also lowered the suspension by two inches in the front and five inches in the back, upgraded the shocks, and added a heavy-duty rear sway bar. These modifications help drivers make the most of the extra power, but SVE hasn't published performance specifications (like the truck's zero-to-60-mph time) yet. Surprisingly, the eight-cylinder weighs almost the same as the V6 it replaces so the engine swap doesn't affect weight distribution. Visually, the Syclone can't be mistaken for a run-of-the-mill Canyon. It wears a deep front bumper, has cladding over the rocker panels and rides on 20-inch alloys. Edition-specific emblems round out the look, and the list of options includes a body-colored grille as well as a folding tonneau cover. SVE's images show a truck painted black, which was the only color offered on the 1991 model, but it's available in any factory hue. Inside, the modern-day Syclone gains special floor mats and a numbered plaque on the dashboard. Leather is optional.

GM is the latest automaker accused of diesel emissions cheating

Volkswagen and Ram need to make room on the diesel-emissions bench for General Motors. America's largest automaker was accused in a lawsuit on Thursday of rigging hundreds of thousands of diesel trucks with at least three so-called defeat devices to ensure that the trucks would meet federal and state emission standards, even if they generated more pollution in real-world driving. According to the complaint, on-road emissions testing conducted for the plaintiffs found that Duramax-equipped trucks produced NOx pollutants, comprised of nitrogen and oxygen atoms, two to five times higher than legally permitted, and "many times" higher than their gasoline counterparts. The proposed class-action lawsuit was filed in federal court in Detroit on behalf of people who own or lease more than 705,000 Chevrolet Silverado and GMC Sierra pickup trucks fitted with "Duramax" engines from 2011 to 2016 model years. The lawsuit seeks remedies including possible refunds or restitution for lost vehicle value, plus punitive damages. It adds to legal problems for Detroit-based GM, which has already paid about $2.5 billion in penalties and settlements over faulty ignition switches linked to 124 deaths. GM joins at least five automakers whose diesel emissions have been scrutinized by regulators or consumers. They include VW, which has admitted to cheating; Mercedes-Benz parent Daimler; Fiat Chrysler Automobiles, Peugeot and Renault. GM spokesman Dan Flores called the claims "baseless," and said the trucks comply with US Environmental Protection Agency emissions standards and California's own tough standards. Shares of GM were down 69 cents, or 2.1 percent, at $32.50 in afternoon trading, after earlier falling to $31.93. The GM lawsuit was filed by several law firms, including Hagens Berman Sobol Shapiro, which helped reach multibillion-dollar settlements with VW on behalf of drivers and dealers. The case is Fenner et al v General Motors LLC et al, US District Court, Eastern District of Michigan, No. 17-11661. The named plaintiffs are Andrei Fenner of Mountain View, California and Joshua Herman of Sulphur, Louisiana. They said they would not have bought their respective 2011 Sierra and 2016 Silverado trucks, or would have paid less for them, had they known about the alleged rigging. Joseph Spak, an RBC Capital Markets analyst, in a research report said "negative publicity" from the lawsuit could drive buyers to trucks from Ford or even Fiat Chrysler's Ram.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC
